1.2 RADIO AND TV INTERFERENCE

The Model 2702 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 2702 has been tested and found to comply
with the limits for a Class Acomputing 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 2702 does cause
interference to radio or television reception, which can be determined
by disconnecting the cables, 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).

1.3 CE AND TELECOMMUNICATION APPROVALS

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

The Model 2702 is in compliance with the Telecommunication
technical requirements CRT-12; 2.048 Mbps digital unstructured
leased line (D2048U) attachment requirements for terminal equipment
interface.

2.2 GENERAL PRODUCT DESCRIPTION

The Patton Model 2702 fits into an environment where high-speed
E1/G.703 services are being offered to customers with Router/FRADS
and other networking devices. These G.703 Interface Converters are
required to convert signals from the unstructured, synchronous line
interface - delivered by the carrier - to a 2 Mbps digital interface
required by the users networking equipment.

To accomplish this, the Model 2702 presents a RJ48C interface to
the line and a V.35 interface to the customer’s device. The V.35 inter­face is presented using a Male M/34 connector. Line coding and clock
options may be selected using internally accessible DIP Switches

If other interfaces are required, you may select our Model 2703 con­verter which presents the following interfaces: X.21, RS422/530,
V.36/RS449 and V.24/RS232. These interfaces are delivered through a
standard interface cable which connects to the Female DB25 on one
end and the desired interface on the other end. If other DTE speeds
are necessary, our Model 2094 connects Fractional E1 at nx64 speeds
up to 2 Mbps. Please see the interface converter section of the Patton
Catalogue for the required converter.
