slip seconds will cause problems with echo and other voice anomalies. Depending
on Router Chassis, Cards and configuration of where any other clock sources are
coming from this can be very easy or very difficult to fix. On this T-1 since it
is set to receive clock from the line, is the other side infact set to generate
clock, and if so where is it generating the clock signal
from?</FONT></SPAN></DIV>
