Abstract
A method and system for improving the passage of silent or unused status of Ds0 channel to a data switch with a Ds0 switching capacity. The method allows the Ds0 channel source to be the only equipment that must engage a digital signal processor to remove silent and unused Ds0 channels from a Ds0 channel carrying data packet. The method provides for the Ds0 channel source, the intermediate nodes (data switches with Ds0 switching matrixes included) and Ds0 channel destination to recognize a simple and efficient means of passing suppression status of a Ds0 channel through the entire network.
Claims22
A method for removing channels from a data transmission, comprising:
- receiving a plurality of bytes of data associated with a plurality of channels;
- identifying at least one unused byte in the plurality of bytes;
- and
- generating a data packet comprising at least a portion of the plurality of bytes, the data packet including a flag indicating that the at least one unused byte has been suppressed, wherein the flag comprises one bit for each identified unused byte.
A system for removing channels from a data transmission, comprising:
- a first node configured to:
- receive a plurality of bytes of data,
- identify at least one unused byte in the plurality of bytes,
- generate a data packet comprising at least a portion of the plurality of bytes of data, the portion of the plurality of bytes of data comprising data associated with a plurality of channels, and
- attach a flag to the data packet, the flag indicating that the at least one unused byte has been omitted from the data packet and the flag identifying each unused channel in the data packet.
A method for removing channels when transmitting information over a communications network including a plurality of nodes, comprising:
- determining, by a first node, if at least one byte in a plurality of bytes to be transmitted is unused;
- generating a packet comprising at least a portion of the plurality of bytes;
- attaching a flag to the packet when the determining indicates that at least one byte is unused, wherein the plurality of bytes represents a plurality of channels and the flag identifies each unused channel;
- and
- transmitting, by the first node, the packet.
A system for removing data channels from a data transmission, comprising:
- means for determining if at least one byte in a plurality of bytes is at least one of silent or unused;
- means for generating a data packet comprising at least a portion of the plurality of bytes, the means for generating omitting each byte determined to be at least one of silent or unused;
- and
- means for attaching a flag to the data packet when at least one byte is omitted, wherein the plurality of bytes represent a plurality of channels and the flag identifies each omitted channel.
