I'm interested in test equipment for 56k DDS and T1 lines.  I'm just
starting to investigate but I think I want gear with following
capabilities:

  Interfaces supported:

    56k DDS plain (don't care about secondary channel)

    T1 D4, ESF, B8ZS (test equip does CSU function)

    V.35

  Capabilities:

    Test pattern - transmit and receive

    Standalone loopback testing ,with one unit

    End-to-end test with two units

    Able to cause the various kinds of remote loops on T1 and DDS

    Signal quality measurements such as jitter and spectrum

    Detect T1 events such as checksum errors, bipolar volations,
    framing errors, etc.

Any other things I should be interested in?

Any suggestions on vendors other than FIREBERD?
