VCB

voice conference bridge

The voice conference bridge application provides a simultaneous communication path between two or more voice circuits. VCBs are deployed in a central location with remote devices connected to the bridge via an NE over an IP/MPLS or TDM network. Inputs to the VCB are 4-wire E&M analog interfaces.

VCBs can be used as a conference bridge with any-to-any connectivity (all branches participate) or as a bridge in broadcast mode where one branch broadcasts to the other branches that are in listen-only mode.
