Overhead processing Supports the processing of segment overhead of STM-16 signals.
Supports bytes D1 to D12, E1, E2, etc. to be configured for transparent transmission or configured to other unused overhead.
Supports processing of channel overhead (transparent transmission and termination).
Supports setting and querying of J0/J1/C2 bytes.
Supports 1 to 4-way ECC communication.
Alarms and Performance Provides rich alarms and performance events.
Kbyte processing Provides 8 sets of Kbyte processing capability.
A single optical port can support 2 MSP rings, and one SLQ16 supports up to 8 MSP (Multiplex Section Protection) rings.
REG Specification Supports the setting and querying of REG working mode.
Protection mode Supports two-fiber and four-fiber ring multiplex section protection, linear multiplex section protection, SNCP (Sub-Network Connection Protection) protection, SNCTP (Sub-Network Connection Tunnel Protection) and SNCMP (Sub-Network Connection Multi-protection). Connection Multi-protection).
Supports shared optical path protection for multiplexed segments.
Supports MSP and SNCP shared optical path protection.
Maintenance Features Supports inner loopback and outer loopback functions at the optical port level.
Supports soft reset and hard reset, and soft reset does not affect the service.
Supports the query function of single-board manufacturing information.
Supports online loading of FPGA.
Support smooth upgrade of single-board software.
Support AU3 service configuration.
