Patton electronics NetLink 2720 Series User manual

One 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.
