Repair Procedure When LED Indicates Abnormality
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 the figure below.) 
2. Line Loopback
All 24 B-channels sent from the line are looped back to the line at Line Interface on the card. (See
 in the figure below.)
3. Payload Loopback
All 24 B-channels sent from the line are looped back to the line at Speech Path Control Block on
the card. (See ➂ in the figure below.)

SDT Card Loopback Test
5. SDT Card Loopback Test
The patterns for loopback test, which can be set by the SDT card, are as follows:
1. Local Loopback
Loopback tests are performed only on the SDT card at the self-node.
2. Remote Loopback
Loopback tests are performed between different nodes. The result of this test can be confirmed not at the
self-node, but at the distant node.
Figure 6-14   Loopback Points of SDT Card
 Test Procedure
STEP 1: Designate the loopback test pattern by setting the P-SW key on the SDT (PA-SDTA) card (see Figure
6-15).
