O

ne of the smallest and most economi-

cal CSU/DSUs available, the Model

2720 is loaded with features usually

found in more expensive units: flexible clock-

ing modes, AMI/B8ZS coding, diagnostics,

and nx56/nx64 rates—all easily configurable

through switches or VT-100 console.

The Model 2720 series terminates T1/FT1

services for all nx56/nx64 kbps to 1.544

Mbps rates and connects to the customer’s

router, FRAD, CODEC, and LAN with V.35, RS-

530, or 10Base-T interfaces. Front panel

LEDs and switches allow for instant diagnos-

tics and service monitoring. Use the VT-100

console port for complete command and con-

trol over your T1 termination. AC or DC power

options make installing the Model 2720 into

your network infrastructure a snap.

The wide variety of fea-

tures, compact size, and

low price make Patton’s

T1 CSU/DSUs the right

solution for your next

network challenge.
