Digital Mobility System Installation and Configuration Guide

The second set of LEDs on the faceplate indicate the operation status for the E1. Table 13

describes the LEDs and what status they indicate.

• On power up, all four LEDs are set to off.

• The ERR Tx is only relevant when the ALM Tx and ALM Rx LEDs are off.

• ERR Rx is triggered when the Tx ALM exceeds maintenance thresholds: BPV, CRC4, and

slip.

• ALM Tx is triggered by loss of communication with lower board (PRI board), or other internal

error.

• ALM Rx is triggered by LOS, AIS, OOF, OOM, and when the ERR Rx alarm exceeds OOS

threshold: BPV, CRC4, and slip.

• RAI transmission indicates a receive fault.

Logs and traces

Logs are available through the Logger directory in the CLI. This directory contains commands that

allow filters to be placed on the E1, for different types of errors, down to the channel level. Errors

can be stored in buffer, and then viewed or printed.

Error messages

Software error messages are available through the SWerr directory in the CLI. The errors are

stored in a cyclic buffer that can be accessed to help in troubleshooting. See “SWerr directory” on

page 77 for specific commands and details.
