(Manuscript received September 14, 1956) 



The design and engineering of the section of the transatlantic cable sys- 

 tem between Newfoundland and Nova Scotia were the responsibility of the 

 British Post Office. The tj-ansmission objectives for this link having been 

 agreed in relation to the overall objectives, the paper shows how these were 

 translated into system and equipment design and demonstrates how the 

 objectives were realized. 



INTRODUCTION 



Under the terms of the Agreement/ it was the responsibility of the 

 British Post Office to design and engineer the section of the transatlantic 

 cable system between Newfoundland and Nova Scotia. In common with 

 other parts of the system, all specifications were to be agreed between 

 the Post Office and the American Telephone and Telegraph Company, 

 but as both the British and the American types of submerged repeater 

 had been carefully studied and generally approved by the other party 

 prior to the agreement, the basic pattern of the system was clear from 

 the beginning. 



The service and transmission objectives for the overall connections 

 London-New York and London-Montreal were agreed- in early joint 

 technical discussions in New York and Montreal and the agreed 

 total impairments were divided appropriately between the various 

 sections. In this way, the transmission objectives for the Newfoundland- 

 Nova Scotia link were established. 



ROUTE 



The choice of Clarenville as the junction point of the two submarine 

 sections of the transatlantic system was determined primarily in relation
