ABSTRACT
Numerous high-bit rate digital communication technologies are currently being proposed that employ unshielded twisted-pair (UTP) wiring. These include asymmetric digital subscriber loop (ADSL) [1, 2], high-speed digital subscriber loop (HDSL) [3], very high-speed digital subscriber loop (VDSL) [1, 4], asynchronous transfer mode (ATM) LAN [5] and broadband access [6]. While newly installed wiring tends to be fiber, it is anticipated that the data carrying capabilities of UTP will be sufficient to meet consumer needs well into the next century.
