There are several things we need to look at here. In a point to =
point T-1, all of the multiplexers and digital cross connects are =
transparent, ie. they pass whatever is sent to them without regard =
to timing. This is why you must provide clock on one end (the A =
end in the ckt design) and receive clock on the other end (the Z =
end of the ckt design).=20
If you have 2 CSU/DSU's set to either both provide or both receive =
timing, you will see slips as a result of the 2 closck fighting =
each other. The quality of the clock determines how many slips in =
a certain time period you could expect to receive. For instance a =
stratum 2 clock is more stable (less slips) than a stratum 3.=20
If I were you (and keep in mind I toubleshoot more T-1's before =
9am than most people do all day :-) ), I would use the tools you =
have (the Adtrans) and check for errors on the span. The various =
alarms are going to help pinpoint where the problem lies. Pull the =
stats and alarm history and e-mail them to me.
