A Method of Uninterrupted Cutover of Telephone Network Based on Wiring System

Abstract

The invention relates to a telephone network no-interruption cutover method based on a distribution system. The method comprises a data combing stage, a data planning stage, a hardware installation and construction stage, a PTN channel building stage, and a temporary jumper building stage in order, then after 22:00 in a non-working day, a user cable outside an old distribution frame is orderly subjected to the outside of a new distribution frame, a temporary jumper is maintained, AG equipment is powered off or a user single board is pulled off, the new distribution frame inside and outside wire jumper connection is carried out, the equipment debugging is carried out, then the normal cutover is carried out, finally the data normalization and trial operation are carried out, after the trial operation of the system for a period of time, an original program-controlled exchange is powered off and removed, the temporary jumper is removed, and the cutover is completed. According to the method, the influence on existing telephone service is small, the cutover time is short, the success rate is high, and the cutover process is safe and reliable.

Description

technical field [0001] The invention relates to the field of telephone network cutover, in particular to a method for uninterrupted cutover of the telephone network based on a wiring system. Background technique [0002] PSTN (Public Switched Telephone Network: Public Switched Telephone Network) is a commonly used telephone network, which is a circuit switching network based on analog technology. NGN is the abbreviation of "Next Generation Network" or "New Generation Network", which is the fusion of PSTN voice network based on TDM (Time Division Multiplexing) and packet network based on IP / ATM product of. The main distribution frame used in the telephone network: MDF (Main Distribution Frame) for short, is used to connect subscriber lines, trunk lines, and dedicated lines to the corresponding interface points of telephone exchanges for testing, wiring and protection of intra-office equipment. The positioning of the distribution frame is a modular device that manages the fr...

Problems solved by technology

[0005] The original program-controlled switchboard equipment of the lower-level company has been in operation for many years, and it has been gradually aging. There is a lack of spare parts, maintenance is difficult, and the failure rate is increasing year by year, which does not meet the office needs of the lower-level company.
