TAT-1 opens with 36 telephone circuits

1. Story
2. The first transatlantic telephone cable entered service between Gallanach Bay near Oban and Clarenville in Newfoundland, and was inaugurated at a ceremony in London. Its capacity was 36 simultaneous telephone circuits — the entire live voice capacity between two continents. A minority of sources give 26 September; the majority give 25 September, and this pack records the discrepancy rather than resolving it.

19. Evidence
20. Supports the TAT-1 route (Gallanach Bay near Oban to Clarenville, Newfoundland), its 36 telephone circuits and its 25 September 1956 inauguration, and the TAT-8 route, its 280 Mbit/s on two working fibre pairs, its roughly 40,000 circuits and its entry into service on 14 December 1988. V55 verification basis: retrieved by search, not opened. One retrieved source gives 26 rather than 25 September 1956 for TAT-1 entering service, and this pack records that discrepancy instead of resolving it.
