E1 CAS Access
●
A TME1 module with E1 CAS access consists of a Digital Interface Unit (DIU) used for
connecting the HiPath 1150/1190/1190R to the PSTN via a E1 trunk. The E1 trunk can carry
30 digital voice channels. However, the HiPath 1150 systems use up to 20 channels, while the
HiPath 1190 systems use up to 30 channels with the TME1 module allocated to slot 1 and up
to 15 channels when it is allocated to slot 11.
Functions

●
Provides Caller ID (CLIP) and Direct Dialing to Extensions (DID) to help reduce
