This article describes the ACDP broadcast messages transmitted from the AlphaCom, and give some message examples.

Broadcast messages

Message Message no, Hex Description
ST_BUSY_BC 0x0036 Broadcast message: Intercom station is busy
ST_FREE_BC 0x0037 Broadcast message: Intercom station is free
CALL_STATUS_BC 0x0040 Broadcast message telling the status of a call
CONN_STATUS_BC 0x0041 Broadcast message telling that a connection is established
DISCON_STATUS_BC 0x0042 Broadcast message telling that a connection is disconnected
EXT_FEATURE_BC 0x0043 Broadcast message when a directory number (feature 50) is dialed on a station
Q_ELEM_ADDED 0x004B Broadcast message. Reports that a mail message has been added to a station’s mail queue
Q_ELEM_REMOVED 0x004C Broadcast message. Reports that a mail message has been removed from a station’s mail queue
CONF_IS_ROOT 0x007B Broadcast message. Sender informs that it is root of conference
CONF_NOT_ROOT 0x007C Broadcast message. Sender informs that it is no longer root of conference

Message example

The messages below are broadcast messages transmitted from the AlphaCom on the AlphaCom Data Protocol when a call is initiated by the command: $CALL L8002 L8009
