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 card in the Media Gateway:
• The Server card cannot be placed in slot 0 of any Media Gateway. Slot 0
is reserved for the Gateway Controller.
• To allow for ease of cabling, theServer card may be placed in slots 1
through 4 of the chassis, with the exception of the Option 11C Mini. The
Option 11C Mini cannot have a Server card installed in slot 4 as this slot
was originally allocated for the 48 port DLC only. The Signaling Server
may be placed in slots 1 through 4 (see Figure 9 on
chassis if necessary.
• If utilizing the Campus Redundancy High Availability (HA) Call Server
option, place the two CP PM call servers in separate chassis's to allow
for increased survivability. HA is not supported on a Co-resident Call
Server and Signaling Server system.
