88 Avaya Application Solutions IP Telephony Deployment Guide
Since H.323 allows any of several different codecs to be used for encoding an audio stream on
the IP network, the Media Processor board is able to use any of the following codecs:
● G.711
● G.723.1
● G.726 (on the TN2602AP circuit pack only)
● G.729 (A, B)
In the same way that a Media Processor board interfaces with IP Telephony endpoints, it can
connect to another Media Processor board to interconnect two or more Avaya switches in an IP
network over an IP trunk.
Media Gateways
The MCC1, SCC1, and G650 Media Gateways are supported in a fiber-PNC configuration.
An S8700-series fiber-PNC configuration can have a mixture of MCC1 and SCC1 cabinets.
However, the type of cabinet cannot be split within a Port Network.
Multi-Carrier Cabinet (MCC1) Media Gateway - The MCC1 Media Gateway can contain up to
five of the following carriers:
● A Port Carrier that contains one or more of the following:
- Port circuit packs
- VOIP conversion resources
- Service circuit packs
- Tone clocks
- Expansion Interface (EI) circuit packs
● A Switch Node Carrier that contains Switch Node Interface circuit packs that compose the
Center Stage Switch (CSS).
● An Expansion Control Carrier that contains service slots and port slots.
The MCC1 Media Gateways can support a maximum of 98 trunk or line port circuit packs.
