MMI Network loopback test
ApplicationsThe LEI is an IPE line card that provides cost-effective connection between
E1-compatible IPE and a CS 1000E, 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 1000E, 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 81 "LEI connection
to IPE" (page 315).
