Can someone confirm the difference between these two Norstar Trunk Cards

I think the NT7B75 series are the ones that stick out of the cabinet,older model,while the NT5B41 are the ones that sit flush, newer card.

I can add a little to Ironhorse's comment:

The NT5B41's appear to have "made in Canada" and the NT7B75's appear to have "made in Mexico"

It makes sense that the Canada-made units would be the older originals (Nortel was Canada based) but the newer units apparently are now made in Mexico.

BUT if I mix an NT5B41GA in the same system with an NT7B75, would there be any notable difference in performance or features?

Thanks Phone People,
Ted

It's actually the older model NT5B41 that sticks out about 1/2". Either one will work and I've never had a problem with mixing cards. The older cards actually have better protection against high loop current.
