DESIGN
The V-9972 allows using a spare E&M port in a
5ESS central office to access a paging system or a
Valcom Page Control Unit. The unit is designed with
the idea that the central office will be using the meet-
me function to allow the paged party to answer the
page.
The 5ESS central office seizes the unit with the E-
Lead and the unit starts an adjustable 4 to 64 second
page length timer and connects the calling party to the
page control unit/paging system. The calling party
makes their page and the page length timer
disconnects the page control/paging system and gives
the calling party optional background music. If the
paged party answers the page using the meet-me
function of the 5ESS or the calling party hangs up,
the E-Lead releases and resets the unit. If the paged
party doesn't answer, then a second adjustable 30 to
180 second timer that started when the music started
will release the unit at the programmed time.
