Problems solved by technology

[0003] In the existing technology, ordinary optical transmission equipment does not have the functions of multi-service support, high capacity, and easy expansion. The ordinary E1 / FE protocol converter can only transmit through E1. If optical transmission is realized, both protocol converters and optical Transmission of two types of equipment not only increases investment, but also increases the risk of failure

Abstract

The invention discloses a multi-service access SDH optical transmission device which comprises an SDH processing unit, an E1 interface processing unit, an Ethernet interface processing unit, a clock processing unit, a network management channel processing unit and the like; an E1 interface, an Ethernet interface, an STM-1 optical interface, a network management interface and the like are arranged in the system; and the system can be directly connected into a backbone network through the STM-1 optical interface, so as to form a point-to-point simple network, which accomplishes the access and transmission of E1 service and Ethernet service. The device can be further used as an E1 / FE protocol converter, and organically combines the SDH optical transmission device with the protocol converter; moreover, a network management channel setting unit can span backbone SDH to build a plurality of network management channels in a client network, thereby improving the reliability of network management communication. Furthermore, the device has flexible and diverse usage modes, and can efficiently save cost for clients.

Description

technical field [0001] The invention relates to a telecommunication device, in particular to a multi-service access SDH optical transmission device. Background technique [0002] SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) technology is the core technology of the current communication infrastructure, and the SDH equipment running on the existing network accounts for more than 80% of the total transmission system. Therefore, SDH-MSTP (Multi-Service Transfer Platform, SDH-based multi-service transmission platform) will still occupy the main position of communication network construction for a long period of time, providing richer and more economical multi-service carrying capacity. In addition, with the rapid development of IP data transmission services, using the existing abundant E1 resources in the public network to quickly build a broadband Ethernet data network has become a marketable option. [0003] In the existing technology, ordinary optical tr...
