Abstract: A full services access multiplexer is described. A master DSL modem is coupled to a conductor pair. A POTS extender is coupled to the conductor pair and may sense the operation of a fallback or other signal on the conductor pair. A suppression signal may be transmitted to the master DSL modem upon occurrence of the fallback. The suppression signal may travel over a control circuit. Traffic over a backplane or other network segment may be uninterrupted to an Integrated Access Device by handling signals inbound and outbound to the backplane via packet assembler and disassembler (PAD). The PAD may transmit a data stream to vocoder and received a data stream from vocoder for injection onto the backplane.

The vocoder connects duplexed traffic to the subscriber line interface circuit (SLIC), wherein traffic between the vocoder and the SLIC are in analog formats in or near the audible range of frequencies.

Abstract: A full services access multiplexer is described. A master digital subscriber line (master DSL) modem is coupled to a conductor pair. A POTS extender also is coupled to the conductor pair and may sense the operation of a fallback or other signal on the conductor pair. A suppression signal may be transmitted to a master DSL modem upon occurrence of the fallback. The suppression signal may travel over a control circuit.

Abstract: A full services access multiplexer (315) is described. A master digital subscriber line (master DSL) modem (303) is coupled to a conductor pair (309). A POTS extender (301) also is coupled to the conductor pair (309) and may sense the operation of a fallback or other signal on the conductor pair (309). A suppression signal may be transmitted to master DSL modem (303) upon occurrence of the fallback. The suppression signal may travel over a control circuit (305). Traffic over a backplane (307) or other network segment may be uninterrupted to a Integrated Access Device (IAD) (105) by handling signals inbound and outbound to the backplane (307) via packet assembler and disassembler (PAD) (353). PAD (315) may transmit a data stream to vocoder (351) and received a data stream from vocoder (351) for injection onto the backplane (307).

Abstract: A message priority scheme for use in local areas networks (LANS) operating in accordance with carrier sense, multiple access/collision detect (CSMA/CD) bus access protocol. A LAN station having a high priority message to send ignores the carrier sense signal, and thereby obtains immediate bus access. If the high priority message collides with another message already on the bus, both messages are subject to a backoff period. However, the backoff period for a high priority message is guaranteed to be less than that of a low priority message for a certain number of re-transmission attempts. An intermediate priority status is assigned to a message that previously had a high priority status, after a certain number of transmission attempts. The intermediate priority message is deprived of its ability to transmit while ignoring the carrier sense signal, but retains its shorter backoff period.
