REACQUISITION

Programs the sweep reacquisition mode time duration. This is the
time that the modem will remain in a narrow sweep after loss of
acquisition. After this timer runs out, the modem will return to the
normal acquisition sweep. The reacquisition time is 0 to 999 seconds.

Upon entry, the current programmed setting is displayed with a
flashing cursor on the first character. Press [

"] or [#] to move the

flashing cursor. Press [

$] or [%] to increment or decrement the digit at

the flashing cursor. Select the number of seconds desired for the
reacquisition mode. Press [ENTER] to execute the change.

RS DECODER

(Test Mode Configuration)

Programs the Reed-Solomon decoder on, Correction off, or off.

Upon entry, the status of the Reed-Solomon decoder is displayed. Use
[

$] or [%] to select one of the following modes:

! ON: Enables the Reed-Solomon decoder to provide data

error corrections.

! CORRECTION_OFF: Turns off the Reed-Solomon

decoder data error correction circuitry. Data flow is then
routed through normal data paths without error corrections.

! OFF: The RS decoder is normally disabled (off position). To

execute any of the Reed-Solomon decoder modes, enter the
desired Reed-Solomon decoder and select the desired mode.

Press [ENTER] to execute the change.

Note: If none of the proper overhead types or data rates apply, the
Reed-Solomon decoder in the on state will be rejected (double beep).
With the Reed-Solomon decoder turned on (not off or Correction
off), the corrected BER will be reported from the outer decoder
(Reed-Solomon decoder).
