AUX-TRK (Auxiliary Trunk)
The TN763B/C/D and TN417 Auxiliary Trunk circuit packs are used to provide
ports for the following features: Music-On-Hold, loudspeaker paging (voice and
coded chimes), dictation, automated wake-up with AUDICHRON.
Recorder/Announcer, and recorded announcements. TN763C circuit packs
support Mu-law companding. TN417 circuit packs support A-law companding.
TN763D can support either companding mode and defaults to mu-law on
initialization. Companding modes are administered on the country-options
system-parameters screen.
Music-On-Hold is administered via the Feature-Related System Parameters
Form. Loudspeaker paging can be administered via the change paging
loudspeaker or add trunk-group [Customer-Provided Equipment (CPE)]
commands. The change paging loudspeaker command is used for
system-provided paging; the add trunk group command is used for access to
otherwise-provided (CPE) paging. The translation for code chiming is
administered by the change paging code-calling-ids command. Recorded
announcement and dictation are administered by the add trunk-group (CPE)
command. Automatic wake-up is administered by the change
system-parameters hospitality command and uses all four ports on a TN763B
Auxiliary Trunk circuit pack.
Music-On-Hold provides audible feedback to a held, parked, or otherwise
split-away party indicating that the call is still connected. The feedback can be
customer-provided music, a recorded message, or other audible indication. Since
the Music-On-Hold port is always busy, some of its port tests always abort.
The Loudspeaker Paging feature provides voice and/or code calling chime
paging. If multiple paging zones are provided at a customer’s premises, the
Loudspeaker Paging feature gives a user the option of paging to a particular zone
or to every zone. If a zone is active for one page, it cannot be used at the same
time for another.
