Paralleled Telephone - Panasonic KX-TD816 Features Manual

Paralleled Telephone

Description
Any proprietary telephone can be connected in parallel with a single line telephone. The
following two combinations of telephones are available:
a)
APT + Single Line Telephone (an analog proprietary telephone and a single line
telephone/device)
b) DPT + Single Line Telephone (a digital proprietary telephone and a single line
telephone/device)
When a parallel connection is made, an extension user can make and answer a call using either
telephone.
Conditions
• The proprietary telephone (PT) can be used to perform normal operations whether or not
the single line telephone is enabled.
• In the DPT + single line telephone combination, if one telephone goes off-hook while the
other telephone is on a call, the call is switched to the former.
• In the APT + single line telephone combination, if one telephone goes off-hook while the
other telephone is on a call, a three-party call is established. If one user goes on-hook, the
other user continues the call.
• When receiving a call;
The single line telephone is activated; both the PT and the single line telephone will ring
except when the PT is in Handsfree Answerback mode or Voice Alerting mode.
The single line telephone is deactivated; the PT rings but the single line telephone does not
ring. However, the single line telephone can answer the phone.
• When the single line telephone is in operation, the display and LED (Light Emitting Diode)
indicator on the paired PT will work in the same way as if the PT is in operation.
• If APT + single line telephone are used, the extension user cannot originate a call from the
single line telephone if the APT is:
— playing Background Music (BGM)
— in programming mode
— receiving a paging announcement over the built-in speaker.
• If eXtra Device Port feature is available, a DPT + single line telephone can act as
completely different extensions.
• The Call Waiting tone can be heard only by a PT.
• If a single line telephone with the Caller ID feature is connected in parallel, the Caller ID
feature will not function.
