ABSTRACT:
Disclosed is a circuit for channel units in a digital loop carrier transmission system. Two registers include information related to the health of the channel units. One of the bits of a first register is the logical "OR" of the last four bits in the second register, thus permitting a reading of a single register to determine if any problems exist.
