C5/K1/K3 Integrated Satellite Terminal System Operation
Rev. 0 4–71
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 can also
remotely monitor and control the remote modem by sending remote commands over the
link via the overhead. This can be accomplished by a local terminal or Monitor and
Control system.
Refer to Appendix A for more information on the Asynchronous interface with AUPC.
