Any proprietary telephone can be connected in parallel with a
standard telephone. The following two combinations of telephones
are available:
(1)APT + Standard Telephone (an analog proprietary
telephone and a standard telephone/device)
(2)DPT + Standard Telephone (a digital proprietary telephone
and a standard telephone/device)
When a parallel connection is made, an extension user can make
and answer a call using either telephone.
• The proprietary telephone (PT) can be used to perform normal
operations whether or not the standard telephone is enabled.
• In the DPT + standard 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 + standard 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 standard telephone is activated; both the PT and the standard
telephone will ring except when the PT is in Handsfree Answerback
mode or Voice Alerting mode.
The standard telephone is deactivated; the PT rings but the standard
telephone does not ring. However, the standard telephone can answer
the phone.
• When the standard 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 + standard telephone are used, the extension user cannot
originate a call from the standard 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 + standard telephone
can act as completely different extensions.
• The Call Waiting tone can be heard only by a PT.
• If a standard telephone with the Caller ID feature is connected in
parallel, the Caller ID feature will not function.
