in the system by allowing an extension jack to contain two
telephones. A digital proprietary telephone (DPT) and a single line
telephone (SLT) can be connected to the same jack but have
different extension numbers so that they can act as completely
different extensions.
• XDP requires previous programming of the individual jack. Enable
XDP mode for the desired jack by system programming. Immediately
after changing the assignment, changed setting may not work for a
maximum of eight seconds.
• If an SLT is connected to an XDP-enabled jack, neither telephones
work.
• If XDP is disabled for the jack, DPT and SLT may be used as Paralleled
Telephones.

The numbers used for the access codes of system features and the
number used for extension numbers are not fixed. They can be set
as required provided there are not any conflicts. Feature numbers
can be from one to three digits, utilizing numbers "0 through 9" as
well as " " and "#." Extension numbers can be two to four digits
in length. Any number can be set as the leading first or second
digit. If one digit is assigned as the leading digit, some extensions
have 2-digit numbers and some have 3-digit numbers. If two digits
are assigned as the leading digits, some have 3-digit numbers and
some have 4-digit numbers.
