With the increasing competition in China’s backbone transmission network management market, the scale and service quality of the network become an important factor in measuring the operation of the network. Only provide unprotected transmission channels, can not meet the needs of the business network and rental circuits. Therefore, there is an urgent need to improve the level of network equipment technology and improve the reliability and flexibility of China Telecom’s primary transmission trunk network, so as to implement channel management and network recovery and channel protection for the cities above the provincial capital level and meet different user requirements for transmission bandwidth And quality of service needs.
