CANTAT-1
CANTAT-1 was the first Canadian transatlantic telephone cable, between Hampden, Newfoundland and eventually Grosses-Roches, Quebec and Oban, United Kingdom, which followed on from the success of TAT-1.[1][2] It was conceived and approved as stage one of a proposed commonwealth round the world cable and was done at a cost of $8,500,000.[3] The system was jointly owned by Cable & Wireless and the Canadian Overseas Telecommunication Corporation (COTC).
The system, involving the first commercial use of a new lightweight deep sea cable with a weight in water of about one-fifth that of armored deep sea cable, was laid in two phases. The first, CANTAT A, was the Template:Cvt ocean section laid by HMTS Monarch with the U.K. shore end laid by HMTS Ariel[note 1] and the Canadian end laid by the U.S. Army CS Albert J. Myer. The second phase, linked by overland cable from Hampden to Corner Brook, Newfoundland, was the Template:Cvt segment laid by HMTS CS Alert[note 2] with both shore ends laid by CS Hadsund.[1][2]
The new Trans Atlantic cables, TAT-1, CANTAT-1 and TAT-2, with their high capacity brought about a major change in regulations, with specific changes in the U.S. Federal Communications Commission policies regarding lease of foreign cable channels by U.S. international record carriers.[note 3][3] CANTAT-1 operated from 1961 to 1986, initially carrying 60 telephone circuits, later modified from 4 kHz channels to 3 kHz channels, expanding capacity to 80 telephone circuits.[1][2]
