Title: Signal error information management for synchronous digital hierarchy system
Inventor: KIM JI HUN
IPC: H04L12/43
Filed: 2001-12-22
Abstract: PURPOSE: A signal error information managing method of a synchronous multiplexing equipment is provided to detect a position of an abnormal signal generated from an SDH(Synchronous Digital Hierarchy) network by using a preliminary byte of an MSOH(Multiplexer Section Overhead) of an SDH signal. CONSTITUTION: A synchronous transmitter interprets an SDH signal received from a remote station to detect a signal error state(S310). The synchronous transmitted checks a signal error of a local station(S320). The synchronous transmitter compares a level of the signal error received from the remote station and a level of the signal error generated from the local station(S330). If a priority of the signal error state received from the remote station is higher, the synchronous transmitter maintains an overhead Z1 byte of the received signal as it is(S340). If a priority of the signal error state of the local station is higher, the synchronous transmitter updates signal error information of the overhead Z1 byte of the received signal with the ID and the type of signal error state of the synchronous transmitter(S350). When the ID and the updating or maintaining of the signal error state information of the local station or the remote station is determined at Z1, parities of preliminary units Z11 and Z12 where the information is to be loaded is checked(S360). When the SDH signal is transmitted and received, it is checked whether Z1 byte is an even parity(S370). If Z1 byte is not an even parity, the foremost bit of the preliminary bytes Z11 and Z12 is set as a parity compensating bit(S380) and the value is changed to make entire Z1 type be an even parity and stored in the Z1 byte(S390), and then, an SDH signal loaded with the overhead including it is transmitted(S400).
