Rules for Interconnecting more than Two Model LE200s
When connecting more than two Model LE200s together, these rules must be followed.
• A maximum of two Model LE200 pairs can be connected in series when the series connections are
made using Page/Party ® cable as shown below.
Figure 13. Maximum Series Connections
When Model LE200s are connected in series, a problem can arise when training echo cancellation. If
more than one Model LE200 is training echo cancellation on a signal line at the same time, then none
of them will train echo cancellation properly. To prevent this, power each line extender one at a time.
Wait for the echo cancellation to complete on the first line extender before powering the second.
• A maximum of eight pairs of Model LE200s can be connected in parallel. Parallel connections must
be made using the LVDS link and the T1/E1 link as shown below.
