SERVICE There awo two ways to obtain radiotelephone service.One is to rent the mobile equipment from the Bell System or the Radio Common Carrier (rental will include telephone service and repairs), and the other is to buy the mobile equipment directly from manufac.turers and then rent telephone service from either of these systemL Application for equipment rental or telephone service could be made to a local Bell or RCC system company where a licensee or carrier would have most need of the service.If purchased equipment is to be operated on the Bell System, a license will be requited from the Federal Communications Commission (FCC). Purchased equip-ment operating on the RCC system may not require an FCC license, Maintenance of the equipment is provided when it is leased from the Bell or RCC systems.Purchased equipment must be serviced by licensed operatois, as required by FCC regulation | |||
47 CFR 21.207(e), "Transmitter Measurements". | |||
There are several categories which define the priority for obtaining service. Them are described in FCC regulation | |||
47 CFR 21.512, "Priorities for service to subscribers." SYSTEM ASPECTS There are several types of service and equipment that can be obtained. | |||
The service available is dependent on the area. The equipment that can be ordered depends on whether local or nationwide service is desired. In general, the types of service available are: I. Manual service with access to an operator.2. Two-way dial with automatic channel selection and access to an operator (also known as Improved Mobile Telephone Service, IMTS).3. Two-way dial service with access to an operatot.4. Two-way dial service without access to an operator.The most Inclusive service afforded is that of two-way dial with automatic channel selection and access to an operator (IMTS). This service is available on the (152.158) MHz and (454, 459) MHz carriers only. There are at least two varieties of radiotelephone equipment that cart be applied to this service. In one type of radio.telephone operating on the (152. 158) MHz carrier, all eleven channels in the United States are available through the selection of pushbuttons on the telephone. | |||
Additionally, three other pushbuttons, Home. Roam, and Manual, are available. | |||
When a vehicle is in the Home area the Home pushbutton is depressed and the Home area channels will be selecled automatically. | |||
When a vehicle is outside the Home area the channels for the particular area must be selected by depresing the channel pushbuttons, as well as the Roam button.

====e. PREPANNING==== | |||
RadioteJepbone call-in times can be preplhmed in advance of the shipment by wing a booklt issr by the American Telephn and Tekegnph Co. entidted"National Mobile Telephone Service Area Lsting ur a booklet Issued by the Conman Carrier enttAWd"Nationwide Se; "ce Directoy" in conjunctiut with the route rmps to be used with the Whpmint. The area covered by each bw statton can be put cm the route naps, and radiotelephone call-in timim riot to excted 2 hours determined. | |||
When a | When a radiotelephoae call cannot be planned to occur within a 2-hour period, conventional telephone call-in location and time should be deter-mined. fnis can initially be detcmxmired by locating cities, tow"s, or populated commered areas alorl the route. The conventional cal can be preplanned to occur at ani approximate time (planned not to exceed 2 hours)from one of these artas. As experience is gained with particular routes, conventional telephone caLs can be planned with gpeter precision. | ||
The drivers can note specific telephone or areas where telephones are avail.able along the route for future conventional telephone call-in planning, COMMUNICATION | |||
PROCEDURES | |||
A radiotelephone conversation can be overheard by anyone having a radiotel-phone set with the same carrier frequency and channels. | |||
It is therefore necessary to disguise the position of the shipment and the routes to be taken. One method for accomplishing this is the use of a transparent nonfoldable grid overlay on a standard road atlas. This grid can consist of one-half-inch squares with the horizontal axis labeled with letters the vertical axis labeled with numbers. A typical overlay is shown in Figure I and is about 10.5 inches by 14 inches in overall dirmendon. | |||
The road atlas chosen should have a scale of one inch equals 3 miles or lessL The resoution of a one-half-inch square on the overlay would then be Pbout 1.5 miles, 5.32-2 A B C D'E F GH 1 J K L M N 0 P QR S T U 3iiii-i------- | |||

Each map is assigned a number.2. In order to positiin the grid with respcct to the map, reference points are selected on the map. The grid is placed over the map, and distinct intersections or other identifiable landmarks are selected and given grid coor-dinates. These should be placed directly on the map as shown in Figurzt 2 with a relatively fine black marker type pen..3. The driver could use the following procedure to telephone his position: a. Select the map which includes his position.b. Locate his position between two reference points on the map and place the appropriate coordinates over the reference points.

e. PREPANNING
RadioteJepbone call-in times can be preplhmed in advance of the shipment by wing a booklt issr by the American Telephn and Tekegnph Co. entidted"National Mobile Telephone Service Area Lsting ur a booklet Issued by the Conman Carrier enttAWd"Nationwide Se; "ce Directoy" in conjunctiut with the route rmps to be used with the Whpmint. The area covered by each bw statton can be put cm the route naps, and radiotelephone call-in timim riot to excted 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> determined.
When a radiotelephoae call cannot be planned to occur within a 2-hour period, conventional telephone call-in location and time should be deter-mined. fnis can initially be detcmxmired by locating cities, tow"s, or populated commered areas alorl the route. The conventional cal can be preplanned to occur at ani approximate time (planned not to exceed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />)from one of these artas. As experience is gained with particular routes, conventional telephone caLs can be planned with gpeter precision.
The drivers can note specific telephone or areas where telephones are avail.able along the route for future conventional telephone call-in planning, COMMUNICATION
PROCEDURES
A radiotelephone conversation can be overheard by anyone having a radiotel-phone set with the same carrier frequency and channels.
It is therefore necessary to disguise the position of the shipment and the routes to be taken. One method for accomplishing this is the use of a transparent nonfoldable grid overlay on a standard road atlas. This grid can consist of one-half-inch squares with the horizontal axis labeled with letters the vertical axis labeled with numbers. A typical overlay is shown in Figure I and is about 10.5 inches by 14 inches in overall dirmendon.
The road atlas chosen should have a scale of one inch equals 3 miles or lessL The resoution of a one-half-inch square on the overlay would then be Pbout 1.5 miles, 5.32-2 A B C D'E F GH 1 J K L M N 0 P QR S T U 3iiii-i-------

Overay with 1/2-inch grid (not to scale) :a1C)5.32-3 With a scale of one inch equals 3 miles, it may be necessary to use several road maps to cover a shipment.A typical procedure that could be followed under these conditions is ai follows: I. Each map is assigned a number.2. In order to positiin the grid with respcct to the map, reference points are selected on the map. The grid is placed over the map, and distinct intersections or other identifiable landmarks are selected and given grid coor-dinates. These should be placed directly on the map as shown in Figurzt 2 with a relatively fine black marker type pen..3. The driver could use the following procedure to telephone his position: a. Select the map which includes his position.b. Locate his position between two reference points on the map and place the appropriate coordinates over the reference points. Telephone the position as map number, reference points, and actual coordinates.
4. Duplicate sets of maps should be made by the licensee or his agent prior to the shipment;
copies should be given only to the drivers and escorts (when they are used) and the individuals'responsible for maintaining telephone conununication with the shipment.Another method that can be used to disguise the position of the shipment is known as the "check point" system. This approach, applicable to preplanned routes, uses landmarks as check points. The landmaiks are typically all towns, cities, villages, state lines, and major highway intersections along the preplanned route. The landmarks are identified by a symbol (number or.alphabetical character)
on a single strip map carried along with the shipment.
The driver, in reporting hi3 position, relates only the symbol applicable to his position, or "x" number of miles from a landmark.Mileages between landmarks and those locations where commercial telephones are available on the strip maps may also be included.
Personnel controlling the ship-ment should have a corresponding strip map and plot the progress and locations of the shipment.A third method of disguising the movement of a shipment is through the use of a telephone voice scrambler.
This device, when placed in front of a telephone, will "scramble" the message over the com-munication link and will produce unintelligible sounds at the other end of the circuit unless a companion device which is matched to the sending device is also available in front of the telephone at the other end. Telephone voice scramblers are therefore available in coded pairs and can be made available in matched sets of more than two units to handle conference calls or calls from a vehicle to different locations.
C. REGULATORY
POSITION 1. SYSTEMS ASPE.'h The system that provides the mot coverage alng the route of the shipment shoutd be selecte4.
After a system has been selected (i-e., Bel or RCC) the radiotelephone selected should have all ar-i-able channels for the carrier dciton. Further, the telephone shall be dialable and should provide for uLpIex operation.
2. PRP.ELANNMNG
The Ikcensee should prelan the shipment route if he is going to make the Whipomnt;
otherwise, .v should obtain a preplanned route from the carrier. Routes should be preplaned to u3e as much radiatiekbone coverage as possible.
The requiren=t that transt utmes be minimiwed (pa graph 73.30(b))
should be u rbsewd.however, making radiotelephon cals is the mor desir-able feature, and transit times could be soanewhat increased to accommodate good radiotekephone cover-age. Since all radiotelephone station may not accept calls from a number whbch is not in the koa diractery.
calls to each radiotelkphom afea xue-ted should be mrWe to assure that the operators will accept outside calls. Where radloteiephotv, coverage is not available without evtensive rerouting.,
Irlephone calls should be preplanned every two hours wben available along the routz.The licensce(s)
mx agent(s) responsible for conumuni-cations liaison with the shipment should be predeco-hated before a shipmeat is made. A continuoudy manned telephone with an unlisted number should be provided at the licenee's of agent's facifily.
Thts telephone should not be used for any other calls while a shipment is in progres.Appropriate lcal law enfor-ement authorities (LLEA) such as the Head of the State Police, the State Safety Director.
or the local State police barracks.should be contacted in advance of a shipment to assure that recovery procedures will be followed and that adequate response forces will be available along the mute. Once initial contact has been made it is nnA necessary to reestablish contact for cubsequent ship.rrents through the same jurisdiction except that pro-cedures should be reaffirmed at least arnually.
The telephone number of the LLEA along the preplanned route of the shipment who will be called in cm of an emcrgency or failure of the transport vehkkl to call in should be given to the vehicle crew and the person(s)responsible for naintAining comiunncatioms with the vehicle crew.
