Abstract: A combination of apparatus for laterally offsetting power lines from a utility pole, and maintaining the utility pole in an essentially vertical orientation and statically balanced condition.          A truss assembly is pivotally mounted to a utility pole adjacent the top thereof.  The truss includes a tubular member which extends in laterally spaced, parallel relation to a utility pole, and which receives therethrough an elongated rod adapted to securely receive and support several types of power lines.   The elongated rod includes several insulated candlesticks, or wire receiving members, on its top end, and includes several, longitudinally spaced holes formed transversely therethrough, each one of which operably receives an insulated, wire receiving bolt.  To counter-act the unbalanced load placed on the utility pole by the laterally offset power lines, a guy wire is attached at its ends to the upper and lower ends of the utility pole.   The guy wire passes around a pulley assembly which is adjustably interconnected to the utility pole.  By adjusting the lateral distance separating the pulley assembly from the utility pole, the tension in the guy wire is correspondingly adjusted.  Accordingly, by adjusting the tension in the guy wire to counter-act the unbalanced load put on the utility pole by the offset power lines, the utility pole will be maintained in an essentially vertical orientation and in a statically balanced condition.

Patent CA-2268589-A1 (CA)
Inventor: MORRIS TODD DOUGLAS
IPC: H04L12/70
Filed: 1999-04-06
Abstract: An improved access system for use in a Fiber-In-The-Loop (FITL) communications network is disclosed. The access system comprises a host digital terminal (HDT) and a plurality of subtending optical network units (ONUs). The digital signal processing (DSP) functions traditionally executed by line interface units (LIUs) within the ONUs are migrated to the HDT, rendering the individual ONUs simpler, cheaper and more reliable. This is made possible by the provision in each ONU of an oversampling codec for sampling (and conversion) of upstream and downstream data at a very high bit rate. The large bandwidths of the data communicated between the ONUs and the HDT are easily handled by the fiber optic medium therebetween. In the HDT, DSP functions are executed by a common pool, or bank, of DSP ASICs. Decimators are provided in the HDT in order to properly format the data for processing by the DSPs. Interpolators are provided in the HDT for creating a high rate bit stream that can be easily converted to analog format by a codec. A high degree of processing efficiency can be achieved by reducing complex processing tasks to a sequence of individual steps through the DSP bank and rerouting the result of each step through the bank. Such "hair pinning" can be performed in either the upstream (subscriber-to-core-network) or downstream (core-network-to-subscriber) directions.      Optionally, decimators and interpolators can be provided in the LIUs.
