2.2 GENERAL PRODUCT DESCRIPTION
The Model 2090 Series T1/FT1 to V.35 Interface Converters
continue Patton’s tradition of high quality,
miniature access products.
The Model 2090 Series plugs directly into the WAN port of a switch,
router or multiplexer. The Model 2090 converts the V.35 signals to a
single T1 or FT1 connection at data rates of 1.544 Mbps (unstruc-
tured), nx64, and nx56 (n=1, 2, 3,....24). Moreover, the starting chan-
nel can be set to any value from 1 to 24. It’s a great way to connect
high speed data, video, or audio directly to T1/FT1.
The Model 2090 Series is easily configurable using pc-board
mounted DIP switches. Use the DIP switches to set D4 and ESF
framing modes, AMI or B8ZS line coding, clocking modes, Line Build
Out, Data Rate, and starting channel. Connecting directly to the V.35
interface, the ultra-compact Model 2090 attaches without using addi-
tional cables. Twisted-pair line connections are facilitated by a modular
RJ-48C jack on the rear of the unit.
Seven easy-to-read LED indicators monitor data, network, test sig-
nals, and proper setup. Model 2090 is available for 120 VAC or 100-
240 VAC Universal Interface (UI), or even DTE Interface power opera-
tion.
2.3 SUPPORTED APPLICATION
The Model 2090 allows equipment with V.35 interfaces to connect
directly to a T1/FT1 access port. The 2090 can also be used as a
high-speed short haul modem for campus applications.
2.3.1 The 2090 as the Interface between the Telco and CPE
The Model 2090 Series provides T1/FT1 connectivity between a
router and a spare port on a Frame Relay Switch (See below).
2.3.2 The 2090 as a High-Speed Short Range Modem
The Model 2090 Series can also be installed into high-speed cam-
pus applications. In this application, a pair of Model 2090 Series units
operate as short range modems (See below).
