Title: Frame aligner monitoring system
Inventor: YAMASHITA HIROSHI
IPC: H04J3/06
Filed: 1988-12-12
Abstract: PURPOSE:To eliminate the need for a redundant bit for giving data a parity bit by performing parity arithmetic before and behind an elastic memory and comparing both arithmetic results with each other. CONSTITUTION:A parity arithmetic circuit 2 performs the parity arithmetic in one-frame units right before a received signal DIN is written in the elastic memory 1 and then writes the signal in the elastic memory 1. On a read side, on the other hand, a parity arithmetic circuit 3 performs the parity arithmetic in one-frame units and a comparator 4 compares the arithmetic results with each other to monitor the elastic memory 1. Thus, the parity arithmetic is performed before and after the elastic memory 1 and the arithmetic results are compared with each other, so the need for the redundant bit for giving the data a parity bit is eliminated.
