n Send ATI4I6I7I11Y11again after 45-60 seconds online. This will show the true

“settle-in” speed, as the first thirty seconds or so might be slightly erratic.

Results of the Y11 Command.

Examine the values of 3300 and 3750 from the Y11 screen. These values indicate the

degree of “rolloff” in signal power at the high end of the frequency spectrum.

Subtract the value for 3300 and from the value of 3750. If the difference is equal to or

greater than 25, that is very good evidence of an additional analog-to-digital conversion

(codec). It is VERY likely that it is a “line-side” T1. The additional codec pair in the

path makes achieving x2 either not possible or extremely unlikely.

It is possible (though unlikely) that certain line configs, certain switch types or certain

network environments may cause problems. If there are any, we want to get to the

bottom of them immediately!! Contact U.S. Robotics Technical Support.
