Abstract
An apparatus for converting frame-type transmissions to packet-type transmissions. In one embodiment, the apparatus comprises a medium access controller (MAC) coupled to a packet-based network and multiple packet assembler/disassemblers (PADs). The PADs include a data link layer (DLL) PAD coupled to the MAC, a high level data link control (HDLC) PAD coupled to the DLL PAD, a network layer (NL) PAD coupled to the DLL PAD, and a NL/frame alignment sequence-bit-rate allocation signal (NL/FAS-BAS) PAD coupled to the DLL PAD. Multiple detection units are coupled to respective PADs, wherein each of the plurality of detection units detects a frame-type transmission.
