Problems with BRI service
Each LED on front of a BRI-ST or BRI-U Card corresponds
with a loop, or indicates an overall state of the BRI
connections.
The BRI card is connected to the ISDN network
(U loop) but the LED for one of more loops is not
lit
Possible problem
The physical connection or configuration for the network
connection is not correct (no Layer 1).
Solution
1. Verify the wiring from the network to the distribution
block.
2. Verify the wiring from the distribution block to the ICS.
3. Use a Meridian 2500 set to test for data on the BRI trunk.
