2.2  GENERAL PRODUCT DESCRIPTION

The Model 2711 Series T1 CSU/DSUs continue Patton’s tradition

of high quality, 

miniature access products.  The Model 2711 Series

CSU/DSUs plug directly into the WAN port of a switch, router or multi-
plexer.  The 2711 

MicroLink T1™ supports a single T1 or FT1 connec-

tion at data rates of 1.544 Mbps (unstructured), nx64, and nx56 (n=1,
2, 3,....24). Moreover, the starting channel can be set to any value from
1 to 24.

The Model 2711 Series is easily configurable using pc-board

mounted DIP switches.  Use the DIP switches to set D4 and ESF fram-
ing modes, AMI or B8ZS line coding, clocking modes, Line Build Out,
Data Rate, and starting channel. Connecting directly to the V.35 inter-
face, the ultra-compact Model 2711 attaches without using additional
cables.  Twisted-pair line connections are facilitated by a modular RJ-
48S jack on the rear of the unit.  

Seven easy-to-read LED indicators monitor data, network, test sig-

nals,  and proper setup.  Model 2711 is also available for 120 VAC or
100-240 Universal Interface (UI), or even DTE Interface power opera-
tion.
