■ Class of Restriction
Reserve a COR for AC endpoints and SDDN trunks. This restricts
endpoints that are not involved in AC from connecting to SDDN trunks or
endpoints involved in AC.
■ Class of Service/Call Forwarding
Assign to an AC endpoint a COS that blocks Call Forwarding activation at
the endpoint.
■ Data Call Setup
Do not assign a default dialing destination to a data module when it is used
in an AC.
■ Data Hotline
Do not assign a hotline destination to a data module that is used in an AC.
■ Digital Multiplexed Interface (DMI)
Use DMI endpoints as the destination in an AC. DMI endpoints do not
have associated extensions, so do not use them as the originator in an AC.
■ Facility Test Calls
The feature does not apply to access endpoints because an access endpoint
acts as an endpoint rather than as a trunk.
■ Hunting
Do not use a hunt-group extension as the origination extension of an AC.
■ Modem Pooling
If you require a modem in an AC, one is inserted automatically. If no
modem is available, the connection drops.
■ Non-Facility Associated Signaling (NFAS) and D-Channel Backup
Auto restoration for an AC that initially is routed over an NFAS facility
may fail if the only backup route is over the facility on which the backup
D-channel is administered. The backup D-channel may not come into
service in time to handle the restoration attempt.
■ Set Time Command
When you change the system time via the set time
command, all scheduled
AC are examined. If the time change causes an active AC to be outside its
scheduled period, the AC drops. If the time change causes an inactive AC
to be within its scheduled period, the switch attempts to establish the AC.
If any AC (scheduled or continuous) is in retry mode and the system time
changes, the switch attempts to establish the AC.
