1. INTRODUCTION

The Nera Evolution Series microwave radio dramatically changes the operations for wireless transmission network owners. With the ability of a common platform architecture, which is fully software configurable; transmission capacity, system configurations and transmission interfaces can be changed to adapt to future needs. Evolution Series dramatically reduces the cost of ownership. With significantly reduced number of parts and high MTBF Evolution Series ensures maximum uptime and low maintenance. The Evolution Series microwave radio system is designed to transmit data rates from about 6 Mbit/s to 1550 Mbit/s, in the frequency bands from 4 GHz to 40 GHz. The configuration of capacity and modulation is software configurable, giving an optimal balance between system gain and spectral efficiency. Network operators can with the Universal IFU system easily future proof the network as the microwave radio can easily adapt to the evolution of the transmission network. Growing traffic and the convergence of network technologies causes changing requirements, such as capacity upgrades, change of transmission systems between PDH, SDH/SONET and pure Ethernet; all this is simply implemented by software configuration change and change of interface units. The available interfaces range from E1, T1, E3, DS3, STM-1/OC-3 and STM-4/OC-12 to 10/100BASE-TX and Gigabit Ethernet. The Evolution Series product can be configured to work in two different modes, METRO (SDH based) and XPAND (Hybrid Ethernet/PDH based). In both modes it is possible to either have a split mounted system with IFU and ODU or an optimized long haul system with low loss RF-branching providing the best system gain for high capacity systems. Payload capacity on each RF channel is configurable and is enabled by SW licences. With the Universal IFU changes and upgrades can be done by the user without HW changes to the basic IFU platform. The Universal IFU is used in METRO and in XPAND when more than 16 E1/T1 interfaces and/or more directions are needed. In addition the Access IFUs with fixed interfaces and one antenna direction are available. In the following the main features for each configuration mode is described METRO features (ETSI and ANSI)

1.1 Features The Evolution Series microwave radio utilises the latest advanced technology, a high degree of RF circuit integration, using Monolithic Microwave Integrated Circuits (MMIC), combined with advanced direct RF modulation, enabling a broadband, revolutionary compact design for a high power microwave module. The patented technology enables a revolutionary low power consumption and high reliability due to fewer parts in the radio unit. The modem contains multidimensional coded modulation, combined with a powerful block code. The resulting two-stage error correction improves system margin over traditional single FEC systems such as QAM, TCM or MLCM. The modem is extremely flexible, enabling an optimum configuration for all capacities and channel plans. The XVCR can be used for all transmission capacities and covers the whole band, both high and low part. The same XCVR is used in both Split Mount Access Systems and Long Haul Systems. For Long Haul Combiner Space Diversity XCVR is also available. Split Mount Access Systems are using an ODU Unit which consists of the XVCR and a Diplexer Unit. Most frequency bands can be covered by four ODU variants for the whole band. The frequency setting is easy and is performed locally or remotely by the LCT function. The ODU can for most frequency bands be mounted directly on the antenna, both in unprotected and protected configurations. The ODU can also be mounted on the antenna pole, using a short flexible waveguide to the antenna. The InterFace Unit (IFU) is an extremely modular system, catering for the various system configurations and traffic interfaces by plug-in units. The IFU can easily be expanded from a single channel system up to a traffic node handling up to 8 ODU/XCVRs. The IFU contains the user interfaces, baseband processing and multiplexing, management and radio interface. The demodulator contains an integrated digital interference canceller, which can be used to provide the XPIC function, enabling two carriers to be transmitted over the same frequency, using dual polarised antennas. The optional embedded ADM/DXC function provides multiplexing for user traffic into the STM-1/OC-3 signal. In traffic node systems, the digital cross connect (DXC) routes the user traffic between the various link directions without the need for cabling or external multiplexers. Chain, ring, star and mesh topologies are supported, with individual choice of unprotected or protected (SNCP) traffic circuits. The multiplexer supports a mix of traffic types, such as E1, T1, E3, DS3 and Ethernet. In XPAND mode an embedded PDH cross-connect allows flexible routing of Ethernet traffic and X-connect of E1/T1-traffic between the radio interfaces and the user interfaces. The equipment configuration and licences can be stored in an external file. When a new Supervisory Unit is inserted, the equipment configuration can then easily be restored to the radio equipment. The configuration can also be copied to other terminals.


1.2 Network Applications The Evolution Series microwave radio is ideally suited for a wide range of applications. Due to the flexibility in configurations, the choice of traffic interfaces and the capacity scalability, it can easily adapt to the specific requirements of a given network application. The flexibility and ease- of upgrade, future proof the investment, as the equipment can grow with the increasing traffic demand as well as easily adapt to other transmission technologies.

Mobile (BTS) Backhaul

- The Evolution Series microwave radio is ideal for demanding and critical application such as backhaul of BTS traffic. Where loss of traffic directly results in loss of revenue, reliability and maximum uptime are critical parameters for the network operator. The Evolution Series reliable and flexible architecture as well as high system gain, ensures increased availability of the offered services, and a secured revenue stream. The optional embedded ADM multiplexer and cross-connect enables routing of traffic without the need for external cabling. Further, the traffic circuits can be individually protected via ring or mesh topologies, and various traffic types can be mixed, sharing the transmission capacity of the radio. The radio can be configured for a wide range of capacities, ensuring an optimal utilization of the available spectrum as well as capabilities for upgrading when traffic demand increases or new services are introduced.

- With the introduction of HSPA in the networks, as an overlay network or a Greenfield installation, the aggregate capacity demand typically raise above 30 Mbit/s. High density Ethernet/PDH and/or SDH radios are needed, and a common platform system, represent large savings in the network operation, compared to more traditional network designs.

Long Haul Trunk Systems

- For long haul applications where high capacity and high availability is crucial the low loss optimized RF-branching system is the best choice. These systems are the choice when the need is multiple STM-1/OC-3, STM-4/OC-12 or Gigabit Ethernet connections. Integrated ADM is also available, enabling access to TDM tributaries without the need for external multiplexer. Applications can be pure backbone radio transmission networks and also back-up links for fibre connections or closing of rings where fibre can not be used.

LMDS/FWA Backhaul

- LMDS/FWA backhaul. The Evolution Series radio is well suited for backhaul of traffic from Point-to-MultiPoint radio access systems like WiMax. With a selectable capacity, ranging from about 20 Mbit/s to 600Mbit/s, the Evolution Series radio can easily be deployed in small network as well as in larger constellations and networks with several sites linked together. The choice of pure Ethernet/Gigabit Ethernet, 155Mbit/s SDH/SONET, or a combination of TDM (E1/T1/E3/DS3) with Ethernet/Gigabit Ethernet, makes the Evolution Series suitable for any FWA network installation.

- DSLAM backhaul. The introduction of xDSL services can in some cases uncover a new challenge. The local transmission network may only be dimensioned for the POTS traffic and is not suited for high speed data. Upgrading the local network to fibre might not be feasible due to time and/or cost of such upgrade. The Evolution Series microwave radio offers an easy and flexible solution to this challenge. The Evolution Series microwave radio can offer backhaul of the DSLAM to the optical backbone network, whether the network interfaces are PDH, ATM/SDH/SONET or Ethernet/Gigabit Ethernet. With the Evolution Series radio, the various traffic types are catered for merely by change of interface units.

Private Networks Operators

- Corporate/Campus Networks. The Evolution Series radio is a good alternative to more common unlicensed microwave solutions. With higher capacity, choice of pure Ethernet/Gigabit Ethernet, 155Mbit/s SDH/SONET, or a combination of TDM (E1/T1/E3/DS3) with Ethernet/Gigabit Ethernet, makes the Evolution Series suitable for most private networks, whether they are carrying legacy services or data only. Flexibility and simplicity, combined with a predictable reliability, proves for many network owners to be an unbeatable combination.

2. SYSTEM DESCRIPTION GENERAL

The Evolution Series microwave radio system has the option of an ODU based system or a Long Haul RF-branching based system. The same basic units like XCVR, IFU and interface cards are used in both systems. Further the system has two configuration modes; METRO (SDH/SONET) and XPAND (Hybrid PDH/Ethernet). The embedded SW can handle both modes and the choice of mode is done during terminal configuration.

2.1 ODU based systems These systems comprise indoor part (IFU), outdoor part (ODU) and antenna. The IFU and each ODU is interconnected with coaxial cable which carries transmit and receive user traffic, management communication between the IFU and ODU, and the power supply to the ODU. The ODU can be mounted directly to the antenna or to a pole when this is needed.

Figure 2-1 ODU based system


2.2 Optimised Long haul systems 4-11 GHz These systems are most commonly indoor mounted but a split mounted version is also available. The system comprises one to five IFUs with interface units and power supply connection to the system, up to ten XCVRs and the RF branching system. Connection to the antenna is by elliptical WG. The indoor system is mounted in a 19” rack. Configurations

3. METRO SYSTEM DESCRIPTION – ACCESS & LONG HAUL

Evolution Series METRO is a high capacity system configuration with transmission capacity of 155 or 311 Mbit/s per XCVR/ODU and up to 10x155 Mbit/s per link. CCDP configuration with XPIC is available in all frequency bands for all modulation schemes. The transmission protocols are SDH or SONET. Ethernet traffic is transported using the Ethernet over SDH standards; GFP, VCAT and LCAS. The equipment can be configured for a wide range of network configurations including terminal and traffic node with two, three or four antenna directions with Add/Drop and digital x-connect of traffic between the directions.

Figure 3-1 SDH/SONET Ring Network

Evolution Series provides a lot of freedom for configuring a terminal to fit with the user needs. The main building blocks are the Line Interfaces (LIU), the Radio Interfaces (RIU), the optional DXC and the Main Data Switch (MDS). The MDS makes connections between LIUs, DXC and RIUs. See Figure 3-2 below. STM-1/OC-3, Gigabit and STM-4/OC-12 interfaces can be connected directly to a RIU. The PDH interfaces (E1/T1/E3 and DS3) have to be connected through the DXC. In a repeater site RIUs from two directions can be interconnected. In addition the terminal can be equipped with Auxiliary Interfaces.

3.5.1 Mapping and multiplexing DXC Unit & DXC Frame The equipment supports both SDH and SONET mapping. For Ethernet traffic, GFP mapping is used. See chapter 4.3.2 for more details. The DXC supports SDH and SONET Mapping and multiplexing of E1, E3 and DS3 according to Figure 3-3 and Figure 3-4.

Figure 3-4 SONET Mapping and Multiplexing


3.5.2 Mapping and multiplexing STM-4/OC-12 A terminal with STM-4/OC-12 interface supports Mapping and multiplexing according to Figure 3-5. If the payload contains four individual STM-1/OC-3 signals the payload may be partially populated. This allows the use of the STM-4/OC-12 interface on a link with lower capacity. If the payload is a concatenated signal a link capacity of 622 Mbit/s is mandatory.

Figure 3-5 SDH and SONET STM-4/OC-12 Mapping

3.5.3 Cross-connect support The DXC Unit or the larger DXC Frame provides the SDH/SONET multiplexer functionality. It can be configured as terminal, ADM with two transmission directions or as X-connect with up to four transmission directions. It can also be used without ODU as a DXC terminal. The node has a non-blocking cross-connect capability at VT1.5, VC-12, VC-3/STS-1 and VC-4/STS-3 levels with a total cross-connect capacity of 4×VC-4/STS-3 (DXC Unit) and 8×VC-4/STS-3 (DXC Frame). The data traffic can be a mix of TDM and Ethernet.

3.5.3.1 Sub Network Connection Protection In a ring or mesh topology the traffic signals can be protected by SNCP. This is done by transmitting the relevant VC/SPE in both directions in the ring. At the receive direction, the available or better-quality signal is selected. Manual switching is also possible. The following switching criteria are used:

• AU/TU AIS and AU/TU LOP alarms • Path error performance • Unequipped Signal and Trace Identifier at VC level • User Command from the LCT or from EM/NMS.

The protected VC-n/SPEs circuits can be selected from any STM-1/STS-3 signal connected to the DXC.


27

3.5.4 Synchronisation The terminal contains an optional SETS function included in the DXC. In RST mode the SETS function is not required and the incoming 155 Mbit/s signal is transmitted without re-timing. Transmit and receive directions are independent from each other and can have different timing sources. In MST mode the SETS function is providing the equipment clock. The SETS function can be synchronised to one of the following sources:

• 155 Mbit/s signal from line or radio direction • 2 MHz clock input • One selectable 2 or 1.5 Mbit/s tributary input signal • Internal oscillator (free running)

The user sets the available synchronisation references sources in priority order. The highest quality source is used to synchronise the equipment clock, but if there are several sources available with equally high quality, the source with higher priority is used. If a timing source is not available (loss of signal) or its timing signal is outside tolerances, the SETS function will select the next available source with the highest quality.

3.5.4.1 Synchronisation status messaging Synchronisation status messaging can be used to ensure that the best available timing source will be used. The messaging is also used to prevent timing loops in SDH ring and mesh networks. The status messaging is transferred in the S1 byte in the Section Overhead. The synchronisation status quality levels are shown in the table below.

Abbr. ETSI Ref. Quality G.811 QL_PRC Primary Reference Clock (PRC) defined in ITU-T rec. G.811

G.812T QL_SSU T Transit node clock defined in ITU-T rec. G.812 G.812L QL_SSU L Local node clock defined in ITU-T rec. G.812 SETS QL_SEC Synchronous Equipment Timing Source (internal oscillator)

Do Not Use QL_DNU Do not use for synchronisation (to prevent timing loops)

Table 3-1 Synchronisation quality levels

In case the synchronisation status message is not contained in the synchronisation input signal, for example in the external 2 MHz or in 2/1.5 Mbit/s tributary input signal, the quality level can be defined manually by the operator.

3.5.5 Section Termination The radio channel can be configured with RS- or MS-termination according to ITU-T Rec.G.783. When the radio is configured with DXC or tributary units, the radio will always be configured for MS-termination. When the equipment is not equipped with DXC or tributary units it will be configured with RS-termination and the radio link is a regeneration section.

3.5.6 Scrambling / descrambling functions The system contains both a STM-1/STS-3 scrambler/descrambler according to ITU-T Rec. G.707 and a radio specific scrambler/descrambler, which randomises the transmitted digital signal in order to make the RF power spectrum as uniform as possible, irrespective of the transmitted data.


3.5.7 Section/Transport Overhead (SOH/TOH) Use of TOH/SOH is according to ITU-T Rec. G.707. Access to bytes in MSOH at a regenerator is according to ITU-R Rec.750. A description is given in Table 3-2: Shaded bytes can be used for 2Mbit/s, 1.5 Mbit/s or Ethernet wayside channel. These bytes and the E1, E2, F1, MS#1-3, Z1#1-2, or Z2#2 bytes can be used as 64 kb/s user channels. Maximum three 64 kb/s channels can be allocated per SOH/TOH. In addition there are two user channels in the NERA Frame overhead.

3.8 Ethernet features

3.8.1 Ethernet over SDH/SONET Mapping Ethernet traffic is in METRO mode transported over the radio link by mapping Ethernet traffic into SDH/SONET containers. Standardised GFP-F mapping with Null Extension Header according to ITU-T G.7041/Y.1303 is applied. Payload Frame Check Sequence is not used (PFI=0). Mapping into VC-12, VT1.5, VC-3 and VC-4 containers are supported. The transmission capacity is scalable from one VT1.5/VC-12 to four VC-4 (600 Mbit/s). The VC containers can be mapped toward both radio or line interfaces. This can be very useful if existing SDH/SONET network is available for some of the capacity. For high capacities the LCAS feature is superior to Link Aggregation as the link even if consisting of several ODUs or external STM-1 connections, is seen as one channel from the Ethernet layer. The LACS protocol automatically scales the capacity with available connections (channels).

Figure 3-18 600 Mbit/s Ethernet Link

3.8.2 VCAT and LCAS support Evolution Series METRO supports virtual concatenation and LCAS according to (ITU-T G.7042/Y.1305). Four VC-groups are supported. The members of the VC-group must be of the same type. The following groups are available:

• VC-12 x n, where n=1..64 • VT1.5 x n, where n=1..64 • VC-3 x n, where n=1..12 • VC-4 x n, where n=1..4

The LCAS protocol implemented covers the following functions:

• Automatically temporary removal of a faulty VCAT member. • Automatically insertion of a temporary removed VCAT member when the fault is repaired.


3.8.3 Ethernet services The Ethernet Unit provides two types of E-line services. Either a port to ODU/XCVR tunnelling mode providing multiple E-Lines or a Switch mode with one WAN port and four LAN ports.

3.8.3.1 Multiple E-Line With port mapping each individual Ethernet port forms a separate channel through the link. Port mapping is achieved by using inserting a VLAN-tag on incoming traffic. This VLAN-tag is removed at the output-port.

• Each LAN port will be mapped to a given WAN (Virtual Container Group – VCG) • Traffic may be untagged or customer tagged – VLAN transparent • Up to four WAN port/links can be used. WAN capacity per port is scalable as described in

chapter 3.8.2. Aggregated WAN capacity is maximum 600 Mbit/s • QoS is supported on the aggregated traffic on the WAN port.

Figure 3-19 Port to Link Mapping - Multiple E-Line


35

3.8.3.2 E-Line with VLAN/MAC switching In switch mode the unit has one WAN port and four LAN ports. Each port can be defined to be member of a VLAN or a VLAN range. LAN ports will only accept packets with specified VLAN and packets will be forwarded to all port members of VLAN until MAC destination address is learned. The traffic can be untagged or customer tagged, in case of untagged the GbE switch can add defined tag value.

• WAN capacity is scalable from 2Mbit/s (1.5Mbit/s ANSI) to 600 Mbit/s. • The switch can be set to add/strip a user defined VLAN tag on the traffic on LAN ports • QoS is supported on WAN port.

Figure 3-20 VLAN Switch mode


3.8.4 QoS features. The QoS characteristics of the system will naturally be governed by the queuing and buffering strategies of the subsystems. To allow for a wide array of applications for this product these strategies are made user selectable.

3.8.4.1 QoS priority scheme Four traffic queues representing four priority levels are available. Traffic can be prioritised based on VLAN 802.1p, type of service or port.

1. VLAN (802.1p user priority) Priority level can be assigned based on VLAN user priority represented by 8 decimal values (0-7).

2. DSCP/TOS (IPv4/IPv6) Priority level can be assigned based on DSCP/TOS represented by 64 decimal values (0-63).

3. Port (Ethernet input ports) Priority level can be assigned to each port individually.

4. QoS priority OFF (Maximum throughput) All traffic has equal priority.

3.8.4.2 QoS scheduling mode The queues can be set up with either fair or strict queuing Fair queueing Fair queuing tries to distribute forwarding capacity between the different priority levels to prevent high priority data streams from completely blocking lower priority streams. Scheduling is done according to a fair weighting (8, 4, 2, 1) applied to the four priority queues. Strict queueing All top priority frames egress until that priority's queue is empty. Then the next lower priority queue's frames egress, etc. This ensures that all high priority frames egress as soon as possible.

3.8.5 Ingress rate limiting Per port ingress rate limiting with optional flow control is available and can be set independently of other settings. Drop mode can be configured to either continuous drop or burst drop. Flow Control uses pause frames.

3.8.6 Frame delay – Ethernet Interfaces Frame delay specified below is according to ITU-T Y.1563, Network Section and RFC 1242 store-and-forward definition: "The time interval starting when the last bit of the input frame reaches the input port and ending when the first bit of the output frame is seen on the output port." Numbers in the table below are given for a link with no queuing-delay and all link capacity allocated to Ethernet-traffic. Propagation delay excluded.

3.8.7 MAC learning MAC-learning can be enabled/disabled. MAC-table aging is configurable. MAC address table size is 8000.

3.8.8 Maximum Packet Size With port-mapping enabled, the equipment is transparent to packet-sizes up to 1628 bytes. With port-mapping disabled, the equipment is transparent to packet-sizes up to 1632 bytes.

3.8.9 Ethernet Statistics RMON statistics is implemented and counters can be read via the WEB interface or SNMP Manager

3.8.10 Typical Ethernet Throughput Ethernet throughput is measured according to RFC 2544. Throughput higher than channel bit-rate is achieved by removing Inter-Packet-Gap over the air. The Inter-Packet-Gap is then restored before the packets leave the IFU.

3.8.11 Link-Loss Failure pass through on the Ethernet port Evolution Series supports a Link-Loss Failure pass through, LLF. This is useful for routers or switches to detect that the Ethernet connection has failed or there is no pass through connection through the radio link side. The LLF function is based on the principle that the interface on the opposite side will be disconnected when the link on the Ethernet port or the radio link has failed. Hence, a failure situation will be communicated to either ends in the link configuration. When there is a radio link failure, the LLF function will control the Ethernet link on the opposite side of the radio link by the link status on each side. I.e. if the incoming Ethernet signal on one side is disconnected, the output on the Ethernet port on the opposite side will be turned off. LLF is not supported in Switch Mode.


4. XPAND SYSTEM DESCRIPTION

Evolution Series XPAND is a scalable hybrid Ethernet and PDH radio. Transmission capacity ranges from 6 Mbit/s to 150 Mbit/s. The transmission can be either E1&Ethernet based (ETSI) or T1&Ethernet based (ANSI). Option for STM-1/OC-3 user interface is available. Link Configurations are 1+0, 1+1/HSB and 1+1/HSD SD, see chapter 5 for details. The E1/T1 signals and the Ethernet traffic are mapped in to a scalable frame for radio transport. The frame has in addition to the main traffic a NERA overhead (NOH) with two 64 kb/s channels used for EOW or 64 kb/s user channel and a 192 kb/s out of band management channel (DCN).

Figure 4-1 Scalable frame

4.1 User Interfaces The Universal IFU can have following interfaces and plug-in units.

• Two or four 10/100 BASE-TX • 12xE1 and 25xE1 Units, 8xT1 and 16xT1 Units • 4x64 kb/s Unit • EOW and 2x64 kb/s Unit • Alarm and Control Unit • 155 Mbit/s electrical or optical interface Unit with DXC Unit including Sync interface.

Access IFUs with fixed interfaces and no PXC function are also available. See chapter 12.3 for more details. Access IFU can be mixed with Universal IFU both for TDM and Ethernet traffic.

4.2 Architecture and TDM Features The system with Universal IFU features an embedded PDH X-Connect (PXC). Two IFUs can be combined to a traffic node with 4 ODUs connected. (2 x HSB or 4 x Non Protected) Each of the PXC ports can be assigned to an E1/T1 Interface Unit, to an STM-1/OC-3 Interface, towards an ODU or to the IFU-rear-interface for connection to a second IFU. If Ethernet traffic from the SU is transported through the X-connect it will occupy one port.1 The capacity through the 4 PXC-ports is limited by the unit each port is connected to as shown in the table below:

PXC connected to: Maximum Capacity per port

E1 Line Interface 25E1 T1 Line Interface 16T1 Radio Interface 75E1 or 96T1 IFU rear Interface (IFU expansion) 75E1 or 96T1 STM-1/OC-3 Interface 63E1 or 84T1 Ethernet port (on SU Unit) 1 100 Mbit/s

Table 4-1 PXC Connections

Each of the E1/T1 carried through the 4 PXC-ports can be X-connected (any to any, non-blocking). Each E1/T1-output from the PXC can be configured to be sourced from any E1/T1-input. All E1/T1-outputs may have the same source (one-to-many principle). Four of the PXC-ports can be configured to go to Radio Interfaces. SNCP is available for each E1/T1. When configuring the PXC, each individual E1/T1 may be set up with SNCP activated or not activated.

One IFU has four ports available, maximum two for RIU and two or three for LIUs. When two IFUs are used together there are six ports available. RIUs working in HSB mode occupy only one port in the PXC.

4.2.1 SDH/SONET connection E1 or T1 signals can be mapped into a STM-1/OC-3 frame also in XPAND mode. This can be very useful if many E1/T1s needs to be brought to a central point for connection to a SDH/SONET network or simply used as an interface to other equipment with STM-1/OC-3 interface. A DXC unit is needed which also features the SETS function.

4.3 Ethernet functionality

4.3.1 General The Supervisory Unit on the Universal IFU and the Access IFUs has Fast Ethernet interfaces for management and user traffic. For the universal IFU there are two main types of SU with either two or four FE ports. On the Universal IFU the ports(s) can be separated for management and user traffic or the management traffic can go inband with the user traffic. The unit with four ports (SU-D) has support for a separate management VLAN, VLAN switching and QoS. The Access IFU has separate ports for management and traffic.

4.3.2 Ethernet Traffic Mapping Ethernet traffic is mapped directly into the radio frame using a proprietary method. As the frame can also transport E1 or T1 channels the capacity is scalable in steps of E1 or T1s.

4.3.3 MAC (IEEE 802-1D) and VLAN (IEEE 802.1-Q) switching In switch mode the unit has one WAN port and two or four LAN ports depending on unit. The Access IFU has separate switches for user traffic and management traffic.

4.3.4 MAC learning MAC-learning can be enabled/disabled. MAC-table aging is configurable. MAC address table size is 2000.

4.3.4.1 VLAN functions A port can be defined to be member of a VLAN or a VLAN range. Both LAN ports and the WAN port can be defined as untagged or tagged, in case of untagged the switch will add a VLAN tag with the defined value on ingress and remove the VLAN tag from egress traffic. In case the port is defined as tagged, the port will only accept packets with the specified VLAN id and packets will be forwarded to all port members of that VLAN until MAC destination address is learned.

• WAN capacity is scalable from 2Mbit/s (1.5Mbit/s ANSI) to 100 Mbit/s. • QoS with selectable criteria is supported on the WAN port.

4.3.5.1 QoS priority scheme Four traffic queues representing four priority levels are available. Traffic can be prioritised based on the list below. The user can configure which queue the various service types (values) shall be mapped to.

1. VLAN PCP (802.1p user priority) Priority level can be assigned based on VLAN user priority represented by 8 decimal values (0-7).

2. DSCP/TOS (IPv4/IPv6) Priority level can be assigned based on DSCP/TOS represented by 64 decimal values (0-63).

They examples are based on METRO terminals with STM-1/OC-3 interface but the main architecture is valid for both XPAND and METRO modes. The IFU part will be different depending on number of interfaces and directions. Most configurations are described for a split mount system with ODU, but can also be implemented with long haul optimized RF-branching and XCVR. The ODU is then replaced by a branching and XCVR(s). A system with RF-branching is described in chapter 5.9

5.2 1+0 system The 1+0 configuration consists of an IFU basic frame, a Line Interface Unit, a Radio Interface Unit, a single coaxial cable to the ODU and an ODU mounted directly on the antenna or near the antenna. When the ODU is not mounted directly on the antenna, a short flexible waveguide is used to connect the ODU to the antenna port.

5.3 1+1 HSB / 1+1 FD system The 1+1 HSB or 1+1 Frequency Diversity configuration, consist of an IFU basic frame, a Line Interface Unit, two Radio Interface Units, two coaxial cables to the ODUs and two ODUs mounted on an RF-Coupler Unit. The RF-Coupler can be asymmetrical or symmetrical, and the RF-Coupler/ODU assembly can be mounted directly on the antenna or near the antenna. When the RF-Coupler is not directly mounted, a short flexible waveguide is used to connect the RF-Coupler to the antenna port. In a 1+1 FD configuration both ODUs must be in the same subband.

5.4 2+0 / 1+1 HSB Dual Baseband system A 2+0 system or 1+1 HSB Dual Baseband is identical to the 1+1 HSB or 1+1 Frequency Diversity configuration except for the use of two Interface units. The two LIUs provide interface protection in HSB configuration. HSB Dual Baseband is applicable for STM-1/OC-3 Line Interfaces only. In a 2+0 configuration both ODUs must be in the same subband.

5.5 Space Diversity/Dual Antenna system The 1+1 HSB or 1+1 Frequency Diversity configuration can be configured for Space Diversity or Dual Antenna. This configuration uses two antennas, and the two ODUs are mounted one on each antenna without using an RF-Coupler. The use of Space Diversity/Dual Antenna reduces the RF loss and provides path diversity, which can improve system performance (subject to frequency band and path type and length).

5.6 Co-channel Dual Polarised (CCDP) system In two channel systems the two ODUs can be arranged with dual polarisation (Horizontal and Vertical), utilising a single RF frequency. The RIU contains a XPIC function in this configuration, and the XPIC will handle the interference between the two received signals. See also paragraph 7.5 for further description of the XPIC function.

5.9 7+1/8+0 System Long Haul Optimized The Long Haul Optimized system uses a low loss RF-branching system combining up to 10 channels to one antenna port. The Branching system contains narrow band RF-filters for each channel, connecting the channels together. The branching system can also be split for transmission on both polarisations. In Space Diversity configuration, two receive branchings are used in parallel connecting the two antennas to two receivers inputs for each channel. The received signals are combined in-phase in the transceiver unit. See also Figure 6-2.

9.7 System characteristics for Space Diversity (SD)

9.7.1 General A Space Diversity system includes a Space Diversity transceiver unit, which contains one transmitter and two receivers. The control functions are included in the transceiver unit.

9.7.2 Combining principles and performance The combining method is in-phase IF-combining. The effect of this combining is an improvement of the receiver threshold in fading situations when input levels are low. The improvement is at least 2.5 dB for signals of the same level at an arbitrary phase difference Maximum difference of wave-guide lengths between main and diversity antennas is 30 meters for a standard space transceiver. An additional 30 meters is offered as an option. The static delay compensation is automatically adjusted during system installation via the Web interface. External delay compensation or external instruments are not needed.

12. UNIT DESCRIPTIONS

12.1 Transceiver (XCVR) and OutDoor Unit (ODU) The XCVR and ODU hardware is capacity and modulation independent. The XCVR consists of the Transmitter and the Receiver and it is tuneable over the whole frequency band, both high and low part. Two XCVR variants are available Standard Power and High Power.

XCVR Type 4, 5 and 10 GHz L6, U6, 7, 8 and 11 GHz 13-38 GHz

Standard Power - x x High Power x x - High Power SD x x The high power XCVR Unit is used as a standalone unit in the long haul systems with RF branching. Standard power XCVR can also be used with RF branching. The ODU consists of a XCVR and a Diplexer, where the diplexer determines the sub-band coverage. The diplexer is a detachable unit which can be used with both high and low subband as transmitter subband. The change of high low is simply done by turning the diplexer 180 degrees. The ODU is normally mounted directly to the antenna for all configurations. In HSB and 1+1/2+0 configurations an RF-Coupler is used when connecting the ODU to the antenna interface. An optional pole mount kit is also available.

Figure 12-1 XCVR and ODU


12.2 Universal Interface Unit (IFU) The Evolution Series IFU is a 1RU high modular unit, containing 9 plug-in slots for various units. The modular architecture with plug-in slots enables a high degree of flexibility, ease of upgrading/changing configurations and easy maintenance.

Figure 12-2 IFU, 1+0 system

The basic IFU frame is common in all configurations and up to four basic IFU frames and one DXC frame (optional) be stacked together by a rear mounted IFU connection panel. - The lower left position (1) contains the Supervisory Unit. The Supervisory Unit is handling the

configuration of all system units as well as reporting system status to the EM/NMS system. The unit also has an Ethernet switch with interfaces both for user traffic and management.

- The rightmost position (6) houses the FAN Unit, handling the ventilation and temperature management of the IFU frame.

- Line Interface units can be placed in slots 1-5 depending on system configuration. The 25E1, 16T1 and Ethernet traffic interfaces are full height and covers the upper Aux/Serv. position as well. The Gigabit Ethernet Unit must be placed in slot 3 if mapping to more than one 155 Mb/s is required.

- The DXC Unit must be placed in slot 3. The DXC units contain the SETS function and external synchronisation interface.

- The Radio Interface units and Power Supply Unit must be placed in slot 4 or 5. The RIU provides connection to the ODU/XCVR and includes power supply to the IFU and the ODU/XCVR. The Power Supply Unit is used in IFUs without RIU.

- The upper Aux/Serv. slots (7, 8 and 9) house any Auxiliary or Service Channel units, such as Alarm and Control Unit, Wayside Unit, 64 kb Data Channels Unit and EOW Unit. Slot 8 and 9 can house 24 volt adapter

All units can be replaced in the field. Non traffic carrying units can be replaced without interrupting the service. See paragraph 12 for further description of the various plug-in units.

12.3 Access IFUs The Access IFUs are 1RU units, containing supervisory unit and fixed interfaces for E1/T1, Ethernet, Management traffic and 64 kb/s. See Table 12-1 for versions. The IFUs can have one or two radio interface units, for 1+0 or 1+1/HSB configuration. The radio interface unit is the same used with the Universal IFU and Access IFUs are compatible over the hop with the Universal IFU in XPAND mode.

12.4 Supervisory Unit The Supervisory Unit is handling the configuration of all the system units as well as reporting system status to the EM/NMS system. It has two or four 10/100 BASE-TX Ethernet ports for user and management traffic.

The first versions of the unit (A, B and C) have two Ethernet ports and two USB ports.

The latest version of the SU (D) has four Ethernet ports and no USB ports.

User Traffic

In XPAND the SU has the user Ethernet interface and the traffic is mapped directly in to the radio frame together with E1/T1s.

In METRO mode user traffic is either mapped into the 2 Mbit/s Wayside channel in the SOH or into a STM-1/OC-3 channel. See chapter 15.2 for an example. For METRO a Gigabit Ethernet Unit is also available. See 12.6.5

Management

The ports are connected to an internal switch and can both be used for connection to the EM/NMS system and/or for connecting terminals together in a Management LAN/DCN.

An internal OSFP/RIP router handles routing of out of band management traffic. See chapter 16.5

15. RADIO PROTECTION SWITCHING (RPS)

15.1 General In order to facilitate switching without introducing bit-errors, a hitless switching system is provided. The Radio Protection Switching function is used in HSB and n+1 Frequency Diversity configurations. Automatic and manual switching is available. The manual switching can be hitless or forced and is performed from the WEB Interface. In Hot Standby configurations the TX- and RX- switching at a terminal normally operates independently, but they may be configured to operate together.

15.2 Low Priority Traffic In METRO mode the protection channel can be utilized with low priority traffic. It can be configured with STM-1/OC-4 LIU, Gigabit Ethernet Interface Unit or with 100 Mbit/s Ethernet using the Ethernet Mapper at the Supervisory Unit.

15.3 Base band switching operations The protection switching equipment automatically replaces a faulty channel by the standby channel at traffic disturbance. All channels can be enabled/disabled for different maintenance purposes.

15.4 Switching capability The Radio Protection Switching function is capable to handle system configurations up to 7+1.

15.5 Priority of protection switching The following is only relevant for N+1 systems where N>1: The protection switching equipment is provided with facilities for setting the priority of any radio channel by means of local or remote control through the built-in supervisory system. Indication of relevant status is provided, both for local control and remote supervision. Each radio channel can be set up with different priority.

15.6 Alignment specification Automatic synchronization of the incoming digital signals is performed before switching takes place. The alignment is based on bit-aligning of the datastream. • Dynamic range: ±50 bit

15.7 Switching criteria, Rx

15.7.1 Continuity criteria The continuity criteria are determined by the Out Of Frame (OOF) signal. • Detection time OOF 5 x 125 µs = 625 µs • Rx Alarm IFU (LOF, LOC)


99

15.7.2 Quality criteria A quality criterion is determined by overrun of pre-set limits. For a quality criterion, three thresholds are considered as limits for switching operation. Each criterion can be set to different Bit Error Rate levels by the supervision system: • HBER - Bit Error Rate exceeds a value of approx. 10-3 (default) • LBER - Bit Error Rate exceeds a value of approx. 10-6 (default) • EW - Bit Error Rate exceeds a value of approx. 10-10 (default) • Low_RF - Receiver RF input level is below a set threshold. The BER quality criteria are based on signal to noise ratio.

15.8 Switching operation time, Rx The alarm detection time for BER will strongly depend on the severity of the channel disturbance. BER = 10-5 detection-time will be <1 ms if a degradation that will cause a bit-error rate of 10-4 or worse is detected. A table giving approximate detection times at different bit-error-rates is given below. The detection time will depend on the selected threshold for the different criteria:

Actual Switching Criteria Detection Time for Different Thresholds [ms] BER 10-3 10-4 10-5 10-6 10-7 10-8 10-9 10-10 10-11 10-12 1x10-3 1-2 0.4 -0.8 0.15 - 0.30 0.44 - 0.89 0.18 –

The different BER criteria, HBER, LBER and Early Warning (EW), can be selected from the table above. The only restriction is: HBER > LBER > EW. A processing and communication time is added to the criteria detection time to get the total switching operation time. The Communication and Processing time depends on system type and is given below: • 1+1 Radio Protection Systems (without Low Priority Traffic): < 5 ms • N+1 Radio Protection Systems (including 1+1 with Low Priority Traffic): < 10 ms If switching is initiated in both directions at the same time, this can increase the total switching operation time slightly.

16. MANAGEMENT SYSTEM CHARACTERISTICS

16.1 General The powerful integrated supervisory system of Evolution Series provides user-access to the NEs in a most dynamic manner. The management function in the NE can be accessed by the use of a web-browser, Command Line Interface (CLI) or by a SNMP manager such as the NERAs management system NetMaster. The management traffic is IP protocol based.

Note 1: Configuration from CLI is limited. A NE is controlling all the units connected to a specific node with a common supervisory unit. The NE software performs the following management tasks: Fault management: Collecting and logging of alarms and analogue measurements from the

management units connected to the Node. Performance management: Collecting and logging quality measurements according to standards

(G.784) Configuration management: Configuration of node (including configuration up/download) and

Software download Security management: Configuration of user id/password and the users privileges in the NE.

Includes logging in NE of user actions.

16.2 Event logging Evolution Series NEs can log events and faults in the local fault log. The log size is 10.000 events. The log can be set to wrap-around or halt when it is full. Alarm logging can be masked based on severity level. An operator (with administrator privileges) can also clear the log.


101

16.3 Monitoring of system performance Transmission performance data is monitored continuously by the built-in supervision function. The supervision function performs measurements and calculations based on the parity bits in the SOH/TOH for METRO or parity bits in each E1/T1 for XPAND. Traffic bit error rate information from the modem is also available. At the Ethernet layer RMON statistics is used.

16.3.1 System performance calculations Performance data are based on the ITU-T Rec. G.826 system performance parameters. The following system quality calculations are included:

• Error Second Ratio (ESR) • Severely Error Second Ratio (SESR) • Background Block Error Ratio (BBER) • Unavailable state (UAS)

16.3.2 Performance record logging Performance logging can be activated for individual signals, one at a time. 15-min, 24-hour and month records are calculated. The log contains the current and last month, current and last 24-hour and current and the sixteen last 15-min records. Threshold values can be defined each of the performance records and a performance alarm will be raised if the threshold is exceeded for any of the periods. In addition cumulative error counters for parity pulses are available. The operator can read and reset the counters.

16.4 Security management The user must have a username and password defined in the NE in order to log in. Each user name is defined with access privileges. Four levels are defined; User level Privileges Passive Users Passive users are only able to monitor data. They are not able to change any

configuration. Active Users Same as Passive. In addition active users are able to reset counters. Master Users Master users have access to all commands, except those related to user account

administration and Configuration/SW download. Admin Users Admin users have access to all commands. The Admin user is the administrator and is

responsible for adding, deleting and managing user accounts and privileges. In addition the admin user is responsible for Configuration/SW download.

16.4.1 Security event logging The NE can log events related to security. The log size is 1000 events. When it is full it will wrap-around. The operator (with administrator privileges) can also clear the log.


16.5 Management system communication Access to the management is from the Ethernet port(s) at the SU. The SU can be set up with one or two dedicated ports for management access. The management traffic to other terminals is transmitted over the DCC channel in the NOH and the IP router handles the routing An alternative is to use the Ethernet switch in the SU and transport the management traffic inband with the user traffic. SU version D has VLAN support and a dedicated VLAN can be used for management traffic.

16.5.1 Management LAN interface Two 10/100BASE-TX interfaces, IEEE 802.3 Full Duplex. Connector type: RJ-45

16.5.2 USB interface The USB host port serves as LCT interface. Available at SU versions A, B and C.

16.6 IP routing The routing function enables routing of TCP/IP and UDP/IP traffic between the management module of the NE, the Management Ethernet interface, the DCC channels and the 64 kb/s PtP channels. The routing protocol used is OSPF/RIP2. Both Evolution Series management traffic as well as other telecom equipment IP based management protocols can be routed. There are both external and internal interfaces to the management module. The internal interfaces are used in a DCN to create communication links between NEs and/or the management centre/network operator.

16.6.1 Data Communication Channel DCC Each radio frame contains a dedicated DCC channel for communication with the remote site. The capacity of the DCC channel is 192 kb/s. In an n+0 or n+1 configuration the DCC is transported on Ch 1 and Ch2/p

16.6.2 64 kb/s point to point channels 64 kb/s channels can be used to set up communication links between terminals without direct connection. They can also be used to make direct overhead connections to remote sites. This can be useful in a large network to avoid long routing paths. The feature requires 64 kb/s adapter. The following options are possible.

• 64 kb/s channel in overhead byte towards radio • 64 kb/s channel in overhead byte towards STM-1/OC-3 Line • 64 kb/s external channel

16.6.3 DCN network In this network the management traffic is logically and if needed also physically separated from the user traffic. Figure 16-2 illustrates use of the different communication channels is the network.

16.7 Inband Management Access to management can be configured inband with main Ethernet traffic. In XPAND this is enabled by using the Ethernet Switch in the SU. The management traffic will then be transmitted inband with the user traffic. SU version D supports VLAN switching and management traffic can then be separated on a separate VLAN. For METRO the Ethernet Wayside channel can be used for management traffic in this mode or a connection between SU and GBE Unit is required.
