Training the Echo Cancellation
Overview
Line echo (also known as electric or hybrid echo) is created by the electrical circuitry connected to a twowire (full duplex) audio system. Echo is inherent in all full-duplex audio systems and is affected by the
audio line length and line impedance mismatches. The presence of audible echoes results in undesirable
audio qua lity. This kind of qual ity degradati on is inhere nt in t h e netw ork equip me nt an d e nd-u ser phone
devices.
To minimize echo, the Model LE200 performs an echo cancellation training sequence on party lines 1
through 5 . The echo ca ncellatio n training tak es approxi mate ly 15 seconds and is perf ormed aut omatically
one minute after power is applied to the LE200. This delay allows all power levels to stabilize prior to
perfor mi ng ech o c ancellation tra i ning. Echo cancellat i on can be manu all y initiated as described below.
OTE: Signal impulses are transmitted onto the audio lines during the echo cancellation training
N
sequence. Handset stations that are in use on a party line will hear the signa ls in the handset receiver. For
troubleshooting purposes, the one-minute delay may be disabled by closing DIP switch SW6-1.
Manual In itiation of E cho Cancelin g
Press and release push button PB1 on the main PC board three times. The push button must be pr essed
for at lea st one quarter second and no more than two seconds each time. The timing requirement is meant
to prevent accidental requests. If an error is made with the push-button timing, the sequence must be
repeated from the beginning.
The main board LEDs will indicate the progress of the echo canceling sequence. One column of LEDs
turns on after each push button press or release until the sequence is started. Once the sequence is started,
those LED s rema in on, and a c ountd own timer is disp layed on th e rema ining L EDs. The LED s return t o
normal op eration after the echo c ancellat ion training seque nce is complete.

Contact Closure Input Transmission
A pair of Model LE200s provides contact closure detection and transmission for five contact closure
inputs. An input contact closure on the local Model LE200 results in the corresponding output contact
becoming active on the remote Model LE200.
N
OTE: Should the data link between the two LE200s break, any active output contacts will deactivate.
Data Link Technology used with LE200 Line Extenders
The LE200 contains two different data link types for connecting line extenders. The connection scheme
of the line extenders determines which data link(s) should be used. The two data types are T1/E1 and
Low Voltage D i ffere ntial Signal ing (LVDS) . It i s possible to use both types at the same time to achieve
complex system architectures. Each data type, intended use, and the applicable switch settings are
described below.
T1/E1 Digital Lin k
The T1/E1 data link connection is the most common and is used when one pair of Model LE200s is
connected together. The T1/E1 carrier technology uses dedicated copper cable or fiber optic cable when
equipped with a T1/E1 fiber optic modem. The distance between line extenders determines the type of
connection needed. Copper wire connections require a 2-pair cable and will operate at up to 6000 feet
using No. 22 AWG wire. For distances greater than 6000 feet, a T1/E1 fiber optic modem and fiber optic
cable must be used.
OTE: The Model LE200 is NOT designed for use with the public switched telephone network.
N
Low Voltage Diff erential Signaling ( LVDS) Data Link
The LVDS data link connection is used to connect two or more LE200s located within 10 meters of each
oth er. The L VD S dat a link requ ires a straight-through shiel d e d CAT 5e cab le between line exten d ers.
Each line extender contains an LVDS data “in” port and an LVDS data “out” port. The “out” port of the
first line extender to the “in” port of the next line extender. This connection scheme is repeated to link
mult ipl e li ne ext e nd ers . Typicall y th is con ne ct io n sc heme is us ed when mu lt ip le li ne ext e nd ers ar e
installed in a central location.
Setting up the Da ta Link(s)
The data links between line extenders must be configured using multiple DIP switch settings to determine
the clock source. Each LE200 must have exactly one clock source for its main processing logic. There
ar e three choices for the cloc k: an inter nal oscilla tor, a T1/E1 clock, or the LVD S “in” clock.
There are three possible choices for the source of this clock: the local Model LE200, the remote Model
LE200, or an external clock source on the T1/E1 link connecting two Model LE200s. If more than two
Model LE200s are connected using the T1/E1 data link and LVDS data link, then all must have their
clock derived from a single source.
An unused T1/E 1 conn ect i o n can be left open (not termina t ed).

Rules for Interconnecting more than T wo 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 S eries C onnections
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 canc ellation 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.

®
• Avoid having more than one Model LE200 connected to a particular Page/Party
ca ble. Instead, use

F requently Asked Questions
Q: Why does it take so long for the propagation of off-hook to on-hook transitions?
A: The line balance ac coupling capacitors take some t ime to charge. Also, the delay helps to prevent
audio from looking like an on-hook condition.
Q: Why does it take so long for the propagation of the page line ground fault transitions?
A: If the delay was not there, then page line audio might appear to be a ground fault.
Q: I am upgrading an LE100 to an LE200, and am using a CAT 3 cable c onnection. Do I need to replace
the CAT 3 cable with CAT 5 cable?
A: No.
Q: Why is shielded cabl e sp ecified for the LVDS cab l e?
A: To improve the link’s noise immunity. Most likely, the clock signal that controls one of the LE200s
pass es over t he L V DS c ab le.
Q: Is the LE200 compatible with the public switched telephone network?
A: No.
Q: Does the LE200 have on-board prima ry protection for the T1/E1 cable?
A: No.
Q: Why is the LE200 not compatible with the public switched telephone network?
A: (1) It is not approved for such use. (2) At a minimum, it does not support the facility data link
transmission required for such use.
Q: What does LVDS stand for?
A: Low Voltage Differential Signaling
Q: Can I connect a Model LE200 to an LE100?
A: The T1 connection cannot be used to connect an LE200 to an LE100. However, an analog connection
can be used, i.e., an LE200 and an LE100 can both connect to the same system cable.
Q: Can I have Model LE100 and LE200 Line Extenders in the same system?
A.: Yes, but the LE100s must be connected to other LE100s and the LE200s must be connected to
LE200s.
Q: What happens if the line balance is not installed?
A: A loud osc illation is hea rd on t he audio line.

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 prop agation.
For copp er T1/E1 conne ctions, CAT 5 ca ble is specified instead of CAT 3 cable.
OTE: The LE200 should work with CAT 3 cable; use CAT 5 cable, or better, for all new installations.
N
• 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
same Page/Party
• 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 tha t 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 spec ifications

1. Ra pidly c hang ing co ntact inputs ma y or may not be detect e d.
2. Contact input to contact output specifications do not include the effects of relay bounce.
3. The contact input’s negative terminal is tied directly to the LE200’s signal ground.
4. Wet contact input voltages are measured at the input terminals on the 69442-xxx PCBA.
5. The “wet contact input closed voltage” may be difficult to achieve when connecting a bipolar open
collector output to a contact input.
6. A driving high wet contact input will source current to the LE200 when the LE200 is not powered.
This current may or may not prevent the LE200 from powering up properly.
7. Be aware of the ground loop (s) for me d when using wet c onta c t inputs.
