Huawei OSN 3500 System Test Procedure

In this document, we will show you how tests SDH equipment product boards.


4xSTM-1 Optical Interface Board(S-1.1,LC)

Apply to OSN 1500B, OSN 2500, OSN 3500, OSN 7500 to transmit/receive 4xSTM-1 optical signals range at 2-15km.

Supports TCM and AU-3 services, can substituted for SSN1SLQ1A(S-1.1,LC).

Supports the detection and query of the information about the optical module.

Provides the ALS function. The optical interface supports the setting of the on/off state of a laser.

Supports the usage and detection of the SFP optical module

Supports the VC-12 services, VC-3 services, and VC-4 services, AU-3 services.

Supports the transparent transmission and termination of the path overheads.

Supports the setting and query of the J0, J1, J2, and C2 bytes.

Supports one to four channels of ECC communication.

Supports the two-fiber ring MSP, four-fiber ring MSP, linear MSP, SNCP, SNCTP, and SNCMP.

Supports inloops and outloops at optical interfaces.

Supports inloops and outloops on VC-4 paths.

Supports warm resets and cold resets. The warm reset does not affect services.

Supports the query of the manufacturing information of the board.

Supports the in-service loading of the FPGA.

Supports the upgrade of the board software without affecting services.

Supports the press-to-collect function in fault data collection.

Q: What the difference between different functional version? 

A: SLQ1 is available in two functional versions, namely, N1 and N2, The N1SLQ1 is discontinued. The difference as below:

single-fiber bidirectional optical modulesSupportedNot supported
AU-3 serviceNot supportedsupported
inloops and outloops on VC-4 pathsSupportedNot supported
TCM functionNot supportedSupported

Q: What the board substitution relation among different versions?

A: Through the board version replacement function, the N3SLQ1 can substitute for the N1SLQ1 and N2SLQ1 at the same line rate.

Q: What is the difference between different function code?


BoardFeature CodeOptical InterfaceTransmission Distance

Q: Can I change SFP module to reach longer transmission distance?

A: Yes, you can, please contact sales team, for available SFP module and cost.

Q: Can I equip different specification SFP module on different port, to perform different transmission distance for each port?

A: Yes, you can, but that not recommended.

Q: Can I use compatible SFP module on SSN2SLQ1(S-1.1,LC) board?

A: Yes, you can, the board might generate alarm, but it won’t affect use.
