Southeast Asia Philippines. The eastern half of Indonesia and East Timor (east of the Wallace Line) are considered to be biogeographically part of Oceania (Wallacea) due to its distinctive faunal features. New Guinea and its surrounding islands are geologically considered as a part of Australian continent, connected via the Sahul Shelf. The region was already inhabited by Homo erectus from 1,000,000 years ago during the Middle Pleistocene age. "Homo sapiens" reached the region by around 45,000 years ago, having moved eastwards from the Indian subcontinent. Rock art (parietal art) dating from 40,000 years ago (which is currently the world's oldest) has been
56 kbit/s line 56 kbit/s line A 56 kbit/s line is a digital connection capable of carrying 56 kilobits per second (kbit/s), or 56,000 bit/s, the data rate of a classical single channel digital telephone line in North America. In many urban areas, which have seen wide deployment of faster, cheaper technologies, 56 kbit/s lines are generally considered to be an obsolete technology. The figure of 56 kbit/s is derived from its implementation using the same digital infrastructure used since the 1960s for digital telephony in the public switched telephone network, which uses a sampling rate of 8,000 Hz for PCM audio with
