RE: Problems with a PA-POS card

To keep going, not to use all of your times, but TAC couldn't figure it
out yet, either.

Light is -22 to -24 dBm to the mux and to the cards

The line2 goes:

Miami1 to Madrid

Miami2 to McLean

McLean and Miami1 get these errors:

Oct 20 16:59:20: %SONET-4-ALARM: POS8/0/0: B3 BER exceeds threshold, TC
alarm declared

and the other to get a AIS

If I loop hard without the routers in miami, madrid and McLean test fine.
I plug them in, and boom.

If I sent a loopback internal on any of the miamis they test fine, or if I
hard loop them with fiber, they test fine.

When I do loop internal on miami, the McLean one still gets the errors.
