Abstract

The invention provides a single net-bridge fiber-access system applied for European standard data transmission, comprising a local end centralized frame, a remote end independent box and a single E1 (European data transmission standard) net-bridge arranged in the local end centralized frame and the remote end independent box; the single E1 net-bridge comprises, in sequential circuit connection, amulti-function Ethernet conversion chip, a physical layer conversion chip, a Microprogram Controller Unit (MCU) circuit which is connected with the multi-function Ethernet conversion chip and the chip circuit, a poking switch setting circuit connected by circuit with the multi-function Ethernet conversion chip and a source input-and-output circuit connected by circuit with the poking switch circuit. The system is a part of multi-service fiber-access system, easy to be arranged, easy for operators to manage and maintain, easy to expand subsequent services, and allows traditional fixed network operators to continuously provide and expand private services.

Description

technical field [0001] The invention designs a single E1 (data transmission European standard) network bridge optical fiber access system. Background technique [0002] The changes in telecommunication networks force network operators to face enormous challenges. Business development is no longer limited to simply providing telephone services, and at least faces the following problems: [0003] 1. Remote user access: With the development of my country's vast rural economy, some villages far away from the city urgently need communication services. Telecom network operators hope to provide services to remote users without investing in additional switch nodes. [0004] 2. Centralized user access: With the rapid development of cities, there are more and more new office buildings, hotels and restaurants, and residential quarters. These areas are characterized by the concentration of users and the urgent demand for various telecommunication services. At the same time, laying c...
