Timeslot Assignment And Hold - Avaya Communication Server 1000M Single Group Manual

If the LEDs do not flash three times, unseat the card using the faceplate ejector tabs, breaking
the card's connection with the backplane. Re-insert the card and lock it in place with the ejector
tabs. If the LEDs still do not flash three times, contact a sales representative about returning
the card for repair or replacement.
Every time an MCR card boots, the self-test examines Flash memory to see if it has a good
checksum. If not, the card runs a complete Flash memory read/write test. The results of the
self-test are shown in
page 31.

Timeslot assignment and hold

The determining factor for timeslot assignment is on-hook/off-hook status. When MCR detects
a telephone going off-hook, it assigns a timeslot to that telephone. For analog cards, off-hook
status is used to indicate a need for a timeslot. For digital cards, any speaker-on state is used
to indicate a need for a timeslot; MCR assigns a timeslot to the telephone if the handset is
picked up or the handsfree mode is activated. ACD sets receive a timeslot when they are
logged in or when the headset is plugged in. When all speakers are turned off and all ACD
sets are logged off, MCR determines all timeslots to be available.
As long as the digital set is off-hook, it retains the timeslot. An MCR user may place a call on
hold, make a second call, and switch between calls. However, the call on hold is not occupying
a timeslot. If the user places the digital set on-hook while there is still a call on hold, the timeslot
is lost, but not the call. To re-establish the call, another timeslot must be available. If the MCR
user tries to access the call that was placed on hold while no timeslots are available, the user
will receive re-order but the call will remain on hold. After receiving re-order, the user may place
the call back on hold and try again for a timeslot. This may be repeated until a timeslot is
available or the caller hangs up.
