Functions and Features
The SLQ1 transmits and receives 4xSTM-1 optical signals, performs O/E conversion for the STM-1 optical signals, extracts and inserts overhead bytes, and generates alarm signals on the line.
Table 1 provides the functions and features of the SLQ1.
Table 1 Functions and features of the SLQ1
Function and Feature
SLQ1
Basic functions
Transmits and receives 4xSTM-1 optical signals.
Specifications of the optical interface
Supports different types of standard optical interfaces, namely, the I-1, S-1.1, L-1.1, L-1.2, Ie-1, and Ve-1.2.
The characteristics of the optical interfaces of the I-1, S-1.1, L-1.1, and L-1.2 types comply with ITU-T G.957.
The characteristics of the optical interfaces of the Ie-1 and Ve-1.2 types comply with the standards defined by .
Specifications of the optical module
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, which facilitates the maintenance of the optical module.
The R1SLQ1/N1SLQ1 supports the single-fiber bidirectional optical module, and the single-fiber bidirectional optical module does not support loopbacks at the optical interface by using fiber jumpers.
Service processing
Supports the VC-12 services, VC-3 services, and VC-4 services.
The N2SLQ1 supports the AU-3 services.
Overhead processing
Processes the section overheads of the STM-1 signals.
Supports the transparent transmission and termination of the path overheads.
Supports the setting and query of the J0, J1, and C2 bytes.
Supports one to four channels of ECC communication.
Alarms and performance events
Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
Protection schemes
Supports Two-fiber ring MSP, Four-fiber ring MSP, Linear MSP, SNCP, SNCTP, and SNCMP.
Maintenance features
Supports inloops and outloops at optical interfaces.
The N1SLQ1 and R1SLQ1 support inloops 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.
The N2SLQ1 supports the TCM function.
Supports the press-to-collect function in fault data collection.
