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.
