SSN2SL1 Overview

The SL1 is available in several functional versions. The functions provided by the functional versions are different.

The SL1 is available in the following functional versions: R1, N1, and N2. The difference between the functional versions is with regard to whether they support the tandem connection monitoring (TCM) function and AU-3 services. The R1SL1 is a 1xSTM-1 optical interface board, which is installed in a divided slot in a subrack.

The N1SL1 is no longer manufactured.

Item	Description
Functional versions	The SL1 is available in the following functional versions: R1, N1 and N2.
Differences	Service processing: AU-3 service processing. Maintenance features: loopbacks on VC-4 paths and TCM function. Others: The R1SL1 is installed in a divided slot.
Substitution	Through the board version replacement function, the N1SL1A can substitute for the N1SL1.

NOTE:

When you configure the multiplex section protection (MSP) or sub-network connection protection (SNCP), you cannot configure the R1SL1 or N1SL1 as the protection board if the working board is the N2SL1 on which the TCM function is enabled or AU-3 services are configured. Otherwise, the services are interrupted when a switching operation is performed.

SSN2SL1 Application

The SL1 is a line board. The SL1 can be used on the OptiX OSN equipment series to transmit and receive STM-1 optical signals. The SL1 converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SL1 converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

SSN2SL1 Functions and Features

The SL1 transmits and receives STM-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.

Function and Feature	SL1
Basic functions	Transmits and receives 1xSTM-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, 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 interface of the Ve-1.2 type comply with the standards defined by Huawei.
Specifications of the optical module	Supports the detection and query of the information about the optical module. Supports the usage and detection of the small form-factor pluggable (SFP) optical module, which facilitates the maintenance of the optical module. Provides the automatic laser shutdown (ALS) function. The optical interface supports the setting of the on/off state of a laser.
Service processing	Supports the VC-12 services, VC-3 services, and VC-4 services. The N2SL1 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 channel of ECC communication.
Alarms and performance events	Provides various alarms and performance events, which facilitates the management and maintenance of the equipment.
Protection schemes	Supports the Two-fiber ring MSP, only supports two-fiber unidirectional MSP ring. Supports the Four-fiber ring MSP. Supports the Linear MSP. Supports the SNCP. Supports the SNCMP. Supports the SNCTP.
Maintenance features	Supports inloops and outloops at optical interfaces. The N1SL1/R1SL1 supports 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 N2SL1 supports the TCM function. Supports the press-to-collect function in fault data collection.

SSN2SL1 Valid Slots

The SL1 must be installed in a valid slot in the subrack. Otherwise, the SL1 cannot work normally.

NOTE:

The slots valid for a board are determined by the following factors:

Slot bandwidth
Cross-connect capacity
Board version

The slots valid for the SL1 vary with the version of the board and the cross-connect capacity of the subrack. The slots valid for the board are as follows:

When the cross-connect capacity is 20 Gbit/s:
- The R1SL1 can be installed in slots 2, 3, 6-9, 12, and 13 in the OptiX OSN 1500A subrack.
- The N1SL1 and N2SL1 can be installed in slots 12 and 13 in the OptiX OSN 1500A subrack.
- The R1SL1 can be installed in slots 1-3, 6-9, and 11-13 in the OptiX OSN 1500B subrack.
- The N1SL1 and N2SL1 can be installed in slots 11-13 in the OptiX OSN 1500B subrack.
