This feature is used to replace standard announcements or SIU signaling tones injected for stations on hold by individual announcement injections from external announcement devices. Configure one announcement device on a SLMA/SLMA1 board per LTG. You can assign between one and sixteen CP tones to this device.

The connection is configured using AMO SSC, TYPE=EXTANN. You must specify a PEN both when assigning the CP tones and per line. You can also assign further CP tones (max. 16)
