The UUUUU's are the test pattern coming out of the 212A at the other end.
Some sorts of "line noise" cause the automatic loopback test mode to
be entered.  If you see the UUUU's, it is not your modem doing it.  If
your modem seems to go dead, and/or has a different from normal pattern
of lights on, you may be spitting UUUUUU's at the other end.  You can disable
the automatic loopback test by pressing switch 7 of switchblock 2 (option
YL instead of the default YK).  Easy to do on your end, but usually not
too easy to get the computer center at the other end to do for you.
