ABSTRACT:
High-speed digital transmission can be achieved with existing phone lines and HDSL chipsets while retaining plain old telephone service (POTS) with based on the current technology. At a receiving end, the signal is dependence upon local power. The regenerated signals are transmitted over Both HPCS cards have bypass relays for the POTS line to ensure the subscriber's POTS access in the event of a local power outage or electronic failure.
