layer 2 (ANSI NCITS 308-1997), and any protocols supported by SSA-TL2 (ANSI NCITS 308-1997). The goals of SSA-PH2 (ANSI NCITS 307-1997) are: a) extending the cable distance; b) copper cable operation at 40 MB/s; c) full duplex operation to achieve an aggregate 80 MB/s between two ports; and d) other capabilities that fit within the scope of SSA-PH2 (ANSI NCITS 307-1997) that may be proposed during the development phase by the participants in the project.
