Type 9 P consists of 2 twisted pairs of Data Grade Media (DGM) shielded with aluminum tape and braided shields, all cabled
12、 into a single fluorocarbon jacketed assembly. The Cabling System is intended to be compatible with IEEE Standard 802.5. It is designed to be used as a total building wiring system. The Cabling System may be used as the communications medium for a Token Ring Network as well as for other data equipme
13、nt. 1.2 OBJECTIVE The objective of the Detail Specification is to provide a document describing Type 9 P cable as a basis for certification under the KECQ system and for acquisition of conforming cable. 2.0 GENERAL DATA 2.1 GENERAL Cable provided under this Detail Specification shall conform to all
14、general and specific requirements applicable to Type 9 P cable in Omnibus Specification EIA/IS-43, Exchange Cable for Use with Data Processing Equipment, and those requirements specified herein. 2.2 ORDERING INFORMATION Orders for cable covered by this Detail Specification shall incl.ude the followi
