Asynchronous Overhead with AUPC is a closed network application that gives the user the ability
to communicate from the hub site to the remote site through the added overhead. The user can use
the AUPC feature that remotely controls the remote modem's power level, according to
parameters programmed by the user. The user also can remotely monitor and control the remote
modem by sending remote commands over the link via the overhead. This can be done by a local
terminal or Monitor and Control system.
