PRI Gateway span usage

The PRI Gateway allows flexible configuration DCH interface and B-channels on the E1/T1
card.
For some interface types, the PRI Gateway also supports a nB+D feature by having a single
D-channel interface (attached with DDCH daughterboard) support several E1/T1 spans.
Therefore, it is possible that one span is not configured with any DCH interface but is used for
B-channels which are served by D-channel interface defined in another span.
