P 5.2 Standard Telephone Features
Paralleled Telephone Connection
A proprietary telephone (PT) can be connected in parallel with a standard telephone.
This feature allows the PT user to set whether the paralleled standard telephone will ring
or not, when an incoming call is received.
Conditions
• The default is “Parallel Off (No ring)”.
• When receiving a call:
— If standard telephone is set to ring, then both the PT and the standard telephone will
ring except when the PT is in “Handsfree Answerback” mode or Voice-Calling mode
with the “Alternate Calling — Ring/Voice” feature.
— If standard telephone is not set to ring, then only the PT rings. However, the
standard telephone can answer the call.
• If you go off-hook while your paralleled telephone is in use, the call will switch over to
your telephone, and vice versa.
• The “XDP*” feature is available.
