Overview
22 Hardware Description and Reference for Avaya Communication Manager
Avaya media gateways have the following benefits:
● Interoperable with standards-based data networks
● Stackable, modular, and configurable component solutions
● Can provide redundant equipment and capabilities
● Can provide distributed networking
● Compatible with cabinets in traditional Avaya systems
Categories of media gateways
There are two primary categories of media gateways:
● Those that use media modules to connect to endpoints and trunks. These media gateways
are usually used at branch and smaller locations and include:
- G700 Media Gateway
- G350 Media Gateway
- G250 Media Gateway
- G150 Media Gateway
● Those that use circuit packs to connect to endpoints and trunks. These media gateways
are usually used at central and large locations, and include:
- G650 Media Gateway
- G600 Media Gateway (no longer sold, but still supported)
- CMC1 Media Gateway
- SCC1 Media Gateway (no longer sold, but still supported)
- MCC1 Media Gateway (no longer sold, but still supported)
Carrier types
Most media gateways that use circuit packs may also be further classified by carrier type. A
carrier holds a row of circuit packs and connects them to power, the TDM bus, and the packet
bus. There are five types:
● A control carrier that contains the processor circuit pack(s). The DEFINITY Server CSI
uses one CMC1 Media Gateway of this carrier type, and the DEFINITY Server SI uses one
SCC1 Media Gateway of this carrier type because control carriers are required to house
the DEFINITY processor circuit packs.
