EXtra Device Port (XDP)
Description
EXtra Device Port (XDP) expands the number of telephones available in the system by
allowing an extension jack to contain 2 telephones. A digital proprietary telephone and a single
line telephone (SLT) or console and SLT can be connected to the same jack but have different
extension numbers so that they can act as completely different extensions.
Conditions
• XDP requires previous programming of the individual jack. Enable XDP mode for the
desired jack by System Programming.
