UNPRECEDENTED COMMUNICATIONS SERVICES
IN OPERATION AT THE WORLD'S FAIR

   The finest, most modern communications services available
anywhere in the world have been provided by New York Telephone at
the World's Fair.

   A network of underground cables -- long enough to stretch
four times around the world -- crisscrosses the Flushing Meadow
fairgrounds as the nerve system for unprecedented communications
services at the Fair.

Some of the services include:
  -- Touch-Tone telephones for push-button calling
  -- World's largest closed-circuit color TV network
  -- Provisions for telecasting from every part of the Fair
  -- A network of emergency telephones
  -- Advanced design telephone booths at convenient locations

   Telephone engineers began planning for the Fair four years
ago when they plodded through muddy swamplands trying to envision
the 646-acre site after its transformation into the giant spectacle
it is today.

   Estimates of communications requirements of the Fair parti-
cipants and visitors were made, and an underground conduit system
designed and installed. The conduit carries one-half billion
conductor feet of telephone cable and 150,000 feet of television
cable.

   Providing communications at all locations was not always as
routine as installing conduit and placing cable in it. For example,
to serve a boathouse on the far side of the lake, telephone installers
rented a boat, rowed across the lake, and strung cable out behind
the boat.

   A key link in the Fair's communications services is a new
switching center built in Corona last year. From this building --
which also serves nearby communities -- are channeled all World's
Fair telephone calls. Estimates are that these may average 175,000
or more a day.

   A major telephone feature provided through the building is
Centrex service for the business telephones at the Fair. Centrex
allows incoming calls to reach extensions directly without going
through a switchboard attendant.

   Public telephones at the Fair are attractive and readily
available. The 1,400 public telephones feature the Bell System's
newly developed Touch-Tone service which speeds calling by re-
placing the dial with push buttons.

   The public telephones include blue and white outdoor phone
booths called Serpentines and 10 larger family booths which permit
"hands-free" calling for groups of people. Compact "one man"
booths located throughout the Fair and in most exhibits have white
telephones on a stainless steel facing which is mounted flush to
the wall.

   Fair visitors can dial all their own telephone calls. New
operator-manned consoles called traffic service positions, have
been installed in the Forest Hills telephone building to permit
callers to dial station-to-station, person-to-person, collect and
credit card calls.

   "Ship-to-Shore" telephone service at the World's Fair
marina permits yachtsmen to make calls from their boats.

   About 300 emergency reporting telephones are located through-
out the Fair. Security guards and visitors use the telephones to
summon police, fire or medical aid. The calls go to a dispatcher
who has direct communications with the Fair's emergency services.

   Acre for acre, the Fair should be the most televised spot
on earth. Complete facilities for telecasting as many as 38
simultaneous programs have been provided. In addition, a closed-
circuit color TV network carries special events and public service
announcements to 200 receivers around the Fairgrounds.

   The job of meeting the Fair's television requirements has
been equivalent to duplicating the television facilities in mid-
Manhattan, the East Coast's major video program center.

   TV stations are able to originate telecasts from any of
62 terminal locations around the site. To provide this service,
New York Telephone installed over 28 miles of coaxial and video
cable that feed into a completely-equpped television operating
center in the Bell System Exhibit.

   Standard transmitting equipment has been repackaged for
portability, so needed transmitters can be brought to any of the
TV terminals in short order.

   The telecasts are monitored and circuits tested at the
television operating center. Activities in this main switching
station are in full view of visitors, who are able to watch six
TV monitors carrying shows in progress, as well as the technicians
responsible for proper transmission.

   From the operating center, programs are beamed to Manhattan
and thence to the nation by means of the microwave tower and
antenna, which reach 140 feet into the sky adjacent to the Bell
Pavilion. Transistorized microwave transmission equipment is
located in the glass-enclosed base of the tower.
