Abstract
A host digital terminal (118) receives telephony traffic from a time division multiplexed (TDM) switch (122) and packet data asynchronous transfer mode (ATM) cells containing packet data information from an ATM switch 116. The host digital terminal (118) converts the telephony traffic into telephony ATM cells (34) and multiplexes the telephony ATM cells with the packet data ATM cells for placement into a synchronous optical network (SONET) frame (38). The host digital terminal (118) transports the SONET frame (38) to an optical network unit (124). The optical network unit (124) demultiplexes the telephony ATM cells (34) from the packet data ATM cells in the SONET frame (38). Packet data information within the packet data ATM cells is extracted and provided to a monitor (132) through a network terminator (126) and a computer or set top unit (130). Telephony traffic is extracted from the telephony ATM cells (34) and provided to telecommunications equipment (128) through the network terminator (126).
