Overview" on page
The Server card interfaces with the Media Gateway through the Gateway
Controller using the ELAN interface, and therefore does not require
backplane connectivity (other than power and slot ID). The following rules
apply to the preferential placement of the Server cards in the Media Gateway:
• The Server cards cannot be placed in slot 0 of any Media Gateway. Slot
0 is reserved for the Gateway Controller.
Note: The CP MG card functions as the Server and the Gateway
Controller while occupying slot 0 in a Media Gateway.
• To allow for ease of cabling, the Server card can be placed in slots 1
through 4 of the chassis, with the exception of the Option 11C Mini
chassis. The Option 11C Mini chassis cannot have a Server card installed
in slot 4 as this slot was originally allocated for the 48 port DLC only.
• If utilizing the Campus Redundancy High Availability (HA) Call Server
option, place the two CP PM call servers in separate chassis' to allow for
increased survivability. HA is not supported on a Co-resident Call Server
and Signaling Server system.
Figure 6 shows an existing Option 11C or Avaya Communication Server
1000M chassis call server with the SSC card. After the upgrade, an SA Media
Gateway chassis system resembles Figure 7 on
Controller in slot 0, and Server cards in the main chassis. The additional
Media Gateways contain Gateway Controller cards only for an SA
configuration.
