4 COMMISSIONING VIA LCTThis Chapter lists all the configuration and activation operations which must be executed
via LCT for the commissioning of the equipment.
The sequence of the operations is described in tabular format by means of a
step-by-step procedure; for each operation, the heading of the table (box in the top right
part of the title) indicates the paragraph of the operating guide, which it is necessary to
refer to, in order to get more details.
Before starting the commissioning procedure, execute the following preliminary
operation:
Connect the LCT terminal to the F interface or the Q/V Ethernet interface of the
equipment.
Verify that the memory hardware key is inserted, before starting-up the equipment.
The IDU Plug-in is provided with a memory hardware key, which stores the equipment
configuration to allow an easy and fast replacement of the Controller.
The hardware memory key has the following characteristics:
it is the backup key of the equipment configuration, each change of a configuration
parameter is stored in the non volatile memory of the Controller and, immediately,
also in the non volatile memory (EEPROM) of the hardware key
it is identified by:
serial number, which is univocal equipment type which it has been configured for
The following IP addresses are assigned by default in factory to the interfaces of
SRAL XD:
Q/V Ethernet interface:
IP address: 10.10.10.10
Net-Mask: 255.255.255.0

after the start-up, it is strictly associated to the equipment Controller (the controller
memorizes the hardware key serial number)
it contains the license; each hardware key delivered with the equipment contains
the license ordered by the Customer.Also the management of the System Type unknown is foreseen; it is a temporary
condition of the equipment that can occur in the following cases:
when the upgrading of the SVR is required, to manage a System Type not
supported by the current SVR
during the acquisition of the content of the hardware key, in order to solve the
possible mismatch commands.
Diagnostics for the hardware key
The following diagnostic signals are available via software for the hardware key:
Disconnected status signal
Condition of disconnected hardware key; the system detects the physical
availability of the hardware key through polling (devoted sense pin). If the condition
of disconnected hardware key is present at the equipment start up, the Controller
switches to the IDLE status; vice versa, if this condition occurs with the equipment
on, the Controller switches to the RUN/NO SET status.
Mismatch status signal
The hardware key is not congruent with the equipment type. This condition is
present when the user inserts, by mistake, the hardware key relevant to a different
equipment type. If at the start up of the equipment, the condition of not congruent
hardware key is present, the Controller switches to the IDLE status; vice versa, if
this condition occurs when the equipment is switched on, the Controller switches
to the RUN/NO SET status.
Key E2prom Fail Alarm
The EEPROM of the hardware key is out of order; in this situation, the hardware
key can not be accessed.If the Key E2prom Fail alarm is present at the equipment start up, the Controller
switches to the IDLE status and the equipment configuration stored in the
non-volatile memory of the Controller is loaded; vice versa, if the alarm occurs
when the equipment is switched on, the Controller switches to the RUN/NO SET
status.
Alignment Fail Alarm
The serial number of the hardware key is different from the one memorized into the
Controller at the start-up. When the Alignment Fail Alarm occurs, the Controller
switches to the RUN/NO SET status. This condition can be present only when the
equipment is turned on, the user extracts the hardware key present at the power-on
time and inserts an hardware key configured for the same type of equipment.
Starting from SVR 3.6, a new management modality of the memory hardware key
is foreseen.
In case of downgrading of a SVR 3.6 equipment to a previous SVR 3.6 or higher,it is necessary to execute the defrag of the hardware key, in order to allow a
possible successive upgrading to SVR higher without problems.

Controller status
The equipment Controller can assume one of the following operating statuses:
RUN/SET
The internal (towards the slaves) and external interfaces are enabled; the systemcan execute the configuration operations (within the limits foreseen by the license
and by the user class). This is the normal operating condition.
RUN/NO SET
The internal (towards the slaves) and external interfaces are enabled but the user
can execute reading only operations. In this condition, the F interface is still
operative to allow the download of the equipment software. This situation is present
when the equipment is turned on and the user extracts the memory key or there is
an alarm condition on the hardware key.
IDLE
The internal interfaces (towards the slaves) are disabled while the external onesare enabled (the system does not display queries of the slaves). In this condition,
the F interface is still operative to allow the download of the equipment software.
This situation is present in the following cases:
the equipment is switched on without hardware key inserted
the equipment is switched on, but the inserted hardware key is faulted or not
congruent
the System Type present in the configuration of the hardware key is not
supported (condition of System Type unknown).
Start-up of the Controller
At start-up, the Controller executes a series of controls on the hardware key:
if the hardware key is not connected, the signalling of Disconnected hardware key
activates and the Controller switches to the IDLE status
if the hardware key is out-of-order, the alarm signalling of Key E2prom Fail
activates and the Controller switches to the IDLE status
if the configuration stored in the hardware key is not congruent with the equipment
type, the signalling of Mismatch hardware key and the Controller switches to the
IDLE status
if all the checks on the hardware key are OK (hardware key is connected,
congruent, properly operating and acknowledged as equipment hardware key,
System Type supported), the equipment configuration and the licenses contained
in the hardware key are loaded and the Controller stores the serial number of the
hardware key and switches to the RUN/SET status.
In the following flow diagram, the management of the hardware key during the
switching-on phase of the equipment or after a command of software reset of the
Controller is displayed.

Run-time operation of the Controller
During the normal run-time operation:
the Controller is in the RUN/SET status if the hardware key is On Line and without
alarms
the Controller is in the RUN/NO SET status if an alarm condition of the hardware
key is present (Mismatch, Disconnected, Alignment Fail, Key E2prom Fail); in this
condition, the Controller is enabled only to maintain the configuration in its volatile
memory.
In the following flow diagram, the conditions which determine the passage of the
Controller from the RUN/SET status to the RUN/NO SET status are illustrated.

Extraction/replacement of the hardware key
The hardware key must be always connected to the IDU Plug-in during the normal
operation of the equipment.
The key extraction is allowed only for the corrective operations following.
In case of replacement/repairing of the faulted IDU, the procedure is the following:
remove the hardware key that contains the equipment configuration and the
current license, before executing the replacement/repairing of the IDU
insert again the hardware key, after the replacement/repair of the IDU, beforeswitching on again the equipment
at start-up, if all the checks are OK, the equipment configuration and the license
stored in the hardware keys, which are the same of those present before the
intervention of corrective maintenance, are loaded.
In case of fault of the hardware key provided with the equipment, the same can be
provided as spare parts.
For the codes of the licenses to require the spare hardware key, refer to the UMN
manual of the equipment.
The insertion of the spare hardware key, as replacement of the faulted hardware
key, causes the activation of the Key E2prom Fail alarm, which can be clearedonly by switching off and, then, switching on the IDU, with consequent loss of
traffic and loss of the configuration (the equipment restarts with the default
configuration that is loaded at the first start-up of the equipment)

lower than the maximum value allowed for the HD density
to modify the ATPC management range (ATPC Range), currently set for the ND density, in such a way that
it is congruent with the maximum value of RF TX power allowed for the HD density; this operation must be
executed even if the ATPC management of the RF TX power is disabled.
Naturally, all the other conditions that enable the use of the HD density must be satisfied.

Click on Tx Power Setting to open the window for the configuration of the RF TX power.
Disable the ATPC management (ATPC ManagementDisabled). Set the value of the RF TX power (RF
Tx Power), which must be between the allowed minimum and the maximum value. In case of (1+1)
Hot-Standby configuration, set the value of the coupling loss (Coupling Loss); the value to set depends on
the type of used frame (from 0 to 15 dB). For both the ODUs, the same value must be set.
Step 8A Configuration of HD/HDe Type ODU par. 5.5.1.9
On both the terminals of a radio link the same modality of management of the RF TX powermust be used (both the terminals with ATPC management or both the terminals with RF TX
power fixed).
For ODU HD/HDe, independently from the management modality which will be used, it is
necessary to configure both the value of rated fixed RF TX power (RF TX Power parameter)
and the minimum value of RF TX power of ATPC (P-min ATPC parameter) in order to avoid
conflicts and/or malfunctions.
The max. value of RF TX power depends on the channel density of the ODU (HD or ND).
For the 26 GHz range, the performance data are not ensured when the ODU works in HD
modality with radio capacity 8xE1 and the RF TX power is greater than 13 dBm.

In case of configuration of the RF TX power with ATPC management, the ATPC management
must be activated and configured both on the local terminal and on the remote terminal.
In order to avoid conflicts and/or malfunctions, it is necessary to correctly configure the
P-min ATPC parameter even if the ATPC management of RF TX power is not used.

Bridge functioning modalityThe parameters to be configured are the following: Bridging Mode
It allows selecting the modality used by the bridge for the routing of the frames received in input from the
LAN and Trunk ports.
Four different operating modalities are present:
Normal bridging: Fully connected LAN ports
Each frame in input is routed on the basis of the destination MAC address and the LAN ports are fully
interconnected (the frames in input from a LAN port can be sent to any other port, without no restriction).
Normal bridging: Isolated LAN ports
Each frame in input is routed on the basis of the destination MAC address and the LAN ports are isolated
(the frames in input from a LAN port can be sent only to the Trunk port).
VLAN bridging: Selective VLAN forwarding
The frames in input from a port are routed on the basis of the VLAN ID which they contain. Only thepassage of frame that contain a VLAN tag with value of VLAN ID included in the list of the VLAN IDs
associated to the port is allowed
VLAN bridging: Uplink VLAN tagging & replacing
In each frame in input from a LAN port containing or not a VLAN tag, a tag is inserted with VLAN ID equal
to that associated to the input port
Priority Scheme
It allows selecting the priority scheme used by the bridge to send the frames in output.
Two different priority schemes are present
Fixed Priority
The frames with highest priority are always transmitted as first.
WFQThe transmission of the frame is executed by means of four queues of different weight, each one
associated to a different priority level.
Age time of MAC Address
It allows setting the age time during which a MAC address remains stored in the MAC DB, starting from the
moment when the last frame containing as source this MAC address; once the age time is expired, if in the
meanwhile no other frame has been received containing as source this MAC address, the MAC address is
deleted from the MAC DB.
The age time can be set at steps of 16 seconds and it is calculated multiplying by 16 the set value.

1 Priority
2 Priority
3 Priority (highest priority level)
The frames in input to the Trunk port are always assigned with the highest priority level (3 Priority), in order toavoid the possibility that these frames can be discarded.The parameters to be configured for the priority level to be assigned to the LAN port input frame are thefollowing: 802.1P Priority Table
If for one of more LAN ports is enabled the assignment of the priority level, configure the 802.1p Priority table
according to the value of the User Priority field of the VLAN tag contained in the frame in input to the LANport.
A single 802.1p Priority table is foreseen, whose configuration is valid for all the four LAN ports.

LAN Priority
On each Ethernet LAN port used for traffic transport it is necessary to configure the rules of priority levelassignment to the input frames of the LAN port.
802.1p Priority: the criterion can be enabled or disabled for each single LAN port
IP Priority: the criterion can be enabled or disabled for each single LAN port
Default Priority: for each LAN port, it is possible to select the priority level to assign to the frames in input
to the bridge of the LAN port; the criterion is always enabled for all the four LAN ports.
For a LAN port, the Default Priority criterion is used in the following cases:
no other criterion is enabled for the LAN port
a possible other priority criterion enabled for the LAN port cannot be applied to the frames in input (e.g.:
the IP Prioritycriterion is enabled and the packets in input are not of IP type).
If on a LAN port both criteria 802.1p Priority and IP Priority are enabled, it is necessary to specify the first
criterion to be used to assign the priority level to the input frame (802.1p IP Priority).
In case of VLAN bridging: Uplink VLAN tagging and replacing modality, set the value of the third bit of theUser Priority field (802.1p LSB) contained in the VLAN tag that is inserted in the frame in input from the LAN
port; the other two bits of the User Priority field are determined on the basis of the priority level associated
to the frames in input.

bidirectional unprotected connection of an external tributary on Access side with a radio tributary BB side
(functionalty available for all the System Type)
bidirectional unprotected repeater connection (functionality available only with System Type A/D-Rep).

In case of DATA Access unit, the available tributary interfaces in the cross-connection matrix are the following: TRIB i/f: external tributary interface
8xE1 external tributaries are available.
The external tributaries are identified by the Tr code followed by the tributary number (e.g.: Tr #1).
RADIO i/f: radio tributary interface.
The number of available radio tributaries depends on the on air radio capacity set for the radio system
(max. 16xE1 radio tributaries).
The radio tributaries are identified by the R wording followed by the tributary number (e.g.: R#1).
DATA E1 i/f: Ethernet tributary interface.
16 E1 tributary ports are available on the Trunk port of the bridge for the transmission of the traffic on
Ethernet LAN network.
The Ethernet tributaries are identified only by the tributary number (e.g.: #1).
The allowed cross-connections are between:
radio tributaries and external tributaries radio tributaries and Ethernet tributaries
No cross-connection is allowed between Ethernet tributaries and external tributaries and no loopcross-connection is allowed between tributaries of the same interface.The cross-connections on the Ethernet tributaries must be created starting from the first tributary (tributary #1)and following to the next tributaries.A cross-connection is active when the relevant tributary cross-connected on user side is enabled (externaltributary or Ethernet tributary).When it is necessary to set the traffic capacity to be used on the Ethernet interface (Data Capacity).For the traffic capacity of the Ethernet interface, also the 0xE1 value (default value) is foreseen, whichrepresents the condition of Ethernet interface not used for the traffic transport.The enabling of the Ethernet tributaries depend on the traffic capacity set for the Ethernet tributary interface; an

Open the Status and ConfigNetworkNE Parameters window.Select the RIPv1 protocol and open the Interface Parameters window, by clicking on Details push-button.Set the parameters of the network interfaces of the equipment; they must be assigned by the networkadministrator according to the planning of the supervision network.For each network interface, it is necessary to set the following parameters: Network Protocol: it is the network protocol of the interface:
for the F interface, the configuration options of the network protocol are:
IP SRA L Disable: support only of the connection to LCT
IP (default option): support both of the connection to LCT and the point-point connection with an
equipment of the SRA L family.
for the V-bus interface, the configuration options of the network protocol are:
None: disabled interface
IP SRA L Compatible: interface enabled with the IP protocol on proprietary HDLC; it must be set in
case of direct connection with an equipment of the SRA L family for the Q/V interface, the configuration options of the network protocol are:
None: disabled interface
IP: interface enabled with IP protocol on PPP and PPP on standard HDLC.
for the R and D interfaces, the configuration options of the network protocol are:
None: disable interface
IP: interface enabled with IP protocol on PPP and PPP on standard HDLC
IP SRA L Compatible: IP on proprietary HDLC; it must be set in case of direct connection with an
equipment of the SRA L family.
RIPv1 Enable: option for enabling of the interface as support of the RIPv1 routing protocol; with this option
disabled, all the other routing options are not meaningful.
RIPv1 Silent: option of RIPv1 protocol squelched in output from the interface.
Static Route Propagation: option of propagation of all the static routing information through the interface. Border Gateway: option of esclusion of the subnetwork information in the routing tables propagated through
the interface.
Ingress Summarization: option of resolution of the IP addresses contained in the routing tables received
through the interface:
with enabled option, the IP addresses are seen as network/subnetwork addresses
with disabled option, the IP addresses are seen as host addresses.
Metric Override: option of forcing of the metric reset.
The V-bus and Q/V interfaces are in alternative. The enabling of the V-bus interface involves
the automatic disabling of the Q/V interface and viceversa.
In case of use of the V-bus interface, it is suggested to physically disconnect the Q/Vinterface.
It is necessary to disable the Ethernet Q/V interface (None option) when the F interface is
used for the connection to a SRA L in the same IP subnetwork.
