Conditions
[APT + SLT]
• If one telephone goes off-hook while the other is on a call, a three-party call is established. If one user
goes on-hook, the other user continues the call.
• An extension user cannot originate a call from the SLT if the APT is:
– playing background music (BGM)
– receiving a paging announcement over the built-in speaker.
• The SLT will always ring for incoming calls (if its ringer is turned on). It cannot be programmed to not
ring.
Descriptions
Allows a DPT to be connected to another DPT which
is connected to a DPT port or a Super Hybrid port of
the PBX. The DPT that is connected directly to the
PBX is called the "master DPT", and the DPT
connected to the master DPT is called the "slave
DPT".
Similar to XDP mode, each DPT acts as a
independent extension with its own extension
number.
If a master DPT is connected to the PBX by a Super
Hybrid port (not a DPT port), a third telephone (SLT)
can also be in parallel or XDP mode with the master
DPT.
Digital XDP connection allows the number of DPTs
that the PBX supports to increase.
For information on this type of parallel connection,
refer to the Wireless XDP Parallel mode feature. (→
1.20.4 Wireless XDP Parallel Mode).
