Abstract

The invention discloses a device for switching a 63-path bridge service and a kilomega Ethernet port in an STM-1. the structure of the device comprises a first-level two-layer switching module, a second-level Ethernet two-layer switching module, a kilomega Ethernet electric port, a kilomega Ethernet optical port, an Ethernet over E1 and E1 mapping module, an SDH clock processing module, an STM-1 optical port, a VC4 bus and an Ethernet over E1 and E1 mapping module. The device for switching the 63-path bridge service and the kilomega Ethernet port in the STM-1 has the advantages of saving a lotof Ethernet category-5 cables and 75 omega coaxial cables, lowering the amount requirement of the Ethernet ports and E1 ports, reducing the occupation of stand space in a communication center machineroom, efficiently solving the problems of machine room wiring and maintaining difficulty caused by accessing too many cables, because 63 distal ends can be simultaneously accessed into the Ethernet over E1 bridge service only needing butt jointing a pair of optical fibers and an SDH transmission device and connecting one Ethernet category-5 cable with an Ethernet switch or a router. The inventionadopts the efficient, simple, convenient, low-cost accessing mode.

Description

technical field [0001] The invention relates to a network communication device, in particular to a conversion device between a 63-way network bridge service and a gigabit Ethernet port in STM-1 (Synchronous Transmission Module Level-1), belonging to the technical field of network communication devices . Background technique [0002] At present, many places use Ethernet-to-E1 bridges to access users' IP services, and E1 lines are connected to the transmission network composed of SDH equipment. The communication center computer room generally accesses a large number of remote Ethernet-to-E1 bridge services through Ethernet switches and chassis-type Ethernet-to-E1 bridge devices (see figure 1 ). The disadvantage of this solution is that it requires a large number of 75Ω coaxial cables to connect to SDH transmission equipment, Ethernet Category 5 cables to connect to Ethernet switches, occupying a lot of E1 interfaces and Ethernet interfaces of transmission equipment, and wiri...
