Access network node and V5.2 interface connection starting method thereof

Abstract

The invention discloses a V5.2 interface connection starting method, which comprises the following steps of: starting a V5.2 interface; starting a first timer; judging whether variable and interface number information is received; if the variable and interface number information is received, stopping the first timer and starting a second timer; transmitting port blockage-releasing information to a local switch; judging whether port blockage-releasing feedback information transmitted by the local switch is received in a second timing period; and if the port blockage-releasing feedback information is not received in the second timing period, restarting the V5.2 interface. The invention also provides an access network node. The provided access network node and the V5.2 interface connection starting method controls the startup of the V5.2 interface connection through the first timer and the second timer, and can ensure successful startup of the V5.2 interface connection between the access network node and the local switch.

Description

technical field [0001] The invention relates to a network device and its connection method, in particular to an access network node and its V5.2 interface connection starting method. Background technique [0002] In the existing user access network, most of the network devices are connected by V5.2 interface to communicate with the public switched telephone network (Public Switched Telephone Network, PSTN) or integrated digital service network (Integrated Services Digital Network, ISDN) related business. For example, communication between a local exchange (local exchange) and a user terminal. [0003] During the communication process of the access network, abnormalities often occur due to some uncertain factors, thereby affecting the normal operation of the user terminal. For example, if there is a problem in the access network node or the local switch, the V5.2 interface connection cannot be started normally. The access network nodes or local switches work at different s...

Problems solved by technology

[0003] During the communication process of the access network, abnormalities often occur due to some uncertain factors, which affect the normal operation of the user terminal

For example, if there is a problem in the access network node or the local switch, the V5.2 interface connection cannot start normally

The access network nodes or local switches work at different system frequencies. If the V5.2 interface connection is abnormal, the V5.2 interface connection will be restarted, and the restart of the access network node and the local switch is at a different frequency. frequency, there is no guarantee of synchronization, so there is no guarantee of a successful restart

However, frequency changes between access network nodes and local switches are more inconvenient
