5.2.

SELECTING THE OUTPUT MODE

The OUTPUT jumper J14, located on the center front of the module, is a three position jumper that sets
the output mode of the DA.
OUTPUT: To select the normal jitter-attenuation mode, set the jumper to the RCLK position (default).
This provides signal reclocking for the DS3 signal. The output defaults to a '1010...' test
pattern on loss of input signal.
To bypass jitter-attenuation, set the jumper to the BYP position. This position is useful for
performing system diagnostics.
Set the jumper to the PRBS position to output a '1010...' test pattern for additional diagnostics
testing.
5.3.

SETTING THE TRANSMIT LEVEL

The three LEVEL jumpers, J19, J21 and J22 located at the rear of the module beside the four output
BNCs, set the transmit level for the signal on the adjacent BNC output connector.
LEVEL: When the cable length connected to the output is less than 225 feet (68.5 meters) set the
jumper to the LOW position in order to meet the DSX-3 pulse specification.
When the cable length connected to the output is greater than 225 feet (68.5 meters) set the
jumper to the HIGH position in order to meet the DSX-3 pulse specification.
5.4. SELECTING WHETHER MODULE WILL BE CONTROLLED FROM THE
LOCAL CONTROLS OR THROUGH THE V
The MASTER jumper selects whether the module will be controlled from the local user controls or through
the VistaLINK interface.
®
MASTER: When this jumper is installed in the LOCAL position, the card functions are controlled through
the local jumpers.
When this jumper is installed in the REMOTE position, the card functions are controlled through
the VistaLINK
enabled. This LED is intended to alert the user that local controls are not currently active.
