ABSTRACT:
A method of providing B channel diagnostics to an integrated services digital network (ISDN) comprises the steps of monitoring error performance on the ISDN D channel and comparing the D channel error performance to a predetermined criterion as a measure of the B channel error performance. If the predetermined threshold is exceeded any of a number of possible actions can be taken by a network diagnostics controller including various loopback tests, alerts or network reconfiguration.
