    This paper is a survey of the corrosion problems encountered in Bell Canada's telecommunication hardware. Specifically, the environmental attack on the outdoor metallic equipment will be addressed. These metallic parts include outdoor connectors, guy strands, lashing wires, guy hooks, cabinets, and manhole equipment. To be presented are the results of material analyses, failure analyses, field testing, and accelerated laboratory testing, which include a number of investigative programs undertaken in the previous years.
