Section 68.302 (d), of the FCC rules and regulations concerning connection of terminal equipment to the telephone network an,d entitled "Metallic voltage surge" requires that the equipment be subject to "Two 800-volt peak surges of a metallic voltage (one of each polarity) having a 10 microsecond rise time to crest and a 560-microsecond minimum decay time to half crest applied between (1) tip and ring of a two wire connection ..." Other sections of these FCC rules refer to "voice band metallic signal power" and "metallic surges". Does anyone know what "metallic" means in this context? ted
