Systems and methods of decoding and processing transactions for an addressable cable television tap
View Patent ↗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.
1. A method in an addressable tap for receiving signals and for providing a portion of the signals to an appropriate receiving device, the method comprising the steps of:
receiving a plurality of signals, each of the plurality of signals including an address and a command that is associated with an attached receiving device;
determining the correct attached receiving device by accessing a plurality of addresses stored in memory, wherein each address correlates with a port on the addressable tap;
storing respective received commands as flags in a queue; and
routing the portion of the signals to the appropriate receiving device,
wherein a connect command is stored as a flag in the queue after two consecutive connect command transactions are received from a head end, and a disconnect command is stored as a flag in the queue after four consecutive disconnect command transactions are received from the head end, and a port refresh command is stored for later processing if a previously received command is currently processing,
wherein a first received command for a first port is processed and a second received command for a second port different from the first port is buffered, using the flags in the queue, until the processing of the first received command is complete.
2. The method of claim 1 , wherein the processing step of the received commands utilizes system spare time.
3. An addressable tap coupled to a distribution system for controlling and splitting signals and providing the signals to receiving equipment, the addressable tap comprising:
ports for receiving an input signal and for providing outgoing signals to the receiving equipment;
a faceplate assembly having a front-end board, a power supply board, and a switchboard;
a controller for providing addressable per port switching, the controller adapted to communicate with multiple addressable ports, the controller for processing the signals and routing commands from the processed signals to an appropriate addressable port; and
a memory for storing unprocessed commands as flags in a queue,
wherein the signals include an address that is associated with each addressable port,
wherein a connect command is stored as a flag in the queue after two consecutive connect command transactions are received from a head end, and a disconnect command is stored as a flag in the queue after four consecutive disconnect command transactions are received from the head end, and a port refresh command is stored for later processing if a previously received command is currently processing, and
wherein a first received command for a first port is processed and a second received command for a second port different from the first port is buffered, using the flags in the queue, until the processing of the first received command is complete.
4. The addressable tap of claim 3 , wherein the controller is adapted to turn on or turn off a forward or reverse signal path on each port.
5. The addressable tap of claim 4 , the addressable tap further comprising a relay for enabling or disabling signals to the addressable ports.
6. The addressable tap of claim 3 , further comprising an LED status display that indicates conditions of power, receiving data, and output port status.
7. The addressable tap of claim 3 , wherein the switchboard further comprises a splitter switch combination, port powering, and status indicators.
8. The addressable tap of claim 3 , wherein the controller further comprises an address range stored in memory such that any individual addressable tap and addressable port can be remotely controlled.
9. The addressable tap of claim 3 , wherein the connect command is processed by the controller when two consecutive transactions out of six match.
10. The addressable tap of claim 3 , wherein the disconnect command is processed by the controller when four consecutive transactions out of twelve match.
11. The addressable tap of claim 3 , wherein the controller receives and processes a continuous stream of commands without dropping any commands.
