Parallelled Telephone Connection
A proprietary telephone (PT) can be connected in parallel with a single line telephone
(SLT). This feature allows you to enable or disable SLT ringing. When a parallel
connection is made, either telephone can be used. The SLT can be disabled by the PT
user.
Conditions
• Default is “Parallel Off.”
• When receiving a call:
— If SLT ringing is enabled, then both the PT and the SLT ring except when the PT
is in “Handsfree Answerback” mode or Voice-Calling mode with the “Alternate
Calling — Ring/Voice” feature.
— If SLT ringing is disabled, then the PT rings but the SLT does not. However the
SLT can answer the call.
• If you go off-hook while your parallelled telephone is in use, the call will switch over
to your telephone, and vice versa.
• “XDP*” feature is available. Refer to the Installation Manual.
