Administered Connection 

■

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.

■

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.

■

Modem Pooling

If you require a modem in an AC, one is inserted automatically. If no 
modem is available, the connection is dropped.

■

Non-Facility Associated Signaling (NFAS) and D-Channel Backup

Auto restoration for an AC that is initially 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 

ACs are examined. If the time change causes an active AC to be outside its 
scheduled period, the AC is dropped. 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.

■

System Measurements

Access endpoints are not measured. All other trunks in an AC are measured 
as usual.
