There are four possible Media Gateway configurations:
• A pure TDM single Media Gateway with no DSP daughterboards or Media Cards.
• A system with only Voice Gateway Media Cards.
• A system with only DSP daughterboards.
• A system with both DSP daughterboards and Media Cards.
The DB-32, DB-96, and DB-128 are supported in both expansion sites on the MGC card. The
CS 1000E Peripheral Rate Interface (PRI) Media Gateway is required to support an MGC card
populated with greater than 192 DSP ports. The MGC card can support a maximum of 256
DSP ports.
The following table summarizes the supported placement of the DBs in the MGC expansion
sites and the card slots represented by each DB.

Note:
The Extended Media Gateway PRI (MGP) package 418 is required to support MGC cards
populated with two DB-96 or two DB-128.
Card slots are not dedicated. For example, you can configure card 9 and 10 for other card
types when card 0 is configured as DB-128. Similarly, you can configure card 14 or card 15 for
DTR/XTD when card 11,12, and 13 is configured as DB-128.
