1.1 RADIO AND TV INTERFERENCE
The Model 2703-X21 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 2703-X21 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 2703- X21 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 SERVICE

2.2 DESCRIPTION
The Patton Model 2703-X21 G.703/E1 Access Converter wears several hats: As an access product, the Model 2703-X21 receives unstructured, synchronous 2.048 Mbps data from a G.703 network and sends it to a router, bridge, multiplexer or other device. As an interface converter, the Model 2703-X21 accepts 120 Ohm twisted pair or 75 Ohm dual coax network connections (both types of interfaces provided). Then it converts the signals to an X.21 format on a DB-15 connector.
As a Rate Adapter, the Model 2703-X21 lets a lower bandwidth device–256 kbps, 512 kbps, or 1.024 Mbps–connect to a 2.048 Mbps G.703 link. The Model 2703-X21 supports Internal (master) or Network (slave) clocking. Loopback test is built-in, and front panel LEDs monitor power, network, master clock and test loop. Several power supply options are available.
