ABSTRACT:
The overhead format for DS1C data must be removed and the data broken into two DS1 format data signals before being transmitted over DS2 or DS3 transmission lines. The present invention demonstrates a method whereby the stuff bit code for appropriate frames of a high speed transmission line can be violated and remotely detected whereby the signal is looped back at the destination end of the desired signal whether the remote signals are in the DS1C or DS1 data format.
