Failing test 141 is a yellow alarm which means you are not framming. Are you sure the line coding is correct? The repair proceedure is as follows:
If the MM710 connects to a line-side terminating device (for example, a PRI terminal adapter), do the following:
1. Verify that the switch DS1 and the line-side terminating device are administered using the same signaling mode, framing mode, and line coding.
2. Investigate the maintenance status of the line-side terminating device. Refer to the ’Line-Side Terminating Device Operating Manual’ for information.
3. Check the physical connection of the MM710 interface Media Module to the terminating device, and check the premise distribution system (or the intra-premise wiring) for physical connection failures.
4. Replace the local MM710 interface Media Module and repeat the test.
5. Contact the vendor of the line-side terminating device to diagnose the equipment.
Failure of test 144 is slips and the code indicates the number of slips per test interval. If you repair your yellow alarm, this should go away, otherwise repiar proceedures are:
If the MM710 connects to a line-side terminating device (for example, a PRI terminal adapter), do the following:
1. Retry the command at 1-minute intervals for a maximum of 5 times.
2. Enter the list measurement ds1-log location command
to read the error seconds measurement.
3. Verify that the switch DS1 and the line-side terminating device are administered using the same signaling mode, framing mode, and line coding.
4. Investigate the maintenance status of the line-side terminating device. Refer to the ’Line-Side Terminating Device Operating Manual’ for information.
5. Check the physical connection of the MM710 interface Media Module to the terminating device, and check the premise distribution system (or the intra-premise wiring) for physical connection failures.
6. Replace the local MM710 interface Media Module and repeat the test.
7. Contact the vendor of the line-side terminating device to diagnose the equipment.
I agree with dimas that troubleshooting should start with a loop-back to both systems to eliminate cable and/or hardware faults.
