OSN3500 SSN1SLT1A Functions and Features
Table 1 Functions and features of the SLT1 single board

SLT1 realizes the reception and transmission of STM-1 optical signals, completes the photoelectric conversion of STM-1 signals, the extraction and insertion processing of overhead bytes, and reports the alarms generated on the line.

The specific functions and characteristics of the SLT1 single board are shown in Table 1.

Functions and Characteristics	Description
Basic Functions	Receive and transmit 12-channel STM-1 optical signals.
Optical Interface Specifications	Supports standard optical interfaces of S-1.1, L-1.1 and L-1.2. The optical interface characteristics comply with ITU-T G.957 recommendations.
Optical Module Specifications	Support optical module information detection and query. The optical interface provides laser on and off setting and laser auto shutdown function. Supports the use and monitoring of SFP pluggable optical modules, which facilitates the maintenance of optical modules. Support single-fiber bi-directional optical modules, single-fiber bi-directional optical modules do not support the use of pigtails for optical interface loopback.
Business Processing	Support VC-12/VC-3/VC-4 services.
Overhead processing	Supports segment overhead processing for STM-1 signals. Supports processing of channel overhead (transparent transmission and termination). Supports setting and querying of J0/J1/C2 bytes. Supports 1 to 12-channel ECC communication. The first eight optical ports support ECC communication in D1 to D12 channel mode, and the last four optical ports support ECC communication in D1 to D3 channel mode. Supports clock synchronization characteristics and segment overhead byte transmission time information.
Alarm and Performance	Provides rich alarms and performance events to facilitate the management and maintenance of the device.
Protection Mode	Support two-fiber multiplexing segment ring protection, four-fiber multiplexing segment ring protection, linear multiplexing segment protection, SNCP protection, SNCTP protection and SNCMP protection.
Maintenance features	Supports inner loopback and outer loopback functions at the optical port level. Supports VC-4 channel inner loopback and outer loopback functions. Support soft reset and hard reset, soft reset does not affect the service. Support the query function of veneer manufacturing information. Support FPGA online loading function. Support smooth upgrade of veneer software. Supports PRBS function, see Availability. Support one-button fault data collection.
