OFFICE DATA PROGRAMMING

2.2 Required Hardware (Point-to-Multipoint Connection)

This feature (allowing IPTRK circuit cards for both speech and CCIS signal channels) is available by using
the following hardware. Once this feature is set, each IPTRK circuit card can make a Point-to-Multipoint
connection with IPTRK circuit cards of multiple nodes.

Note:

One IPTRK circuit card assigned as CCH by the ACSC command is assumed as the D-channel controlling
card, used as the speech circuit card as well. The IPTRK circuit card can control the B-channel of the same
card, and a maximum of seven other IPTRK circuit cards.
