The four media module slots can be populated with any combination of media module types:
T1/E1 with integrated CSU/DSU (MM710)
8-port analog line/trunk (MM711)
8-port DCP line (MM712)
8-port BRI trunk (MM720)
VoIP Engine (MM760)
Internal Communications Controller (ICC-only 1 per gateway; must be in the first slot)
The Cascade module comes from the Converged Infrastructure LAN Switches product line, and
provides the Octaplane interface:
One full-duplex 4-Gbps Ethernet port (8 Gbps bandwidth) for high-speed interconnection
of up to 10 media gateways and P330 data switches in a stack arrangement
Expansion module interface allows the use of expansion modules in the gateway. These
expansion modules also allow WAN access routing.
The G700 motherboard hardware design involves three major blocks:
A DSP engine and associated packet processor complex. This complex performs IP/UDP/
RTP processing, echo cancellation, G.711 A/µ, G.729 (with or without silence
suppression), fax relay, silence suppression, jitter buffer management, packet loss
concealment, and so on.
A Gateway Processor complex. This complex is the master controller of the Gateway, and
controls all resources inside the Gateway under the direction of the Gateway Controller.
Examples of the functions implemented here include the Media Module Manager, Tone/
Clock, PKTINT, Announcements (record/playback), and H.248 signaling to the Gateway
Controller.
