This sounds like you might have the unit set to clock from the IRX which
does not generate clock. MCI should be generating the clock and
everything else should slave to it.

Hmmm. Blows that idea I guess.

Is the cisco configured for encapsulation PPP or defaulted to HDLC? The
IRX needs PPP so if MCI is sending HDLC it would work on the cisco and not
the IRX.

I normally run with modem control on but you have no DCD right now so that
won't change anything. There is something not right with the TSU that is
isn't showing DCD or with the port or cable(s). Try it on S3 if this is a
IRX-114. Perhaps there is something wrong with the S1 port.
You probably already thought of the above. Best wishes.
