G6 Universal Gateway About 40,000 TDM switches, serving over 800 million lines globally, are still in operation despite the fact that many are beyond their designed lives. These aging systems pose serious customer, outage, and financial risk to operators, and they are not capable of providing new, advanced IP services to customers nor are they tied to mobile and broadband services. Ribbon Communications’ G6 Universal Gateway resolves the problems associated with aging TDM switches and enables revenue growth by linking TDM customers to mobile, broadband, and SIP-based services. While operators would like to see customers quickly move to their IP-based offerings, the reality is that many customers are slow to migrate to IP for a variety of reasons. This slow migration, coupled with signifi cant risk of TDM switch failure and loss of knowledge base, puts operators’ revenue in serious jeopardy and mandates switch replacement. Part of Ribbon’s Media Gateway product line, the G6 is customdesigned to replace TDM switches. While Ribbon’s G5 Line Access Gateway connects directly to copper pair line interfaces, the G6 provides a full array of trunk interfaces. The G6 supercharges transformation of networks and advances aging TDM switch replacement by connecting to access based trunks such as PBX-centric PRI and T1/E1, as well as lines served by Digital Loop Carrier/Access Nodes and DMS, EWSD, and DCO TDM switch line frames. The G6 also supports intermachine trunks, enabling graceful central offi ce migration, switch by switch. Smart Choice for Access Replacement The G6 provides direct interfaces to Ribbon’s C20 Call Controller or other IP-based call control. When used with the G5 for switch line frame replacement, a TDM switch can be shut down and scrapped, garnering signifi cant operational, floorspace, and other savings. New services can also be delivered to subscribers. TDM access is no longer a dead-end technology, but it is simply another means of accessing the SIP services cloud and mobility, mitigating customer line loss and providing new revenue growth. The Ribbon G6™ Universal Gateway is a carrier-class, multipurpose access and trunking gateway that simultaneously supports multiple VoIP service architectures such as IMS/VoIP/ TDM core. Purpose-built for highly reliable VoIP, the G6 uses the latest generation of advanced platform architecture for high quality VoIP and fax/modem handling, in an environmentallyfriendly low power and small footprint chassis. NEBS Level 3 certifi ed, the G6 is fully redundant, produced in a TL9000 quality system and deployed worldwide in ILEC, PTT, RLEC, CLEC, and cable MSO networks. The G6 supports 240 to 16,128 ports (DS0s) in a single chassis.
