SYSTEM AND METHOD FOR PROVISION OF OPERATION OF HIGHER PERSISTENCE NETWORK WITH REMOTE ACCESS Russian patent published in 2010 - IPC H04L12/66 

FIELD: information technologies.

SUBSTANCE: high persistence substation includes multiple joined packet network devices, at the same time substation of high persistence is able to operate in the first mode, where the main stations provides services of centralised processing of telephone calls by means of connection between substation of high persistence and main station to high persistence substation. High persistence substation is also able to operate in the second mode, when connection between high persistence substation and main station is broken. In process of operation in the second mode, multiple joined packet network devices jointly provide services of distributed processing of telephone calls to high persistence substation. In some cases network devices represent packet single-range terminal sets, at the same time, when connection to main station is lost, the terminal sets themselves, operating in single-range mode, are able to jointly provide required services of telephone communication, which are usually provided by the main station.

EFFECT: increased reliability of communication under conditions of power supply disturbance or fault in network.
