A single cell power unit for a motorized surgical power tool includes a single cell power unit enclosure. A high temperature battery cell is mechanically supported within and disposed at about a center of the single cell power unit enclosure. An electrical connector having a plurality of connector pins is configured to couple to a mating electrical connector of a tool part having a motor. A motorized surgical handpiece tool which prevents the motor from operating when the power unit is removed, a method to start a multi-phase brushless sensorless motor of a surgical hand piece tool in a controlled manner, a power unit for a motorized surgical power tool with a battery insulated by a flexible circuit boards, and a safety switch system for a motorized surgical power tool with a lever magnet motor speed control are also described.

A communication device transmits very low frequency signals in order to help diagnose the cause of a communication problem in a DSL communication system. The communication problem may be, for example, the inability of a remote data transceiver unit (DTU-R) to successfully train-up with a central data transceiver unit (DTU-C). The very low frequency signals may be used to communicate the status or settings of the remote transceiver unit to the DTU-C, to download settings parameters or executable code to the DTU-R, or to coordinate the transmission of testing signals.

A system and method for communication allows a V.90 modem located at a customer premises to appear as a &ldquo;central site&rdquo; modem to a V.90 &ldquo;end-point&rdquo; modem located remotely from the customer premises &ldquo;central site&rdquo; V.90 modem. The customer premises includes a communication device that provides a four wire digital connection to the customer premises V.90 modem co-located with the communication device at the customer premises. Because the V.90 modem located at the customer premises has a four wire digital connection to a public switched network, it appears to a remote &ldquo;end-point&rdquo; V.90 modem that the customer premises V.90 modem is a &ldquo;central site&rdquo; modem. In this manner, a higher data rate is achievable from a customer premises &ldquo;end-point&rdquo; modem to either a remote &ldquo;endpoint&rdquo; modem or a remote &ldquo;central site&rdquo; modem, than is achievable from the &ldquo;end-point&rdquo; modem to the customer premises &ldquo;central site&rdquo; modem. This results in an upstream data rate approaching 56Kb/s from the customer premises &ldquo;central site&rdquo; modem to the &ldquo;end-point&rdquo; modem.
