ACTIVATION/USE
P.K.: Programmed Key – defined by MMC-PM5 (Expert View) or MMC-Station
S.K.: Soft Key
Code: Code programmed in the "Features in Conversation" table
(*) When a line in the trunk group is released, the subscriber requesting callback is rung. When he
picks up the handset, he hears the dial tone. He then needs simply to dial the number without entering
the trunk group number.
When the automatic callback request was left following an automatically dialed call (by personal speed
dial, for example), the dialing is transmitted automatically by the system once the requester has answe-
red the callback.
