Several user- or network-programmable objects control the Automated Recovery. In 
addition to the contents of the Preset Table, these objects include the Services Recovery 
Timeout, the Network Recovery Timeout, the Recovery Iteration Time, and the Local 
Control Re-enable Timeout. The first two timeouts control how long the unit will wait after 
loss of services or network control, respectively, before entering Automated Recovery. The 
Recovery Iteration Time sets the maximum time the unit will spend attempting recovery at 
each preset. The last is a special timeout for disaster recovery, such as loss of a satellite, 
where units whose local control was previously disabled by the network are re-enabled so 
that local users may implement more complex recovery plans.

Most routine 

 operations can be performed over Wegener’s COMPEL

®

 Network 

Control System. Control is "broadcast" to individual units through a "ghost-PID" data 
component of the incoming transport stream. The 

 is considered disconnected 

from the network at any time this special stream is not being received.

In addition to the remote COMPEL network control, three methods are provided for "local" 
monitoring and control of the 

: a web browser interface (later release), a terminal 

interface (direct serial or via telnet over TCP/IP), and a front-panel interface.

Note:  Local control may be limited by COMPEL command.

The remainder of this chapter details these local monitor and control interfaces.
