He obtained patents for that simultaneous transmission, and tested the whole
approach using railway telegraph wire between Toronto and Hamilton.
Abner was a friend of the Bell family and was keenly interested in the
invention made by Alexander Graham Bell. He secured early instruments and in
1877 operated two-way and four-way circuits without an exchange and at first
without any bells. He obtained an exclusive licence for the use of the
telephone in Toronto, and in 1878 letters patent from the province for the
Toronto Telephone Despatch Company. In April 1879 the company opened the
first exchange and in June issued the first directory. In 1881 the company
was purchased by the Bell Telephone Company of Canada, which had been
incorporated by a Dominion statute of I880.
Local telephone:
His first experimental telephone use in Toronto involved the use of the wire
of the fire alarm callbox system, which allowed the use of local 'call boxes'
to call in a fire.
Since the wires were there, it made sense to try to use them for telephones as
well. He developed and patented a means of simultaneous telegraph and
telephone use of the same wire, and tested the whole process at night between
Toronto and Hamilton using railway telegraph wire . This was in 1878, and
predated the work of Van Rysselberghe.
