For example, the Lineside T1 card can be used to connect the system to a T1-compatible VRU.
An example of this type of equipment is Nortel Open IVR system. In this way, the system can
send a call to the VRU. Because the Lineside T1 card supports analog (500/2500-type)
telephones, the VRU can send the call back to the system for further handling.
The Lineside T1 card can also be used to provide off-premise extensions to remote locations
(up to 500 miles from the system). In this application, the analog telephone functionality is
extended over T1 facilities, providing a telephone at a remote site with access to analog
(500/2500-type) telephone lines. See
