Huawei SSN2SLO1(S-1.1,LC) Board Product Overview Huawei SSN2SLO1(S-1.1,LC) Board is 8xSTM-1 optical interface board, which realizes the access of 8 channels of STM-1 optical signals, completing the photoelectric conversion of the STM-1 optical signals, the extraction and insertion of overhead bytes, and reports various alarm signals on the line. The functional versions of Huawei SSN2SLO1(S-1.1,LC) Board optical interface board are N2 and N3. The main difference between the two versions is whether it supports TCM functions and AU-3 services. The N3SLO1 board has been discontinued. N2SLO1 supports AU-3 service processing. Support 1 ~ 8 ECC communication. Support section overhead processing of STM-1 signal. Support VC-12, VC-3, VC-4 business configuration. Support optical port-level inner loopback, outer loopback function, support FPGA online loading function. Support the query function of board manufacturing information. Support soft reset and hard reset, soft reset does not affect service. Huawei SSN2SLO1(S-1.1,LC) Board Product Feature Support I-1, S-1.1, L-1.1, L-1.2, Ve-1.2 standard optical interfaces, of which I-1, S-1.1, L-1.1 and L-1.2 optical interface characteristics conform to ITU-T G. 957 recommendations. The optical interface of Ve-1.2 is a Huawei custom standard. Support optical module information detection and query. The optical interface provides the laser opening and closing settings and the laser automatic shutdown function. Supports the use and monitoring of SFP pluggable optical modules, which facilitates the maintenance and upgrade of optical modules. SLO1 supports AU-3 business processing. Support section overhead processing of STM-1 signal. Support the processing of channel overhead. Supports the setting and query of J0/J1/C2 bytes. Support soft reset and hard reset, soft reset does not affect business. Support the query function of board manufacturing information. Support FPGA online loading function. Support smooth upgrade of single board software.
