13.1.2 Paralleled Telephone
Description
By connecting telephones in parallel, you can increase the number of telephones connected to the PBX without
adding additional extension cards.
Both wired and wireless telephones can be connected in parallel. Single line telephones (SLTs), analog
proprietary telephones (APTs), and digital proprietary telephones (DPTs) can be connected to other telephones
or connectors, allowing up to three telephones to be connected to the PBX through just one extension port.
Additionally, portable stations (PSs) can be linked to other telephones wirelessly and used as "paired"
extensions.
The different type of parallel connections are described below.

Connections
Parallel Mode
Allows an SLT to be connected to an APT or DPT
which is connected to a Super Hybrid port of the PBX.
When parallel mode is enabled, the two telephones
function as follows:
•
Both share the extension number of the
telephone connected directly to the PBX (main
telephone).
•
Either telephone can make or answer a call.

EXtra Device Port
(XDP) Mode
Allows an SLT to be connected to a DPT which is
connected to a Super Hybrid port of the PBX.
Unlike parallel mode, XDP mode allows each
telephone to act as an independent extension with its
own extension number. (

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. 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.
