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 inter-
face 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 con-

verter 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.
