■ Automatic Circuit Assurance
Treats wideband calls as logical single-trunk calls so that a single
ACA-referral call is made if an ACA-referral call is required. The call is
referred to the lowest B-channel associated with the wideband call.
■ Call Coverage
A wideband endpoint extension cannot be administered as a coverage point
in a call-coverage path.
■ Call Detail Recording
When CDR is active for the trunk group, all wideband calls generate CDR
records. The feature flag indicates a data call and CDR records contain
bandwidth and Bearer Capability Class (BCC).
■ Call Forwarding
You must block Call Forwarding through Class of Service.
■ Call Management System and Basic Call Management System
Wideband calls can be carried over trunks that are measured by CMS and
BCMS. Wideband endpoints are not measured by CMS and BCMS.
■ Call Vectoring
PRI endpoints can use a vector-directory number (VDN) when dialing. For
example, PRI endpoint 1001 dials VDN 500. VDN 500 points to Vector 1.
Vector 1 can point to other PRI endpoints such as route-to 1002, or route-to
1003, or busy.
Call Vectoring is used by certain applications. When an incoming
wideband call hunts for an available wideband endpoint, the call can route
to a VDN, that sends the call to the first available PRI endpoint.
■ Class of Restriction
COR identifies caller and called-party privileges for PRI endpoints.
Administer the COR so that account codes are not required. Forced entry of
account codes is turned off for wideband endpoints.
■ Facility Busy Indication
You can administer a busy-indicator button for a wideband-endpoint
extension, but the button does not accurately track endpoint status.
■ Facility Test Calls
You can use Facility Test Calls to perform loop-back testing of the
wideband call facility.
