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) .
