Appendix B: Administering VRUs/IVRs as
station ports
When Voice Response Units (VRUs) or Interactive Voice Response Units (IVRs) are used
in a contact center as station ports in a hunt group or in an ACD split/skill, either as a non-
vector controlled split or accessed via the
converse
,
queue-to
, or
route-to
command, the station ports must be administered on the station form with the “type”
required by the VRU/IVR ports. The types for VRU/IVR ports supported by Avaya switches
are:

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

ds1fd
ds1fd provides an EIA/TIA 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 msecs.
This type is used for Conversant
Line Side T1/E1 ports 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 ds1fd,
except C&D tone support is
provided. This type of
administration is not used for
Conversant.
