BSV interface

The BRI S/T voice (BSV) interface supports transmission of voice and data, can receive, send, compress, de-compress digital PCM voice traffic on ISDN BRI interfaces, and realizes VoIP function through other WAN interfaces of the router.

Generally, a BSV interface is used to connect an ISDN digital telephone, and also can be used as a trunk interface connecting to a PBX digital trunk. If it cooperates with an FXS or FXO interface, a BSV interface can realize flexible route selection policies for voice calls.
