Applications
The lineside T1 interface is an IPE line card that provides cost-effective
connection between T1-compatible IPE and a system or off-premise
extensions over long distances.
Some examples of applications where a lineside T1 card can be interfaced to
a T1 link are:
• T1 compatible Voice Response Unit (VRU) equipment
• T1 compatible turret systems
• T1 compatible wireless systems
• Remote analog (500/2500-type) telephones through T1 to a channel bank
• Remote Norstar sites behind CS 1000S, CS 1000M, and Meridian 1 over
T1
The lineside T1 card is appropriate for any application where both T1
connectivity and “lineside” functionality is required. This includes
connections to T1-compatible voice response units, voice messaging and
trading turret (used in stock market applications) systems. See Figure 34.
