1.1 RADIO AND TV INTERFERENCE

The Model 3004-MTE generates and uses radio frequency energy,
and if not installed and used properly—that is, in strict accordance with
the manufacturer's instructions—may cause interference to radio and
television reception. The Model 3004-MTE has been tested and found
to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that
interference will not occur in a particular installation. If the Model 3004­MTE does cause interference to radio or television reception, which
can be determined by disconnecting the unit, the user is encouraged to
try to correct the interference by one or more of the following measures:
moving the computing equipment away from the receiver, re-orienting
the receiving antenna and/or plugging the receiving equipment into a
different AC outlet (such that the computing equipment and receiver are
on different branches).

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive of the Union European (EU). A Certificate of Compliance is
available by contacting Technical Support.

2.2 DESCRIPTION

The Model 3004-MTE series are self-powered tail circuit buffers, which
enable the connection of two DCEs in a "tail circuit" configuration. A tail
circuit adapter is required to couple two DCE devices whose clocks are of
the same frequency but are not in phase. The Model 3004-MTE utilizes a
single auto-centering buffer to prevent data errors caused by clock jitter and
clock phase differences. All models perform the necessary "cross over"
wiring connections between the two DCEs. Installation is easy and
straightforward.

4.0 INSTALLATION

Data is transferred from the system to the tail using the system receive
clock, which is provided to the external clock input (terminal timing) of the tail
device. Data from the tail circuit is loaded into the 3004-MTE buffer using the
receive clock of the tail device. Data is transferred from the 3004-MTE buffer to
the system using the system transmit clock.

Connect the port of the 3004-MTE labeled "SYSTEM" to the main modem

or multiplexer sub-channel, i.e. the "system DCE".

Connect the port of the 3004-MTE labeled "TAIL" to the local tail-end DCE
or modem, i.e. the "tail-end DCE". The local tail-end modem must be set to
EXTERNAL CLOCK. (Local modem must accept TD data on the Terminal
Timing signal from the 3004-MTE.)

Note: The remote modem on the tail circuit must be configured for Receive
Recovered Clock (clock loopback).
