Paralleled Telephone
Description
Any PT can be connected in parallel with an SLT.
The following two combinations of telephones are available:
a)
APT + SLT (an Analog Proprietary Telephone and a Single Line Telephone / a single
extension port)
b)
DPT + SLT (a Digital Proprietary Telephone and a Single Line Telephone / a single
extension port)
When a parallel connection is made, an extension user can make and answer a call using either
one of two telephones.
Conditions
• Hardware Requirements
DHLC card (KX-TD50170) or HLC card (KX-T96170) is required to utilize this feature.
• To enable Paralleled Telephone mode, set "Parallel / XDP" to "Parallel" in the Extension
Port Assignment screen <Section "1.4 Extension Port Assignment" in the Programming
Guide>.
• The corresponding PT user can activate or deactivate the paralleled SLT ringing by dialing
the feature number for "Parallel telephone mode."
• Paralleled Telephones (APT+SLT / DPT+SLT) share the same extension number.
• Extra Device Port (XDP)
If EXtra Device Port feature (DPT+SLT) is activated, each telephone has its own unique
extension number and acts as completely different extensions.
• The PT can be used to perform normal operations whether or not the SLT is enabled.
• 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.
• When receiving a call;
The SLT is activated; Both the PT and the SLT will ring except when the PT is in Hands-
free Answerback mode or Voice Alerting mode.
The SLT is deactivated; PT rings but the SLT does not ring.
• When the SLT is in operation, the display and LED indicator on the paired PT will work in
the same way as if the PT is in operation.
• If APT + SLT are used, the extension user cannot originate a call from the SLT if the APT
is:
— playing BGM
— in programming mode
— receiving a paging announcement over the built-in speaker
