automatic repeat query (arq)
Use these commands to configure the Automatic Repeat Query mechanism on the modem card to
trade limited link bandwidth for redundancy in the link. The extra redundancy provides better error
correction for a more stable link. Privileged configuration access is required.
Use the no form of the command to reset the current ARQ settings to the default values.
Use the radio arq <{on | off}> command to turn on or off the ARQ feature on the link.
Use the radio arq reset command to reset the current ARQ values to consistent settings based on
the channel-parameter configuration.
NoteIf ARQ is turned off, the radio link may not get established in adverse environments.
Unless an error occurs, no notifications are displayed on the console.

Syntax Description
Example
The following command sequence sets the ARQ mechanism for 0.01% of the bandwidth, a 20
millisecond latency value, and 20 consecutive ARQ codewords.
WMCS01(boot)(config-if)# radio arq 1 20 20
pctBw Positive number representing the peak percentage of the link bandwidth to be used for
the ARQ mechanism. The value may be 1 to 10000 representing 0.01 to 100 percent of
the available bandwidth.
dataLatency Positive number specifying the expected latency value for normal data. Latency values
are measured in milliseconds.
BurstSize Positive number specifying the maximum number of consecutive ARQ codewords that
will be transmitted. Smaller values result in lower jitter.
