Comment #6 on issue 1927 by [email protected]: Interface B->VLR http://code.google.com/p/mobicents/issues/detail?id=1927
The B interface handles signaling between the MSC and the VLR. It uses the MAP/B protocol. Most MSCs are associated with a VLR, making the B interface "internal." Whenever the MSC needs to access data regarding an MS that is located in its area, it interrogates the VLR using the MAP/B protocol over the B interface.
