Has anyone ever done an all zeros BERT test to a remote loopback on a 3845 with a NM1-T3, or other router/T3 combo? I have a customer with a T3 that runs clean with no traffic flow, but then starts logging tons of controller errors (path-code violations, etcâ¦) when traffic is routed over it. BERT tests to a remote loopback all run clean EXCEPT for the all zero's test. Has anyone ever done an all zero's BERT across the provider's network to a remote loopback, on a T3 before? Does anyone out there have a T3 available to test that for me (it has to be across the provider network to a remote loopback)? Oh yea, a ping test with a data pattern of all zero's fails too. Very strange.
I suspect an issue with the circuit provisioning somewhere in the provider network, but don't know for sure.
Comments on folks experience with T3 BERT testing are appreciated.
Hi, scramble is a must. I don't even know why they make an option to run without.
I know these issues make everyone nervous, but ultimately it's telco problem. Either they deliver a circuit that pass for 24h BERT with all the clockbreakers, or you don't accept and don't pay.
Be reassured that telco have their own good people to call when the potato becomes hot. It's just that they never get involved initially.
