Call Management System (CMS) and Basic Call Management System (BCMS)
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 use a vector-directory number 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)
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.
•
Class of Service (COS)
COS determines the class of features that a wideband endpoint can activate.
•
Facility Associated Signaling (FAS) and Non-Facility Associated Signaling (NFAS)
FAS and NFAS with or without D-Channel Backup requires administration via signaling groups
for trunk-side wideband interfaces.
•
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
Use Facility Test Calls to perform loop-back testing of the wideband call facility.
•
Generalized Route Selection (GRS)
GRS supports wideband BCC to identify wideband calls. GRS searches a route pattern for a
preference that has wideband BCC. Route preferences that support wideband BCC also support
other BCCs to allow different call types to share the same trunk group.
•
CO Trunk (TTC - Japan) Circuit Pack
The CO Trunk (TTC - Japan) circuit pack cannot perform wideband switching. No member of the
circuit pack should be a member of a wideband group.
