Abstract

The invention provides an automatic selection method of internal time slot of SDH (synchronous digital hierarchy) equipment. The automatic selection method includes uniformly numbering information sources of crossover information and sink ports of a TST low-order crossover network of the SDH equipment; traversing S-grade control storages of the TST low-order crossover network and allocating available spare time slot z for cross connection point (x, y) which is configured newly; selecting an internal time slot from the spare time slot z to perform service configuration; according to mode of TST network configuration and the selected time slot, completing write operation of the TST network control storages to achieve increment issue service. The failure of issue caused by network congestion during the increment issue service on the condition of the spare time slot existing in the TST low-order crossover network is avoided, the circumstance of achieving the issue service on the premise of multiple attempts on the condition of random allocation of time slot is avoided, and service configuration efficiency is increased effectively.

Description

technical field

[0001] The invention relates to a low-order cross network in a Synchronous Digital Hierarchy (SDH) optical transmission system, in particular to a method for automatically selecting an internal time slot for service configuration of a TST low-order cross network in SDH equipment. Background technique

[0002] SDH sites, which are widely used in transmission networks, are the basis for carrying various communication services. In the SDH network site, the cross-connect module is the basis for service configuration. It distributes the services on the line board and the tributary board. ring. In the application of the cross-connection function of the service configuration on the live network, sometimes the service configuration interface shows that there are free time slots, but the internal block occurs when the new service configuration is incrementally delivered, and the delivery fails.

[0003] When the above problems occur, the operator usually observes th...
