without additional extension cards. The combinations and features of the parallelled telephones are

Descriptions
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 make or answer a call.
• Both telephones cannot participate in a call
simultaneously. If one telephone is on a call
when the other telephone goes off-hook, the
current call will be switched to that telephone.
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)
The Digital XDP allows the connection of a DPT, to a
DPT that is connected to a DPT or Super Hybrid
port. 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) can have an SLT
in parallel or XDP mode.
