Other Gatekeepers accept the FACILITY redirect and registration of multiple
IP trunk cards in a single RRQ; that is, the Followers are registered with, and
at the same time as, the Leader.
IP Trunk 3.01 (and later) interworks with the CS 1000S/CS 1000M systems
and IP Peer Networking. As CS 1000S/CS 1000M and IP Peer Networking
use MCDN only, the only applicable protocol is MCDN. IP Trunk 3.01 (and
later) uses the "interoperability format" of the non-standard data with IP Peer
Networking and all other gateways accessible through CS 1000S/CS 1000M.
When IP Trunk 3.01 (and later) inter-operates with itself, with ITG Trunk
2.x.25, or with BCM 2.5 FP1, the IP Peer Networking CS 1000S/CS 1000M
Gatekeeper is not required. The existing ITG Trunk 2.1 node-based dialing
plan is converted automatically to IP Trunk 3.01 (and later) by OTM 2.1 (and
later).
There are no direct media paths between the Meridian 1 telephones and the
CS 1000S/CS 1000M telephones. There are direct paths between the IP
Trunk 3.01 (and later) IP trunk cards and the CS 1000S/CS 1000M
telephones.
When the IP Trunk card is in a CS 1000 system, it can take advantage of the
Dynamic Loss Plan developed for the IP Peer product. This allows the system
core to inform the IP Trunk card of the correct pad levels to be used. As with
IP Peer, it also allows the creation of a custom table when the environment
requires one.
When using Dynamic Loss Plan, the node must be provisioned to have a
default loss plan pad of 0 in both the transmit and receive directions. This
allows a 0 transmit and receive level when the IP Trunk has a tandem to
another trunk device, improving voice quality.
