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 Figure 80 "LEI

connection to IPE" (page 308).
