Is the Metabolic Syndrome, With or Without Diabetes, Associated With Progressive Disability in Older Mexican Americans?

An asymmetric data transmission apparatus using asymmetric digital subscriber lines, which connects a high-speed data network to telephone subscriber lines in response to a demand of a subscriber, is provided. The apparatus contains subscriber line connectors which are connected to the telephone subscriber lines, which include activation sensors that receive activation signals from remote units via the subscriber lines, and which receive output signals from the remote units and output corresponding analog signals. Also, a particular subscriber line connector inputs a particular output signal from a particular remote unit via a particular telephone subscriber line and outputs a particular analog signal. The apparatus also contains subscriber modems which are connected to digital lines of the network, which modulate output digital signals transmitted from any the network via the digital lines into output analog signals, and which demodulate input analog signals into input digital signals and supply the input digital signals to the network. Also, a particular subscriber modem inputs a particular input analog signal and outputs a particular input digital signal. The apparatus also includes a connection circuit which selectively connects the particular subscriber modem to the particular subscriber line connector and which inputs the particular received analog signal and outputs the particular input analog signal.
