| Functions and Features |
Description |
| Basic Functions |
16-channel STM-1 signal processing board. |
| Optical module specifications |
- Support optical module information detection and query.
- Support optical interface to provide laser on and off setting and laser auto shutdown function.
- Supports the use and monitoring of SFP pluggable optical modules, which facilitates the maintenance and upgrading 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 16-channel ECC communication. The first eight optical ports support ECC communication in D1 to D12 channel mode, and the last eight optical ports support ECC communication in D1 to D3 channel mode.

Table 2 Comparison of access capacity when SLH1 board is matched with different outlet boards and electrical interface reversing boards
SLH1 single board is a 16-channel STM-1 signal processing board, which accomplishes STM-1 optical/electrical signal processing.
The specific functions and characteristics of the SLH1 single board are shown in Table 1.
When SLH1 board is used with different outlet boards and electrical interface protection inversion boards, it has different access capabilities for STM-1 signals, as shown in Table 2.
| Use with Single Board |
Function Description |
| None |
