LEI connection to IPE
Forexample, the LEI can be used to connect the system to an E1-compatible
VoiceResponse Unit (VRU). An example of this type of equipment is Nortel
Open IVR system. In this way, the CS 1000E, CS 1000M, and Meridian
1 can 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 82 "LEI in off-premise extension application" (page
315). Audible Message Waiting Indicator can be provided as well.

Similarly,use the LEI to provide a connection between the system and a
remote Norstar system. See Figure 83 "LEI connection to Norstar system"
(page 316). In this case, channel banks are not required if the Norstar
system is equipped with an E1 interface.
