The PRISM 4101 can not transmit alternating DSU loop code or cause sealing current
reversal to activate a loop on the remote end unit.

loop code to the remote end causing the remote unit to enter a V.54 loop. Refer to
the section entitled V.54 Loop on page 18 for specific information concerning the
V.54 loop.
