Introduction
The TMS2 board (trunk module S2M) provides 30 B-channels (ISDN voice channels) for Hicom 150 E OfficePro. These channels can be used fro the following:
![]() |
S2m trunk connections (via NT) |
![]() |
S2M networking via S2M lines |
You can use the Euro-ISDN CAS gateway (ECG) to support country-specific CAS protocols. The ECG is a protocol converter that converts the Euro-ISDN subset to channel-assiciated signaling (CAS). Refer to the installation instructions that come with each ECG for information on connecting the unit and supplying it with power.
