Executive Summary GENBAND’s Local Session Controller (LCS) solution provides a cost-effective migration and modernization option for legacy Nortel PBXs. The solution protects and extends previous Nortel investments and simplifies the introduction of new IP-based endpoints and Unified Capabilities (UC). The solution has been tested and certified by the DoD Joint Interoperability Test Center (JITC).

This paper explains how GENBAND acquired certain Nortel assets, reviews the GENBAND LCS solution, and details the solution configurations and components tested at the JITC. It is intended for DoD agencies, defense contractors and other IT professionals who are investigating or planning technology refresh options and UC initiatives for legacy Nortel PBXs.

About GENBAND GENBAND is a privately held corporation headquartered in Plano, Texas. Started as General Broadband, the company was founded on the delivery of media gateways, and grew into a multi-million dollar telecommunications firm. In 2010 GENBAND acquired Nortel Networks’ carrier group. With the breakup of Nortel, GENBAND purchased a significant portfolio of products and intellectual property rights, including the CS 2000 and DMS switches that make up about half of the PSTN in North America. As part of that acquisition GENBAND also acquired support for the CS2100 and older SL-100 systems that are widely deployed in the U.S. Department of Defense (as well as by civilian agencies). Avaya acquired Nortel’s enterprise PBX business including the Meridian, CS 1000, and Norstar portfolios. Some of the technology had common origins and was shared by the two acquiring entities.

Figure 1 captures some of the technology and intellectual property that is relevant to the DoD and how it was split between GENBAND and Avaya.

As part of the break-up both organizations obtained legal rights to the Application Server (AS) 5300 R2 code and maintained some shared rights to the CS2100 and SL-100 portfolios. Since the original acquisition, GENBAND has acquired the majority of the intellectual property rights associated with the SL-100 and CS2100 technology still in use within the DoD. In addition, it has invested several million dollars extending the original AS 5300 Rel 2 code into the company’s primary SIP Application Server. (The platform is now called the GENBAND Application Server. It is sometimes also referred to as EXPERiUS or A2).

Today, the GENBAND AS maintains the AS 5300 heritage, plus has been enhanced to provide a fully virtualized solution that is architected to meet the needs of global service providers. The platform delivers five “9’s” reliability and scales to support millions of concurrent calls. This enhanced solution (now at Rel. 11.2 and soon to be at 12.0) was tested and certified at the DoD JITC.

DoD Deployment Examples GENBAND pursued LSC JITC certification primarily to support technology refresh options for legacy Nortel PBXs (i.e. SL-100, CS2100, AS 5300 CM1000M, etc.) on military base, post, camp and stations. The GENBAND LSC solution supports both legacy analog stations (and analog station requirements associated with fire alarms and other SCADA sensors) as well as new assured and non-assured IP phones and softphones clients for DoD workstations and laptops.

GENBAND’s LSC solution simplifies migration of legacy AS 5300 deployments. Because of the shared heritage of the legacy AS 5300 and the GENBAND AS, many aspects of the solutions will be familiar (and in some cases identical) for technical staff and end-users. This provides a compelling transition option for DoD organizations looking for a cost-effective way to migrate aging IBM servers and legacy Nortel software. GENBAND’s solution minimizes costs and disruptions while enabling new services and assuring on-going support.

Figure 2: SL-100 & CS2100 Migration – Footprint Savings

Another real-world example of a technology upgrade is the legacy SL-100 and CS2100 systems still in service within the DoD performing as either a Multi-Function Softswitch or End Office providing telephone (analog, digital and ISDN) for individual bases. By introducing GENBAND LSC, a significant number of the legacy SL-100 or CS2100 frames can be removed, reducing space and power expenses while protecting previous investments. Figure 2 depicts a base communications office upgrade.

In “green field” situations, the GENBAND LSC can be deployed in a dedicated server configuration, or as part of a Virtual Machine environment. With either variant the core servers are implemented in a 1+1 configuration for seamless failover, and can be physically separated to meet DoD Coordination of Operations Planning objectives.

LSC System Description The certified GENBAND Release 11.2 LSC is a software-based Voice and Video over Internet Protocol product which includes legacy 2-wire telephones (aka analog 2500 sets), Internet Protocol (IP) telephones, and media processing elements within a local service domain. Additionally, the LSC extends signaling and call control services to allow calls to reach connections outside the local service domain. The LSC software and functions are virtualized and can be distributed logically as well as physically among several high-availability server platforms. This model enables both redundant call management modules and subscriber tables for resiliency.

The certified GENBAND configuration is a secure Unified Capabilities system that provides integrated IP telephony, conferencing, and unified messaging that meets DoD security and service assurance requirements. Although the tested and certified configuration supports voice and video conferencing, only voice conferencing was tested and is certified for use. The testing focused on creating, modifying, and terminating two-party (unicast) or multiparty (multicast) media streams.

Future Plans Contact a GENBAND representative for the latest product development and testing plans.

GENBAND plans to return to JITC to test the GENBAND Enterprise Session Controller (ESC) configuration. The ESC SUT is based on the same software release used for the LSC solution—release 11.2. As part of the ESC testing, the smaller AudioCodes analog line media gateway will be replaced with a carrier class, high-density GENBAND G5 analog media gateway. In addition, the SUT configuration will be augmented with GENBAND’s SPiDR WebRTC media gateway.

GENBAND G5:

A single GENBAND G5 shelf supports up to 768 analog lines and 2,304 subscribers per three-chassis frame. Even large offices of 20,000 lines requiring over 5000 square feet of floor space can be reduced to a few simple frames of space. The line card drives full length (1930 ohm) loop lengths, and the gateway supports carrier-class availability and resiliency including optional support for full Emergency Stand Alone should call control be interrupted. The G5 is also NEBS 3 and OSMINE compliant, meeting the high standards required for carrier physical and operational environments. This gateway platform provides a power profile of about 0.25 watts per subscriber—dramatically lower than most legacy line access equipment deployed by DoD.

The G5 is purposely designed for high-density analog environments where carrier-class reliability is required, making it ideal for DoD base, post, camp and stations. The G5 enables DoD sites to cost-effectively sustain their legacy copper plant and main distribution frames, affording them the time needed to upgrade their base data network to the Assured Service Local Area Network compliant environment to support voice and video over IP.

Video Collaboration (Vidyo Global Video Service):

Vidyo is the key technology provider for DISA’s Global Video Service. GENBAND has a strong partnership with Vidyo for collaboration technology. The technology is already tightly integrated with the GENBAND Application Server, providing a highly secure, advanced collaboration solution. GENBAND will formally test the secure version of Vidyo’s solution with the GENBAND Application Server. Given our close partnership, we expect minimal barriers to completing this effort.

GENBAND SPiDR WebRTC Gateway:
