Indicator Lamps
The SLE/SDE single board panel has indicator lights that indicate single board alarms, and the description of the indicator status is shown in Table 1.
Table 1 Indicator lamp descriptions for SLE/SDE single boards
| Indicator | Status | Meaning |
|---|---|---|
| LOS (red) | Out | The single board receives STM-1 electrical signals normally. |
| LIGHT | No STM-1 signal is received by the single board. |
Interface
The STM-1 electrical interface of the SLE/SDE board is on the panel and is an SMB type coaxial connector. The number on the connector indicates the serial number of the interface, Tx for transmitter and Rx for receiver.
Functions and Characteristics
The SLE/SDE single board realizes the reception and transmission of STM-1 electrical signals, completes the overhead byte extraction and insertion processing of STM-1 signals as well as the generation of each alarm signal on the line.
The functions and features of the SLE/SDE single board are shown in Table 1.
Table 1 Functions and characteristics of the SLE/SDE single board.
