Action to take |
| READY | Flash 8 CPS | Carrier failure, BRI circuit is down. Call your carrier. They need to perform a BERT test on the circuit. If inconclusive, they must come to your site and connect with a BRI test set. |
| READY | Flash 1 CPS | PBX failure, Disconnect from NT1 to telephone system. Call your vendor. |
| ERROR | Occasional or solid Red | It's a line quality problem the carrier must fix. Call the carrier and have them run a 20 minute BERT test and send results to your vendor. |
Make sure the carrier does not test the wrong circuit. Any obtrusive test on a solid green working circuit will cause the green light to blink.
