Data Features
Analog Multiline Telephones with
Simultaneous Voice/Data
Use this procedure to dedicate a voice/data pair to provide the Simultaneous
Voice and Data feature to an analog multiline telephone.
The extension number associated with the first (odd-numbered) station jack in
the pair is the telephone's extension number. The extension number for the
second (even-numbered) station jack is dedicated to the Simultaneous Voice
and Data feature.
Calls cannot be placed to the station jack reserved for the
Simultaneous Voice and Data feature.
An extension number cannot be dedicated for both the Voice
Announce to Busy feature and the Simultaneous Voice and Data
feature.
When you select Enter after entering the voice extension number in
the data entry screeen, the system automatically assigns the data
station extension.
Use the Inspect feature to verify the entension pair.
