Features
EXtra Device Allows an SLT to be connected to a DPT which is
Port (XDP) connected to a Super Hybrid port of the PBX.
Mode
Unlike parallel mode, XDP mode allows each telephone to
act as an independent extension with its own extension
number. (→ 2.1.1 Extension Port Configuration)
Digital XDP Allows a DPT to be connected to another DPT which is
connected to a DPT port or a Super Hybrid port of the PBX.
Similar to XDP mode, each DPT acts as an independent
extension with its own extension number.
In a Digital XDP connection, the DPT connected to the PBX
is called the "master DPT", and the DPT connected to the
other DPT is the "slave".
Additionally, an SLT can be connected to the master DPT
in either parallel or XDP mode.
Wireless XDP For information on this type of parallel connection, refer to
Parallel Mode the Wireless XDP Parallel mode feature. (→ 1.22.3
Wireless XDP Parallel Mode)
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.
