It kinda got me too, but this *is* an active PRI with lots of users on
it, he *was* the only one causing errors and even stranger, when he
switched from the 3com TA to a NetCommander it stopped. He's since logged
in repeatedly with the NetCommander and no more errors. I wanted him to
hook the 3com box back up so I could double check the behavior but he sent
it back .... He did report the throughput on the 3com was half of what
the NetCommand does (timing ftp transfers).

Looked strange to me too, part of why I posted the message. It's got me
stumped too. As I recall, bipolar errors are encoding errors, right? Who's
doing the encoding, the CO or the TA?.

I'm watchin' them counters though :-)
