Description
Multiple telephones can be connected to the sa me port. This is useful to increase the number
of telephones without additional extension cards. The combi nations and features of the
parallelled telephones are described below.
Features Descriptions Connections
Parall el
Mode Parallel connection allows the connection of an
SLT to an APT or a DPT that is connected to a
Super Hybrid port.
When parallel mode is enabled, the two
telephones function as follows:
• Both share one extension number
(main telephone’s extension number).
• Either telephone can mak e or an swer
a call.
• If one goes off-hook while the other is
on a call, the call is switched to the
former.
EXtra Device
Port (XDP)
Mode
XDP mode can be used when the main
telephone in a parallel connection is a DPT
connected to a Super Hybrid port.
Unlike parallel mode, each telephone can act
as a completely different extension with its own
extension number. ( 2.1.1 Extension Port
Configuration)
Digital XDP The Digital XDP allows two DPTs to be
connected together when one of them is
connected to the following port:
• a DPT or Super Hybrid port (with th e
KX-TDA30/KX-TDA100/KX-TDA200)
• a Super Hybrid port (with the KX-
TDA15)
The DPT that is connected directly to the PBX
is called the "master DPT", and the DPT
connected to the master is the "slave DPT".
Like XDP mode, each telephone can act as a
completely different extension with its own
extension number.
In addition to a slave DPT, the master DPT
(connected to a Super Hybrid port) ca n have an
SLT in parallel or XDP mode.
