Compression settings for the modem are specified here in the number of pack-
ets. Header compression and Payload compression are enabled/disabled on a
per route basis, as described in the section “Creating the Static Routes” on
page 4-16.
This feature only applies to units that have modulators. The parameters are not
applicable to CDD-880 units or to Expansion units, since all demodulators will
automatically detect compressed packets that are received and perform decom-
pression.
