• Power
  • 1. If locally powered, verify the power cable installation.
  • 2. If the 12 V wall-mount power supply is used, check the supply’s cable and the circuit breaker for the 120 V receptacle the supply is plugged into.
• Network LOS
  • 1. Verify that the cable from the network demarcation is in NET modular jack on the bottom/end of the T1 CSU ACE.
  • 2. If all connections seem intact, the far end CSU ACE can be looped back (using a BERT test set to send the LB code, or using MANUAL LB at the other end) to isolate the problem to the far end customer premises or the network.
  • 3. If the problem persists after the LB has been activated, the problem appears to be within the network or the far end CSU ACE. In this case, notify the carrier.
  • 4. If the problem disappears after loop-up, then the cause must be at the far end customer premises.
• Equipment LOS
  • 1. Verify that the cable from the CPE is in the CPE modular jack on the bottom/end of the CSU ACE.
  • 2. If all connections seem intact, use a BERT test set in the NET IN and NET OUT jacks to test the CPE.
