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
initiated via the Model 2715's control port, or through the DTE or line
interfaces. 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.
