Abbreviated Dialing

Use Abbreviated Dialing entries in the Destination field. Entries must comply with restrictions.

Busy Verification of Stations and Trunks

This feature does not apply to access endpoints because they are used only for data.

Call Detail Recording

For an AC that uses a trunk when CDR is active, the origination extension is the originator of the call.

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 can fail if the only backup route is over the facility on which the backup D-channel is administered. The backup D-channel might 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, Communication Manager attempts to establish the AC.

If any AC (scheduled or continuous) is in retry mode and the system time changes, Communication Manager attempts to establish the AC.

System Measurements

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