3.0 CONFIGURATION
The Model 1180/35 uses an eight switch package that allow s
configuration to a wide range of synchronous applications. Because all
eight switches are externally accessible (see Figures 1 and 2, below),
there is no need to open the Model 1180/35's case for configuration.
3.1 DETAILED SWITCH SETTINGS
The Model 1180/35’s configuration switches set data rate
(distance), sync clock source, and DTE control of the RDL and LAL test
modes. The table on the following page summarizes the default switch
settings for the Model 1180/35. Following this table is a detailed
description of each switch function.

2.2 DESCRIPTION
The Model 1180/35 Single Fiber V.35 Short Range Modem
accomplishes full duplex, point-to-point V.35 communication over a
single multimode fiber. Supporting synchronous data rates up to 256
Kbps, the Model 1180/35 automatically adapts to hardware or software
flow control, and can be set for internal, external or received recover
clocking.
The Model 1180/35 features extended data rate circuitry that allows
for single fiber distances up to 1.5 miles at data rates above 64 kbps, or
3 miles at data rates below 64 kbps. Both local and remote loopback
tests can be activated from the front panel, or from the V.35 interface.
The Model 1180/35 front panel incorporates LED indicators for TD, RD,
RTS, CD and power.
Optical fiber may be connected to the Model 1180/35 using an ST or
SMA type interface. The V.35 DTE interface on the Model 1180/35 is a
female M/34 connector.
