Peripheral Boards
3.3.32 TMCAS (for selected countries only)
Introduction
For V1.0 and later, TMCAS (Trunk Module Channel Associated Signaling) boards can be used
in HiPath 3750, HiPath 3700, and HiPath 3550 to support the country-specific CAS protocol.
The board converts the Euro-ISDN protocol on an S
2M
link into the Channel Associated Sig-
naling (CAS) protocol. The board functions only in connection with a TMS2 (HiPath 3750, Hi-
Path 3700) or TS2 (HiPath 3550). There is no direct connection between the TMCAS board and
the system’s central control unit. The TMS2/TS2 handles all signaling and data traffic.
