We currently are using Fireberd 6000A Test sets for BERT testing. We have been noticing a substantial failure rate with these test sets and have started looking around for options.
Our major requirements are for DS1 to DS0 data rates with T1, and EIA/RS530 interfaces.
We have identified Black Box and a few other vendors with offerings.
We are looking for feedback on anyone with a favorite model they suggest we look at or avoid??
