Introduction
The following cards - one per system - can be used for V5.0 SMR -10 and later to support coun-
try-specific CAS (Channel Associated Signaling) protocols:
TCAS-2 (S30810-Q2945-X) in HiPath 3550
●
TCASR-2 (S30810-K2945-X) in HiPath 3500
●
Please note that the cards listed can only be used in slots 7 and 9.
Each of the cards features two E1-CAS interfaces, which together support up to 60 B channels.
Since HiPath 3550 and HiPath 3500 each support a maximum of 30 B channels, a total of up
to 30 B channels can be used per card.
Direct connection to the MINI BNC connectors on each card is only possible for coaxial trunks
(75 ohms). An external
trunks (120 ohms).
TCAS-2 and TCASR-2 function as converters, which convert the Euro-ISDN protocol on an
S link to the Channel Associated Signaling protocol CAS. In contrast to the predecessor TM-
2M
CAS card, TCAS-2 and TCASR-2 communicate directly with the central control in the system.
All signaling and data traffic goes through TCAS-2 and TCASR-2. Unlike TMCAS, connection
to an S card is therefore not required.
