Changing to a LE200 from a LE100
Changed Features Compared to LE100
An echo cancellation routine is added.
The LE200’s off-hook detector must be the only off-hook detector installed on a particular party line.
The LE200 supports only unidirectional off-hook propagation, while the LE100 supported bi-directional
off-hook propagation.
For copper T1/E1 connections, CAT 5 cable is specified instead of CAT 3 cable.
N
OTE : The LE200 should work with CAT 3 cable; use CAT 5 cable, or better, for all new installations.
• The LE200 provides true relay outputs instead of polarized solid-state relay outputs.
• The LE200 is not able to connect to the LE100. The LE200 pairs must replace the LE100 in pairs.
• There exists an additional consideration related to echo cancellation when connecting Model LE200s
in series.
New Features Compared to LE100
• The LE200 has a LVDS interface expected to be used to avoid paralleling multiple LE200s on the

cable.
• Page line ground faults can be propagated from the remote connection.
• The LE200 can report remote page line ground faults.
• The LE200 has an array of LEDs that can sometimes aid in troubleshooting.
• The LE200 has isolation relays that disconnect it from its (audio line) field wiring when it is not
powered.
• The LE200 has the ability to select either T1 or E1 signal specifications
