System Description
Message Register
The message register provides the ability to keep track of the number of completed
external calls or call units for each extension. This feature applies to consoles, industry
standard telephones, and SUERSE7telephones. The extension or console which
answers an incoming trunk call or places an outgoing trunk call is charged with the
count on the trunk while the trunk is active in the system, even if the extension is no
longer involved in the calLThis operation can be changed so that the count is applied
to the current extension or console talking to the trunk. If the attendant handles the trunk
call first (incoming or outgoing) and transfers the trunk call to an eHension (supervised
or unsupervised), the console's message register is transferred to the extension,
Supervision on an outgoing trunk is counted as one message register count.
There are two modes of operation. The first counts the number of external calls made
by each room. The second keeps track of meter pulses being sent from the far end to
the associated trunk circuit. These pulses can in turn be charged against the guestroom
making the call.The attendant console or the front desk terminal displays the current
value of the message register for a room each time a room number is entered. The
message register can be cleared by the attendant from the console or terminal, or
automatically upon requesting an audit. (See Attendant Message Register Audit.)
Clearing the message register can be recorded as a single line report on a system
printout -the system printer prints the message register count before it was cleared.
This feature is only used in cases where COS Option 703, Message Register Applies,
has been enabled for some extensions.
The maximum message register count is 50,000. The counter resets to zero when this
count is reached (an alarm can also be generated). The alarm icon on the console can
be set to flash if the message register overflows,
Meter pulses are recorded in SMDR. See Station Message Detail Recording, Practice

Conditions If an extension with Message Registration connects to an
outgoing trunk which does not have Message Registration,
Message Registration does not apply to the extension.
When the trunk does not provide answer supervision (trunk
circuit descriptor option "Far-end Gives Answer Supervision" is
not enabled), a completed outgoing call is determined by the
pseudo answer supervision timer. This timer is started when a
trunk seizure is acknowledged and when the timer expires, a
meter pulse is counted (a pseudo answer supervision) giving an
indication of a completed external call.
