A multi-service access platform access method and device

Abstract

The invention discloses an access device of a multi-service access platform. The access device is applied to a board card of an MSAP local side device and comprises an optical interface module, a PDH module, an SDH module, a determining module, a mapping module and a low-order cross module; the modules of the device are integrated on the same board card, the PDH module and the SDH module share the same optical interface, the type of the optical interface can be automatically identified through data received by the same optical interface, and therefore the access device can be adapted to far-end devices which a PDH optical transceiver and an SDH optical transceiver. On the basis of the same inventive concept, the invention further provides an access method of the multi-service access platform, when the far-end device changes, service does not need to be reconfigured, and the local side device does not need to be replaced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-service access platform access method and device. Background technique [0002] The transmission network generally adopts a three-layer structure of backbone layer, aggregation layer and access layer. With the maturity of Synchronous Digital Hierarchy (SDH) / SDH-based Multi-Service Transfer Platform (MSTP) technology, the aggregation layer of large-scale metropolitan area networks and the backbone aggregation layer of small and medium-sized metropolitan area networks SDH / MSTP ring network is mostly used for networking. However, due to the small and large number of services at the access layer, it is very sensitive to prices. Therefore, except for the use of small-capacity SDH / MSTP ring networks in occasions with high network security requirements, the access layer networks of most cities are still star-shaped Most of the connected optical transceivers are connecte...

AI Technical Summary

Problems solved by technology

In the actual use process, there may be a need to replace PDH optical transceivers and SDH optical transceivers. The conventional solution is to replace the central office equipment and remote equipment at the same time, and reconfigure the business at the same time, which brings installation and maintenance. Problems, such as when the remote end is replaced, the corresponding local end equipment needs to be replaced
