    Need CSU Recommendation for E-1 in London

    I'm trying to help someone turn up an E-1 in London, I'm in the USA. The circuit is for voice and I want to terminate it into a MM710 E-1 Module. I just figured out that I cannot use the integrated csu functionality when configuring the blade for E-1 speeds. (Just learned the lesson about assuming things again!)

    So, I think I need to get a CSU sourced locally in London and have it configured properly and cabled properly to the MM710.

    Advice please.

    Hello there...
    were you able to hookup the E1 with integrated CSU?

    I am also running with similar issues with configuring E1(ISDN-PRI) in the Bulgaria, Europe.

    not sure whether we can use CSU(interated or other) with E1. or i may need to use normal amphenol telco cable

    Could you pls send me the signaling and trunk parameters to my e-mail id [email][login to unmask email]/email]

    So, you used normal 50pin amphenol cable( its same telco cable we use for digital/analog cards) to connect the DS1 and
