WARRANTY AND CUSTOMER SERVICE
For information regarding warranty and customer service see
the inside cover of this manual.
POWERING
The DSU 5600 is equipped with a captive six-foot power cord
that is terminated with a three-prong plug for connecting to a
grounded power receptacle.
Ensure that a grounded, 115 VAC, 60 Hz receptacle is used for power-
ing the DSU 5600.
When the DSU 5600 is plugged into an AC power source, it
performs a SELF TEST that tests all LED indicators plus various
circuit blocks within the unit. Proper operation plus failures are
indicated via the LED indicators.
CONFIGURATION
The DSU 5600 has eight options for controlling the operation of
both the network and DTE interfaces. These options are selected
by setting individual switches on the eight position DIP switch
that is accessible from the rear panel. A label of the switch
settings and their respective options is attached to the bottom of
the unit for convenience.
DTE Rate and Scrambler - SW 1, SW 2, SW 3
These three switches select the data rate for the DTE interface
and enable or disable the scrambler. As shown in Table 2-A,
combinations of up and down settings for these switches select
specific data rates and enable or disable the scrambler.
When operating at 64 kbps synchronously in Frame Relay networks the
scrambler must be disabled. When operating synchronously on a 64
kbps DDS loop not supporting Frame Relay the scrambler should be
enabled.
