ABSTRACT:
An arrangement for monitoring slip in a digital transmission system. A PRBS sequence is transmitted in one channel or timeslot of the system. At a receiving station a characteristic group of N bits of the received sequence is assembled. The assembled group is compared with locally formed groups of N bits which would be expected to occur if a slip has occurred.
