Media Gateway/Media Gateway Expansion card slot assignment 1025
Conferencing
Thirty-two conference channels are provided by the NTDK20 SSC card’s
conference devices. Conference capability can be increased by mounting
expansion daughterboards on the NTDK20 SSC card. Each dual IP
daughterboard increases the total number of conference channels by 32.
The maximum number of conference ports is 96.
Each conference device provides 32 ports of conferencing capabilities (one
conference participant for each port). A conference call can involve three
to six participants. For example, there could be six 5-party conferences on
each device, or four 6-party conferences plus two 3-party conferences. It is
not possible to conference between conference devices.
10BaseT port
The Call Server provides one 10BaseT connection to a Local Area Network
(LAN) to interface with Management software applications such as OTM
and CallPilot. The Media Gateway SSC 10BaseT port, Port 1, is disabled by
default. To use the 10BaseT port, the port must be assigned a unique IP
address and the port must be enabled from the Call Server.
The Media Gateway 10BaseT port can run in Normal mode or Survival
mode. In normal mode, the Media Gateway does not provide access to
maintenance or alarm management.
External connections to the 10BaseT port are provided by a 15-pin
connector located on the backplanes of the Call Server and Media
Gateways.
Media Gateway/Media Gateway Expansion card slot assignment
The Media Gateway and Media Gateway Expansion contain physical card
slots, numbered 1 to 10. See
Figure 289 "Media Gateway slots" (page
1026) and Figure 290 "Media Gateway Expansion slots" (page 1027) .
When configuring the system, the physical card slot numbers must be
transposed to "logical" card slot numbers. For example, to configure a card
physically located in Slot 2 of the first Media Gateway, use logical Slot 12. To
configure a card physically located in Slot 2 of the second Media Gateway,
use logical Slot 22. See
Table 426 "Media Gateway and Media Gateway
Expansion slot assignments" (page 1026) .
