PAGE TWENTY-SIX THE DAILY TIMES-GAZETTE SATURDAY, APRIL 28, 1983 New Dial Exchange Building Houses Latest Equipment Many New Subscribers Added To Local Service With New Dial Exchange A large number of people will be getting Oshawa tele- phone service for the first time as a result of the conversion of Oshawa's telephone system to dial operation, according to A. A. Gillespie, Bell Telephone manager here. Approxi- mately 235 of the present 800 people waiting for telephones will get service at the time of the cutover, Mr. Gillespie said. In addition, about 250 subscribers in suburban areas who are now receiving rural service will be provided with urban ser- vice for the first time. Dial equipment installed in the® new exchange building at the cor- ner of Bond and Victoria Streets consists of 12,500 terminals, each terminal representing a telephone number. This represents an ex- pansion in central office facilities of some 30 per cent. In addition, an extensive outside wire and cable program to be un- der-taken in the city this summer will result in most of the remainder of those waiting for service getting telephones this fall. This work will include the erection of 70 telephone poles and 21,000 feet of aerial cable and the placing under- ground of 8,900 feet of cable. Extensive construction of wire and cable was recently completed in the rural area served by the ex- change. This project reduced the number of rural subscribers per line to a maximum of 10, reliev- ing congestion of the equipment and improving service, and also provided facilities for subscribers in the rural territory in the north, west and east section of the ex- change where certain suburban de- velopments will be brought within the urban territory served by the Oshawa exchange at the time of the cutover. This rural expansion involved the construction of nearly 16,000 feet of aerial cable to the north of Ross- land Road alone, in addition to which some 12 miles of wire was erected on pole lines throughout the northern fringe of the rural area, Extensive cable construction was also carried out from Rossland Road south to the lake, while ad- ditional cable facilities were also provided south of Oxford Street and on Bloor Street 'West along the new highway. Similarly, in the east- ern section of the rural territory other fire and cable projects were | calls undertaken. Telephone Calls Have Peak 'Hours In an exchange area one can see the tide of telephone calling rise and fall with the daily life of the community. In the average exchange, calls reach their peak in mid-morning, | as the business of the day gathers speed. There's a lull during the lunch hour and then the number of calls rises again toward the mid- dle of the afternoon, when business picks up its tasks again and the housewife remembers a dozen things to be done before supper time. Social activities are usually ar- ranged in early evenings, so the tide runs high again between seven and eight o'clock. As the evening wears on, fewer and fewer calls are made; and by one o'clock in the morning little more than the es- sential services of the community are using the telephone. | Unusual rushes to telephone traf- fic can be caused by a score of reasons--bargain sales, elections, storms, sport events. Some traffic rushes can be anticipated and pre- pared for--long holiday week-ends such as Labour day and, of course the Christmas and New Year season always brings heavy local and long distance traffic. Telephone exchanges are so de- signed that the heavy volume of | during busy hours can be handled efficiently. Wires Act As Nerves Of Telephone System If the central office is the nerve centre of the community's telephone system, then the wires that lead to each telephone instrument might |from the others with paper to pre- vent short eircuits. | The introduction of telephone Radio Used As Adjunct To Telephone Perhaps the most dramatic use of radio as an adjunct to the tele- phone system is in jumping bar- riers caused by the great oceans of the world. In Canada, all calls to the Unit- ed Kingdom travel by land, through the Bell's overseas centre in Montreal, to the Canadian Overseas Telecommunications Cor= poration's powerful directional ra- dio transmitter at Drummondville, Quebec. There the electrical waves are ' amplified some two billion times, changed into radio waves, and hurled across the ocean to Baldock, England. Since these radio waves may be picked up by radio receivers tuned into the proper frequency and in the path of the beam, the mes- sage is "scrambled" by equipment at the Bell overseas centre in Mon- treal. This renders it unintelligible serves the privacy of telephone to radio eavesdroppers and pre- conversation. "Unscrambled" in England, the radio waves are amplified again and transformed back into elec~ trical waves which are passed along by land wires. The call is routed One of Early Bell Telephone Trucks This Bell Telephone truck of 1918 vintage may appear antiquated alongside today's streamlined models, but in its day it was a great boon to expanding Oshawa's teleph a Oshawa telephone workers as they went about the city maintaining and A McLaughlin del, p » y motor vehicle to be purchased by the Bell, which bought its cars and trucks consists of 3,000 vehicles. r d here in Osh first truck in 1909. Today the company's fleet of , the truck was the 53rd by an overseas operator in London to its United Kingdom destina- tion. Calls from England to Canada Generator for Emergencies follow the same procedure but a different route. They leave London by land wire lines to Rugby where the British Post Office transmit- ter beams then to Yamachiche, near Trois Rivieres, Quebec. From the receiving station there, they go by wire to Montreal for "un- scrambling" and routing on to your telephone. # The incoming and outgoing trans-atlantic stations are at dif- ferent locations and their chan- nels are on different frequencies to minimize the possibility of either interferring with the other. As a final safeguard against the chance of the receiver at Yamachiche picking up the beam transmitted from Drummondville, giving the caller the disturbing experience of hearing his own voice echoing back to him, an ingenious control is operated by the voice of the speaker himself. When you being to talk by telephone to someone in England, reception on this side of the ocean is cut off instantly. Transmission takes place in only | one direction at a time though | neither speaker is aware of inter- | acts as ruption for the control quickly as the flick of an eyelid. By overseas radio-telephone, des- pite all the scrambling, amplify ing and unscrambling that goes on at both ends, the human voice travels the distance from Canada 'to England in about one-twentieth of a second!
