2.2 Required Hardware (Point-to-Multipoint Connection)
This feature (allowing IPTRK circuit card s for both speech and CCIS signal channe ls) 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 circu it card ca n control the B-channel of the same
card, and a maximum of seven other IPTRK circuit cards.
