IVR or VRU ports

Last Updated : May 24, 2013 |

When using Interactive Voice Response (IVRs) systems or Voice Response Units (VRUs) as station ports in a hunt group, you must administer the station ports on the Station screen with the type required by the IVR or VRU ports.

The following table lists the types for VRU or IVR ports supported by Communication Manager.

VRU or IVR port type

Forward disconnect

C&D tones support

Station type

Description

Analog T&R

No

2500

Standard station set interface. Uses an analog line circuit pack, such as TN2135.

Analog T&R

Yes

VRU

Provides standard station set interface with C&D tones support using the DTMF Feedback Signals feature.

Lineside DS1/DS0 or lineside T1/E1

Note:

DS1 circuit packs (TN767E or later or TN464F or later) must be equipped.

No

No

ds1–ops

OPS is a DS1 type that provides a TIA/EIA off-premise station type DS1 interface used where the device does not require or support forward disconnect.

Lineside DS1/DS0 or lineside T1/E1

Yes

No

ds1–fd

ds1–fd provides a TIA/EIA Foreign eXchange (FX) type DS1 interface. The forward disconnect signal is a toggle of the A bit from 0 to 1 and then back to 0 after 600 milliseconds. This type is used for line side T1/E1 ports on the IVR system when used as an analog-like VRU device and is the recommended method for interfacing.

Lineside DS1/DS0 or lineside T1/E1

Yes

Yes

VRUFD

VRUFD is the same as ds1–fd but with C&D tone support. An IVR system does not use this type of administration.

Lineside DS1/DS0 or lineside T1/E1

Yes

No

ds1–sa

ds1–sa provides a TIA/EIA special-access type DS1 interface. The forward disconnect signal is a toggle of the A bit from 1 to 0 and then back to 1 after 600 milliseconds.

Lineside DS1/DS0 or lineside T1/E1

Yes

Yes

VRUSA

VRUSA is the same as ds–1sa but with C&D tone support.
