Abstract
A telecommunications device includes a sender coupled to a local area network. The sender generates a message packet including an arbitration code and a data packet and communicates a first value of the arbitration code using the network. The sender determines a network value and compares the first value with the network value to determine whether the sender may communicate the data packet using the network. The arbitration code may further include a message priority code and a sender address. In another embodiment, the message packet further includes a destination code according to which the sender communicates the data packet as a point-to-point, multi-cast, or broadcast message.
Claims22
A telecommunications device, comprising:
- a local area network;
- a sender coupled to the network and operable to generate a message packet comprising an arbitration code and a data packet, the sender operable to communicate a first value of the arbitration code using the network and to determine a network value, the sender operable to compare the first value with the network value to determine whether the sender may communicate the data packet using the network;
- and
- a plurality of receivers also coupled to the network, the message packet further comprising a destination code having values for a plurality of positions, each position corresponding to a particular receiver independent of the value for that position, the sender identifying one or more receivers for the message packet according to the values of the positions corresponding to the receivers,
- wherein each receiver has an associated receive code comprising values for a plurality of positions, each position corresponding to a particular receiver independent of the value for that position, each receiver operable to receive the destination code and to compare the value for at least one position of the destination code with the value for at least one position of the receive code, each receiver operable to determine whether to receive the data packet according to the comparison.

A method of communicating a data packet using a local area network within a telecommunications device, comprising:
- generating a message packet comprising an arbitration code, the data packet, and a destination code having values for a plurality of positions, each position corresponding to a particular receiver independent of the value for that position;
- identifying one or more receivers for the message packet according to the values of the positions corresponding to the receivers;
- communicating a first value of the arbitration code using the network;
- determining a network value;
- comparing the first value with the network value;
- determining whether to communicate the data packet using the network;
- receiving the destination code;
- comparing the value for at least one position of the destination code with the value for at least one position of a receive code, the receive code associated with a receiver and comprising values for a plurality of positions, each position corresponding to a particular receiver independent of the value for that position;
- and
- determining whether to receive the data packet according to the comparison.

- identifying one or more receivers for the data packet according to the values of the positions corresponding to the receivers;
- communicating the data packet to the identified receivers using the network;
- receiving the destination code;
- comparing the value for at least one position of the destination code with the value for at least one position of a receive code, the receive code associated with a receiver and comprising values for a plurality of positions, each position corresponding to a particular receiver independent of the value for that position;
- and
- determining whether to receive the data packet according to the comparison.
