Systems and methods for decoding and processing back-to-back transactions for an addressable cable television tap. The addressable tap includes an input port for receiving an input signal and output ports for providing outgoing signals to receiving equipment and a controller for providing addressable per port (RF) switching. The controller is adapted to communicate with multiple addressable ports. The controller also includes storage for storing the remaining portions of partially processed commands. Further, the addressable tap includes a relay for enabling or disabling signals to the addressable output ports. Processing commands in the addressable tap includes receiving continuous commands having back-to-back transactions, from a headend and forwarding signals to receiving equipment. For a connect request, the addressable tap accepts the connect request as valid when, upon decoding each transaction, two consecutive transactions out of six are the same, and for a disconnect request, accepting the disconnect request as valid when, upon decoding each transaction, four consecutive transactions out of twelve transactions are the same.

Systems and methods of decoding and processing transactions for an addressable cable television tap

A communication system ( ) includes a tap ( ) that has an input port ( ) for receiving a signal and output ports ( ) coupled to the input port ( ) for providing the signal to subscriber equipment ( ). Each of the output ports ( ) has a programmed status comprising either an enabled status or a disabled status. After the statuses have been programmed and the output ports ( ) have been set, a controller ( ) coupled to the output ports ( ) periodically restores the programmed status of the output ports ( ) after programmed period of time, thereby automatically resetting inadvertent status changes.
