Abstract :
The Type O carrier is an economical short-haul carrier system especially suitable for use under 150 miles. It fulfills the same purpose for open-wire lines as the Type N carrier system does in cable routes. Numerous laboratory tests have indicated that good service standards have been maintained in spite of its low cost.
