in the system by allowing an extension jack to contain two
telephones. A digital proprietary telephone (DPT) and a standard
telephone 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
l
XDP mode for the desired jack by System Programming. Immediately
after changing the assignment, the changed setting may not work for a
maximum of eight seconds.
If an analog proprietary telephone (APT) and a standard telephone are
l
connected to an XDP-enabled jack, neither telephones will work.
If XDP is disabled for the jack, DPT and a standard telephone may be
l
used as Paralleled Telephones. APT and a standard telephone also can
be used as Paralleled Telephones.
