5. ALARMS
Alarms are indicated by the Low Voltage Litespan
HTU-C in the following ways:
• HTU-C DB9 control port screen alarms
• Faceplate LEDs
• Standing alarms (through direct access to the
Litespan, or remote access through a modem
connection)
The HTU-C DB9 control port screen alarms are
presented on the Current System Status and
Troubleshooting screens. Red, yellow, and blue
alarms at both DSX-1 and DS1 interfaces plus HDSL
loop synchronization loss conditions are reported.
Table C defines faceplate LED alarm functions.
TL1 provides alarm support through TL1 retrieval of
standing alarms from the Litespan database. Table D
defines the TL1 alarm conditions.
