• Connects 75 Ohm dual coax to 120 Ohm twisted pair

• Bi-Directional signal conversion according to CCITT G.703

• Data Rates up to 2.048 Mbps

• 1 U high enclosed chassis

•Reversable cover with integrated mounting ears

• Mounts in standard 19” (48.3 cm) rack

• No AC power or batteries required

•Female BNC coax or 1.6/5.6 connectors (466RC)

• RJ-45 or 64 pin amp champ 120 Ohm interface

2.2 DESCRIPTION

The Patton 464RC & 466RC G.703 balun panel matches 16 sets of
dual 75 ohm coax connections to 120 ohm twisted pair connections.
This function allows carriers to provide 120 ohm G.703 service to
customers retaining 75 ohm CPE hardware. It also allows carriers who
have standardized on 75 ohm coax to provide 120 ohm terminations to
their customers (in keeping with European ONPrequirements).

Supporting E1 data rates to 2.048 Mbps, the Patton 464RC &
466RC panels bi-directionally match signal impedance and pulse shapes
according to the CCITTG.703 standard. The Patton 464RC & 466RC
balun panels mount in a standard 19” (48.3 cm) rack.

3.0 INSTALLATION

This section describes how to connect to the twisted pair interface
and the serial interface. This section also describes procedures to
reverse the cover of the unit in order to mount the RJ-45 ports on the
front of the unit .

3.1 REVERSING THE COVER

The cover of the Balun Rack can be reversed in order to mount the
RJ-45 ports on the front of the unit, flush with the mounting ears. To
remove the cover of the unit, remove the eight screws on the sides of
the unit, lift the cover straight up, and re-attach the cover with the RJ-45
ports on the front of the unit.

3.2 CONNECTING THE 75 OHM BNC OR 1.6/5.6 COAX PORTS

The 75 Ohm BNC or 1.6/5.6 coax ports on the front of the Balun
Rack are labeled “TX” (Transmit Data Intput) and “RX” (Receive Data
Output). Simply connect the G.703 lines as follows:

Receive RX
Transmit TX

The numbers on each coax pair correspond to the RJ-45 ports on

the rear of the unit.

3.3 CONNECTING THE 120 OHM RJ-45 PORTS

The 120 Ohm balanced pairs can be accessed either by the RJ-45
ports or the 64 pin AMP Champ connector. Because RJ-45 ports and
the Amp Champ connections are in parallel, only one type of
connection should be used at a time.

3.3.1 Connecting the RJ-45 Ports

The number on each RJ-45 port corresponds to the BNC pair
numbers on the front of the unit. The pin configuration of the 120 Ohm
twisted pair RJ-45 port is shown below:

Remove screws from sides of unit.

3.3.2 CONNECTING THE 64 PIN AMP CHAMP PORT

The 120 Ohm balanced pairs can be accessed via the 64 pin AMP
Champ connector. The pins on this connector are wired directly to the
RJ-45 ports. The AMP Champ pinout is shown below.
