mec2 and kb1 cancellers when installed against a channel bank. Likely this has
been addressed by the patches incorporated into the new mg2 derivative which
attempt to deal more correctly with really wide ranging signal levels. It would
be helpful if you and/or others in the same situation could take a moment
to evaluate the performance of <A

<DIV></DIV>Just a point of reference for others, we had a lot of echo on an
Adtran Channel Bank connected to a T100P.<BR>The end poitns were all Polycom
Ip500's on a local lan connecting to *.<BR><BR>We couldn't solve the echo with
any software settings and installed a Tellabs Echo Can shelf 255D i believe
with 64ms echo cans, that resolved the problem completely.<BR><BR>No more
yelling from the secretaries :)<BR><BR>I'm
happy.<BR><BR></BLOCKQUOTE></BODY></HTML>
