[Asterisk-Users] Strange Issue with connected TA 750

[Bisker, Scott (7805)]

Hello All,

I'm having a weird problem when connecting up to a TA 750 from adtran.  The
problem I'm seeing is that the third wire on my 66 block is behaving as the
tip (or ring) for every extension.  Is this indicative of a bad BCU?  The
only extension that works properly is extension Zap 2.   Every other
extension is crossed with Zap 2.  Very weird.

Anyone see this before?  Did I get a bum BCU?  Also, when performing a ring
test from the admin port of the 750, the same behavior is present.

Any ideas on this one?

Thanks in advance.
