Chapter 2 Solution Components

Media Gateways

Note Within the Cisco Multiservice Packet Network Solution, the VISM hardware supports either VISM

Software Release 2.1 (MGX-VISM-SW2100) or Release 3.0 (MGX-VISM-SW3000), and the VISM-PR

hardware supports only VISM Software Release 3.0 (MGX-VISM-SW3000).

Table 2-2 lists the codecs supported by each VISM module within the Cisco Multiservice Packet

Network Solution.

Configurations

Platform components are dependent on the size of the application. For small applications, the MGX 8230

Edge Concentrator is recommended. See Table 2-3 for a configuration that supports up to 32 E1 lines

using one SRM/E card. See Table 2-4 for a configuration that supports up to 64 E1 lines using two

SRM/E cards, one on each shelf.
