LEI connection to IPE
For example, the LEI can be used to connect the system to an
E1-compatible Voice Response Unit (VRU). An example of this type of
equipment is Nortel Open IVR system. In this way, the CS 1000E, CS
1000M, and Meridian 1can send a call to the VRU, and, because the LEI
supports analog (500/2500-type) telephone functionality, the VRU is able
to send the call back to the system for further handling.
The LEI can also be used to provide off-premise extensions to remote
locations, up to 500 miles from the system. In this application, analog
telephone functionality is extended over E1 facilities, providing a telephone
at a remote site with access to analog (500/2500-type) telephone line
functionality. See
Figure 81 "LEI in off-premise extension application"
. Audible Message Waiting Indicator can be provided as well.
