CSU/DSU Back to Back

Discussion in 'Cisco' started by Howard Huntley, Dec 7, 2004.

  1. I have two black Box CSU/DSU MS using a crossover cable(pin 1,2 & 7,8
    crossed to 7,8 & 1,2) connected back to back in my home networking
    LAB. The boxes are still booting up in an error mode. They are not
    connected to the switch or router, just each other. The boxes are for
    DDS lines. Will they work back to back between two routers in a LAB
    setting?

    The T1 CSUs that I have used in a lab connect 1,2 & 4,5 not 7,8. I wonder
    if this is the trouble you are running into. Of course one of them needs
    to be set to line and the other clock (or internal).
