Front Panel Indicators
The front panel LEDs provide status and alarm
information. There are two LED indicators on the
LIU front panel, one for each HDSL2 network loop.
See Table 2 for LED indicators.
3. TESTING
Loopback Tests
Remote Payload Loopback
T1/E1 data is looped back toward remote network
with framing and line code regenerated by the LIU.
Remote Line Loopback
T1/E1 data is looped back to the remote network with
framing and line coding unchanged.
Local Network Loopback
Customer data is looped back from the LIU.
4. MAINTENANCE
The Total Access 1000 DSLAM Dual T1/E1 LIU
requires no routine maintenance to operate properly.
In case of equipment malfunction, use the front panel
indicators to determine the trouble source.
