Does a 56k circuit on a litespan system have to work on a OCUDP card? Can it work on a BRIU2 card? I installed a 9.6K circuit on a litespan system last year but it was on a BRIU2 card which then was terminated with an IDSL remote card locally powered in a smartjack at the subs premise and the IDSL card can be used for a 56k. An OCUDP card comes out of the system as a 4 wire circuit where the BRIU2 is 2 wire and copper pairs are in short supply due to a cable failure.
