Service messages provide near-end and far-end switch status. Both service
and service acknowledge messages are supported on PRI B-channels and
ISDN Signaling Link (ISL) channels. In addition, service and service
acknowledge messages for D-channels are supported between systems only.
These messages are used for backup D-channel and D-channel sanity polling.
The status may be in-service and out-of-service.
Service and service acknowledge messages for B-channels and ISL channels
are supported between systems.
Service and service acknowledge messages for B-channels and PRI are
supported only between systems, and between systems and supported Central
Office connectivities. The following are the three channel statuses reported
by the service and service acknowledge messages for B-channels and ISL
channels:
• in-service
• maintenance
• out-of-service
