ITG engineering guidelines
In a multi-card node, do not have the Leader function and DCHIP function on
the same IP trunk card, unless all voice channels are disabled on that card. A
Leader card must have voice channels provisioned on the IP trunk card to
receive provisioning for the Gatekeeper, but disabling the voice channels
allows the Leader card to handle a significantly higher number of calls/hour.
The IP trunk card providing DCHIP functionality can be any card in the node
including the Backup Leader (Leader 1) and Follower card. As with the
Leader card, disabling the voice channels on the DCHIP card significantly
increases the number of calls/hour that can be processed.
The Leader card supports all Gatekeeper-routed calls, all locally-resolved
calls, or a mixture of both. The Leader card support the same number of
Follower cards for all codecs with payload sizes of 10, 20, and 30
milliseconds, and with VAD on or off.
Table 15, Table 16 on
of the Media Card 32-port trunk card in the role of Leader card and the role
of DCHIP card. This information is equally applicable to single card nodes or
multi-card nodes and small or large IP Trunk networks. Refer to this
information for all Media Card 32-port trunk card installations.
