Circuit Card
Description and Installation
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 is able
to 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 Figure 38 on
. An audible message-waiting indicator can
be provided as well.
