Extension Jack Pairs for Analog Telephones

Use these instructions only if the system has analog multiline telephones.
Otherwise, skip to the next section, "Jacks for MLX Telephones."
MLX telephones can use the Voice Announce to Busy feature or simultaneous
voice and data without requiring a second extension jack.
Analog multiline telephones require an additional extension jack to use Voice
Announce to Busy or voice and data. The jacks must be an odd-numbered
analog extension jack and the next higher (even-numbered) analog extension
jack. The system assigns individual extension numbers to each of the jacks. The
extension number associated with the first (odd-numbered) extension jack in the
pair is the telephone's extension number. Calls cannot be placed to the
extension number associated with the even-numbered extension jack. (For
information about renumbering jacks, see "System Renumbering" later in this
chapter.)
You can assign Voice Announce to Busy or voice and data to any of the analog
multiline telephones in the system, but you cannot assign both to the same
telephone.
