Abstract

The invention discloses a device and a method for testing the connectivity of a 63-path bridge service channel in an integrated STM-1. The device comprises a first-level Ethernet two-layer switching module, a second-level Ethernet two-layer switching module, a kilomega Ethernet electric port, a microprocessor module, an STM-1 interface processing and Ethernet over E1 and E1 mapping module and an STM-1 optical port. The testing method comprises the following steps: realizing the isolation among 63-path bridge services by a microprocessor via the VLAN function provided by an Ethernet switching chip; carrying out a loopback operation on an STM-1 transceiver optical port by an optical fiber; carrying out packet transceiver statistic by controlling the Ethernet switching chip; and checking thestatistical result of the kilomega Ethernet port data packet transceiver. The device and the method for testing the connectivity of the 63-path bridge service channel in the integrated STM-1 has the advantages of simplifying the testing process and improving the testing efficiency of the 63-path bridge service device in the integrated STM-1, and solving the problems of long test time, large workload and the like while simultaneously detecting whether the 63-path Ethernet service channel is regular and uniquely testing each channel without an expensive Ethernet service tester.

Description

Technical field

[0001] The invention relates to an Ethernet network bridge service channel connectivity test technology, in particular to an integrated STM-1 (synchronous transmission module level-1) network bridge service channel connectivity test equipment and a 63-channel bridge service channel connectivity test method. Background technique

[0002] The 63-channel bridge service equipment in the integrated STM-1 realizes the transmission of 63-channel Ethernet services on the 155M SDH optical line, and can exchange and converge 63-channel Ethernet services to a Gigabit Ethernet interface. In the production process, it is necessary to test the connectivity of each Ethernet service channel of this device. Generally, multiple test ports provided by an Ethernet test instrument (such as SmartBits tester) are used to simultaneously send and receive Ethernet packets. The connectivity of the bridge service channel, or test each channel individually through a PC and additional equipmen...
