Repair Procedure When LED Indicates Abnormality
1.1 How to check LYR LED
1. Confirm the LYR LED lights green on the front edge of the FCH (PA-FCHA) circuit card. (See “LED
Indication (A)” in Figure 6-2.) When the LED lights green, the fusion link is established.
2. Make sure that any alarm LED is not ON (red/yellow). (See LED Indication (B) in Figure 6-2.)
When all alarm LEDs are OFF, the DTI (PA-24DTR) card is in normal operation.
If any...

2.2.2 Loopback Point Designation
The DTI card can be set at one of the following loopback points:
1. Internal Loopback
All 24 B-channels sent from the TSW are looped back to the TSW at Interface on the card. At this
time, the adjacent node detects AIS signals. (See  
    in Figure 6-4.) 
2. Line Loopback
All 24 B-channels sent from the line are looped back to the line at Line Interface on the...
