Context and question: In spring 1855, the allied British-French commanders decided to send an Anglo-French naval squadron into the Azov Sea to undermine Russian communications and supplies to besieged Sevastopol. On 12 May 1855, British-French warships entered the Kerch Strait and destroyed the coast battery of the Kamishevaya Bay.

The vast amounts of food, especially bread, wheat, barley, and rye that were amassed in the city after the outbreak of war were prevented from being exported.

Context and question: One of the first demonstrations of the ability for telecommunications to help sign language users communicate with each other occurred when AT&T's videophone (trademarked as the "Picturephone") was introduced to the public at the 1964 New York World's Fair –two deaf users were able to communicate freely with each other between the fair and another city. Various universities and other organizations, including British Telecom's Martlesham facility, have also conducted extensive research on signing via videotelephony. The use of sign language via videotelephony was hampered for many years due to the difficulty of its use over slow analogue copper phone lines, coupled with the high cost of better quality ISDN (data) phone lines. Those factors largely disappeared with the introduction of more efficient video codecs and the advent of lower cost high-speed ISDN data and IP (Internet) services in the 1990s.
What organization conducted research on ISDN phone lines?
Answer:
unanswerable
