IVC Card Features and Support

Chapter 2

IVC Cards and Modules

The hardware that supports Integrated Voice Services (IVS) and provides interactive

voice response (IVR) functions is either an Integrated Voice Controller (IVC) card or

module. Each IVC card or module supports up to 72 ports for a PointSpan switch. Each

port (also called an IVC device) plays IVS phrases and collects dual-tone multi-frequency

(DTMF) digits. An IVS phrase can contain speech, tones, music, or other forms of audio.

A PointSpan switch supports over 65,000 IVS phrases. With more IVC cards or modules,

a switch increases the number of IVC devices that are available.

Each IVC card or module supports up to 89 minutes of pre-recorded audio. The hard

drive of a PointSpan system can store up to 190 minutes of pre-recorded audio. You can

distribute the audio on the hard drive to many different IVC cards, as needed to support

IVS groups, IVS phrase groups, hardware partitions, and system capacity.

Each IVC card resides in one of the 16 universal slots in a PointSpan Interface Shelf,

Interface Module, or Fiber Extended Node (FXN).

Slot 16 of an FXN Fiber Exchange Link (FXL) shelf, however, cannot support an IVC

card, because that slot does not support 72 ports.

Connectors with latching levers on the front edge seat the card securely in corresponding

backplane connectors. A 3-amp fuse (F9) protects the card's +5 V dc circuit.

The rear edge of the card provides the following interface connections:

• A control and interface link connector (P1)

• An 8-pin power connector (P2)

• Two 10BaseT data connectors (P3 and P4)
