Reframing statistics of p.c.m. multiplex transmission

The statistical properties of the reframing process in p.c.m. systems are analysed theoretically. Both expectation and standard deviation of the reframing time are expressed as functions of the framing word length, number of digits per frame, and reframing strategy parameters. Results are given both for 6.272 and 8.32 Mbit/s secondary p.c.m. telephone multiplexes.
