9508 SERVICE CHANNEL
The 9508 Service channel provides the means for voice communications over the power line. When
active, the service channel audio uses the entire voice bandwidth (300 - 3000Hz) of channel 0 of the
9508. At this time any audio through channel 1 of the VF-5XP used for the service channel will be
muted, and audio through channel 2 of the VF-5XP is optionally muted with the “MUTE CH2 IN SVC
CHAN MODE” setting.
When the handset at the local end is taken off-hook, the far end VF-5XP will activate a sonalert. The
VF-5XP at the far end will continue ringing until the phone is picked up or the near phone is hung up.
When the far end phone is picked up the transceivers will activate service channel mode, which is
indicated by the channel enabled LEDs turning amber. To exit this mode both phones must be hung up.
If one end forgets to hang up the service channel will remain active and the sonalert will be activated
after some delay.
