Parallel Ringing is an extension to normal call with private ringing, and makes it possible to ring on several stations in parallel. Previously one had to use special hardware (the VA114D parallel connection board) to achieve parallel ringing functionality.
Example application
On board a ship the captain suite has a living room and a bedroom. There is one station in each room. When somebody calls either of the stations, both stations will ring. Captain can accept call on either of the stations with M-key or lifting handset. The bridge can use private override, and get conversation to the primary called station.
Details
The feature is supported from AlphaCom software version 10.22. The function has to be programmed using the Event Handler, using one event rule:
- Owner: Captains station (either single station, or UDP group)
- Event type: Private_Ringing_mode_(Event_Type)
- When change to: On
- Action: $PAR_RING %1.ref L111
L111 is the example Directory number of the additional station to include in ringing. Change that to the actual number to include.
Up to 10 parallel ringing stations can be added for a call. Which can be done either by a list of $PAR_RING statements in the event action text, or by a $PAR_RING with a station group reference. A $PAR_RING which includes own station is silently ignored, so it is possible to create a single rule for several stations using UDP_group.
Once the $PAR_RING action is triggered, the AlphaCom takes care of the rest: Allow accept of call from either station with M/OFF-HOOK, and disconnect stations when appropriate.
If the primary called station is busy, parallel ringing is not started. (Because the Private Ringing Event is not triggered.) If the primary station is free, and call is private ringing mode, parallel ringing is activated on the other stations which are free. $PAR_RING has no effect on stations which are busy.
