Nortel QSY22 Manual page 10

When a Message Center call comes in and the called DN displays, the MSG
INDIC lamp at the operator's telephone reflects the status of the called
telephone's Message Waiting lamp as follows. If Audible Message Waiting
(AMW) is equipped in place of the lamp, interrupted dial tone indicates the
called party's status.
— Steadily lit: If the operator's MSG INDIC lamp is steadily lit, the
Message Waiting indication at the called telephone is inactive.
— Fast flashing (60 ipm): If the operator's MSG INDIC lamp is fast
flashing, then the Message Waiting Indication at the called telephone is
active.
— Slow flashing (30 ipm): If the operator's MSG INDIC lamp is slow
flashing, the Message Waiting lamp at the called telephone is disabled or
not equipped. This state does not occur if the Message Waiting
Indication is by interrupted dial tone.
When an indirect message call is presented to a Message Center operator's
telephone, the MSG IN-CALLS key flashes, and both the calling DN and
called DN are displayed. If the call originated from a trunk, the route and
member number of the trunk display instead of the calling DN.
To answer the call, press the MSG IN-CALLS key. You can now take a
message or release as required.
If the caller wants to leave a message, take down the required information and
pass it on to the called party. Press the MSG INDIC key to notify the called
party that they have a message waiting.
Press the RLS key to release the call. You return to normal telephone
operations until the next Message Center call appears.
All telephones have Message Waiting capability, and any SL-1 or Meridian
digital telephone (except the M3000) can function as a Message Center. The
DN used for message taking should be the prime DN if the Message Waiting
lamp Indication and Cancellation are desired. Calls are redirected to the
telephone-type Message Center using message forwarding. Since this is a
normal DN, calls are not queued.
