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

Carrier failure

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.
