3.3.38 TMCAS-2 (for selected countries only)
Introduction
The TMCAS-2 card (Trunk Module Channel Associated Signaling) can be used in HiPath 3800
for V5.0 SMR-10 and later to support country-specific CAS protocols.
The card features two E1-CAS interfaces, which together support up to 60 B channels.
Both coaxial trunks (75 ohms) and symmetrical trunks (120 ohms) can be connected to the 15-
pin sub-D jacks on the card.
TMCAS-2 functions as a converter, which converts the Euro-ISDN protocol on an S
2M
link to
the Channel Associated Signaling (CAS) protocol. In contrast to the predecessor PBXXX card,
TMCAS-2 communicates directly with the central control in the system. All signaling and data
traffic goes through TMCAS-2. Unlike PBXXX, a connection with an S
2M
card is therefore not
required.
Up to three TMCAS-2 cards can be used in a HiPath 3800.
