mG9K Media Gateway

GENBAND Difference

Widely deployed since 2002, GENBAND’s Media Gateway 9K is a powerful solution designed to efficiently connect disparate networks, enable multimedia communications over multiple transport protocols, and manage calls, signaling and other variables.

The GENBAND mG9K enables subscriber lines to connect directly to an ATM/IP packet backbone. Service providers can deploy the mG9K with the GENBAND C20 to deliver switched services such as POTS and non-switched services such as ADSL. This carrier-grade gateway supports a long list of narrowband and broadband services simultaneously, including all DMS-100 line services, without the need for an overlay network thereby enabling central office consolidation and modernization.

Overview

Carrier-Grade Reliability: This media gateway delivers robust performance, full redundancy for all components, and incorporates advanced isolation features to help prevent any fault from disrupting other services.

ATM Self-Healing Circuits: Self-healing ATM switched virtual circuits are used to transport voice and data traffic. If an ATM network path is lost, the mG9K automatically reestablishes the connection through an alternate backbone pathway.

Broad Service Capabilities: The feature-rich mG9K supports a long list of broadband and narrowband services simultaneously, including key line services. As an integrated access platform, this gateway integrates seamlessly into existing networks, supporting a wide range of subscriber-side interfaces and revenue-generating services.

The mG9K supports narrowband POTS, residential and Custom Local Area Signaling Services (CLASS). It also supports traditional line types such as Centrex, Coin, ground start and Meridian Business Set. Service providers can rely on this media gateway to deliver structured and unstructured DS-1, fractional DS-1, and DS-1 grooming for Circuit Emulation Services, and for private leased lines over ATM networks. The mG9K also supports POTS + Digital Subscriber Line (xDSL) options, including ADSL (full-rate Discrete Multi-Tone) with no need for splitters or DSLAM equipment. The mG9K also integrates smoothly with BASG 7500/7600 Series Mini-DSLAM Series to deliver exceptional DSL performance.

Scalable and Flexible Architecture: This highly flexible platform scales economically to support over 7,900 POTS lines across multiple shelves, all off of a single network interface. The integrated POTS + ADSL service can support up to 112 ADSL + POTS lines from a single shelf. The mG9K’s maximum frame capacity with the BASG 7500/7600 Series configuration is 1440 POTS, 224 DSL w/o 8x8, or 1128 POTS, 328 DSL w/8x8. This GENBAND media gateway is hardened for deployment in outside plant cabinets.

Integrated POTS and ADSL Services: The mG9K features a combined POTS and ADSL ServiceModule capable of supporting a number of subscribers and providing both POTS and full-rate ADSL services over a single twisted pair loop. An internal frequency splitter on board this ServiceModule separates the POTS and ADSL services for independent processing and packetization.

Performance, Cost and Market Advantages: The mG9K has the ability to host existing DMS line and trunk peripherals and industry-standard remotes, ensuring a smooth upgrade of DMS and other switching centers to full packet capability. Support for hosted peripherals includes mG9K intraswitching capability, dynamic packet trunking capability, emergency standalone and echo cancellation.

Ease of Installed Location: When deployed in a Local VoIP configuration, the mG9K may be located up to 950 air miles (1,425 fiber miles) from a C20. With this deployment range, a single centrally located C20 can support two mG9Ks located almost 2,000 air miles (almost 3,000 fiber miles) apart. This range allows carriers to enter into new markets with a minimal investment when compared to the cost of a traditional TDM network.

Extend Class 5 Reachability: Supports loop resistances up to 1900 ohms, thus subscriber loops can reach up to 18,000 feet (5,486 meters) in length. In comparison, typical DLCs support a maximum loop resistance of 1350 ohms, which limits loop length to 12,000 feet (3,658 meters) or less.

Emergency Services: This GENBAND media gateway also provides Emergency Stand Alone (ESA) capability to support basic intraswitched POTS service and E911 translations in ESA mode for native lines, DMS peripheral lines and standard DLC lines.

DMS smooth migration to VoIP: Re-use DMS remote peripherals while offering all existing DMS functionality including regulatory services.
