This Detail Specification defines Type 9 Plenum cable used with the Token Ring LAN Cabling System. Type 9 P consists of 2 twisted pairs of Data Grade Media (DGM) shielded with aluminum tape and braided shields@ all cabled 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 equipment. OBJECTIVE The objective of the Detail Specification is to provide a document describing Type 9 P cable as a basis for certification under the NECQ system and for acquisition of conforming cable.
