Applications
The LEI is an IPE line card that provides cost-effective connection between E1-compatible IPE
and a CS 1000E, CS 1000M, and Meridian 1system or off-premise extensions over long
distances.
Some examples of applications where an LEI can be interfaced to an E1 link are:
• E1-compatible VRU equipment
• E1-compatible turret systems
• E1-compatible wireless systems
• Remote analog (500/2500-type) telephones through E1 to channel bank
• Remote Norstar sites behind CS 1000E, CS 1000M, and Meridian 1over E1
The LEI is appropriate for any application where both E1 connectivity and "lineside"
functionality are required. This includes connections to E1-compatible voice response units,
voice messaging and trading turret (used in stock market applications) systems. See
on page 242.

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 can 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 69: LEI in off-premise extension application
page 243. Audible Message Waiting Indicator can be provided as well.
