Paralleled 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.
To enable / disable SLT ringing
PT
Lift the handset or press
SP-PHONE/MONITOR.
Conditions
• The default is "Parallel Off (No ring)."
• The PT can be used to perform normal operations whether or not the SLT is set to ring.
• When receiving a call:
— If SLT ringing is enabled, then both the PT and the SLT will ring except when the
PT is in "Hands-free 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.
• When the SLT is in use, the display and the indicators of the PT will work in the same
way as if the PT is in use.
• In the DPT + SLT 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 + SLT combination, if one telephone goes off-hook while the other
telephone is on a call, a 3-party call is established. If one user goes on-hook, the other
user continues the call.
• The "XDP*" feature is available. Refer to the Installation Manual.
