Problems solved by technology

However, because this technology only performs switching status results and time slot configuration data after switching synchronously, there is still the possibility of inconsistency between other switching information of the master cross-connect unit and the slave cross-connect unit. The received switching information is inconsistent with other cross-connect units, so that the complete synchronization of each cross-connect unit cannot be guaranteed
Especially after changing from the cross-connect unit to the main cross-connect unit, it may cause synchronization errors, which will affect the normal communication of the entire system

Embodiment Construction

[0014] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0015] The present invention proposes a new solution for the problem of inconsistency of part of the queried information when each unit of the existing joint crossover only synchronizes the time slot and the synchronous switching state, that is, the alarm required for the time slot and switching, and information such as switching bytes Complete synchronization can ensure that the service damage is minimized, and can make the information of each cross-connect unit as consistent as possible, realizing cross-connect synchronization in the true sense.

[0016] refer to figure 1 , shows a flow chart of steps of a method for synchronizing cross-connect units within a network element according to Embodimen...

Abstract

The invention discloses a cross unit synchronization method and a system in a network element. The method comprises the following steps: a master cross unit detects changes of excitation information; the master cross unit transmits the excitation information to a slave cross unit; and the slave cross unit uses the excitation information to determine the reversion state and time slot configuration data of the slave cross unit. The invention solves the problem of inconsistent information in a plurality of cross units using combined crossing, can ensure small damage to business, and can meet the requirements for reversion and the like.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for synchronizing a cross-connect unit within a network element. Background technique [0002] With the continuous increase of communication traffic, joint crossover is used more and more. Combined cross-connect means that the same service is equally split to all cross-connect units in the union, and the cross-connect units in the union perform the same time slot configuration, and the operation completes the cross-connect. This requires that each cross-connect unit in the union must maintain a consistent time slot configuration to ensure normal services, and how to better synchronize the cross-connect units of the joint cross-connect, so as to minimize service damage and make the queried information as completely consistent as possible , has become an important issue. [0003] In the time slot synchronization in the related art, the master cross unit s...
