from the network and the bandwidth resources it had been using are available
for other uses.
Retry
The Retry field value determines the number of cycles which are allowed to
pass, following the removal of a remote, before that remote is returned to the
burst map and an attempt is made to re-establish a link.
This allows, again using a mobile remote as an example, shutting down the
remote at one location, moving it to a new location, and then automatically re-
establishing a connection to the satellite network.
