Applications

The LEI is an IPE line card that provides cost-effective connection between E1-compatible IPE and a CS 1000S, CS 1000M, and Meridian 1 system 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 1000S, CS 1000M, and Meridian 1 over 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 Figure 59.
