Table 1 Indicator lamp descriptions for SS49OI2D,SS42OI2S,SS42SL1Q,SS42SL1O single boards
| Indicator | Status | Meaning |
|---|---|---|
| LOS (red) | Out | The single board receives the light signal normally |
| Bright | The single board does not receive the optical signal or the optical power is too low |
Metro1000 SS49OI2D Interface
SS49OI2D,SS42OI2S,SS42SL1Q,SS42SL1O single boards have SC/LC type optical interfaces on the panel for sending and receiving STM-1 optical signals.
II.Metro1000 SS49OI2D Functions and Features
OI2S/OI2D/SL1Q/SL1O single board 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 the generation of each alarm signal on the line.
SS42OI2S is a 1-channel STM-1 optical interface board.
SS49OI2D is a 2-channel STM-1 optical interface board. OI2D has two types: standalone and integrated in SCB single board.
SS42SL1Q is a 4-way STM-1 optical interface board.
SS42SL1O is 8-channel STM-1 optical interface board.
Description:
For the OI2D single board, the result of querying the DCC port number through the network management and command line is opposite to the actual optical port number.
The functions and characteristics of SS49OI2D,SS42OI2S,SS42SL1Q,SS42SL1O single boards are shown in Table 1.
