ABSTRACT:
Methods for identifying a mis-optioned data communications circuit are provided. A test point is configured providing access to a data communications circuit for operation of a first data communications speed. A test is performed on a communications device remotely located on the data communications circuit that is incompatible with data communications at a second data speed. If the test is successful, the communications device is re-optioned for operation at the second communications speed. The test may comprise a non-latching loop back test and the communications device may comprise a network interface unit or a channel surface unit/data service unit.
