MPH-to-B-channel continuity test
MPH-to-D-channel continuity test
The connection between the MPH and the D-channel is tested in two steps:
1. a continuity test pattern between the MISP/BRSC with the DSL's
2. a continuity test between the MISP/BRSC with the MPH
If both tests pass, the link between the MPH and the DSL D-channel is good.
