INSIDE - OUTSIDE STATION WIRE

TIEV-CC

GENERAL
This specification covers the requirements of inside-outside station wire used for direct connection from the outside protector to the subscriber's set by The Telephone Organization of Thailand (TOT).
CONSTRUCTION :
Conductor : Solid annealed bare copper wire, 0.50,0.65 and 0.90 mm. (24,22,19 AWG) in size.
Insulation : Color coded solid high density polyethylene.
Twisted Pairs : The insulated conductors are twisted into pairs triple or quad. The four conductors of the quad shall be twisted into a " Spiral configuration with the red and green conductors diagonally four " opposite each other in the quad.
