2.2  GENERAL PRODUCT DESCRIPTION

The Patton Model  2715 Network Termination Unit (NTU) terminates
both 2.048 Mbps G.703 E1 (clear channel) and fractional E1 G.704 (n
x 64) 4-wire circuit. housed in our MicroPak enclosure measuring only 
9 x 5.3 x  2 cm (3.55 x 2.1 x 0.78 in.) the Model 2715 plugs directly
into the V.35 DTE interface of a router, switvh, FRAD, multiplexer or
other networking device.

The Model 2715 supports all necessary G.703/G.704 diagnostics, DTE
local/remote loops, and V.54 loop up/loop down. Diagnostics are initiat-
ed via the Model 2715's control port, or through the DTE or line inter-
faces. Easily readable LED indicators include TD, RD, Loss of Sync
(LOS), Alarm, Error, Test and Power. Configuration of the Model 2715
is done through the control port or using DIP switches.

The Model 2715 presents a RJ45 120 ohm interface to the line and a
V.35 interface to the customer's device using a Male M/34 connector.
An M/34 to DB-60 adapter cable is available for convenient connection
to Cisco routers. The Model 2715 is powered by an external Universal
Input 100-240VAC adapter.

2.3  SUPPORTED APPLICATIONS

The Model 2715 provides an E1 network termination between E1

and Fractional E1 equipment and customer premises equipment (CPE)
such as a router. The Model 2715 can also be used as a high-speed
short haul modem for campus applications.

2.3.1  The 2715 as the Interface between the Telco and CPE

The Model 2715 provides the interface between an E1/Fractional

E1 multiplexer and a router or switch (See below).

2.3.2  The 2715 as a High-Speed Short Range Modem

The Model 2715 can also be installed into high-speed campus

applications. In this application, a pair of Model 2715 units operate as
short range modems (See below).
