Facilities

Both local and long-distance directly-dialled calls can be paid for as they are being made.
The coin-box takes sixpences and shillings, which are collected in a locked cash compartment. Only the renter has the key.
The arrangement is simple to use, and full instructions are given on the front of the coin-box. A caller dials first and pays when the call is answered and a pay-tone is heard. The tone is heard again when the time paid for has been used up. To prolong the call, more money can be inserted in the coin-box at any time during the call or as soon as pay tone is heard again.
Directly-dialled calls are charged in 6d units. The time bought for a unit varies with the distance, and extra time is allowed on all calls during the cheap rate periods. Full details of call charges and the times allowed for different distances are provided in a dialling instructions booklet.
The renter gets a rebate on the call units. On the telephone account, a charge of only 4d is made for each unit for which 6d was collected by the coin-box.
Trunk calls which cannot be dialled directly are obtained by dialling the operator who will say when and how much money should be put in the coin-box. For this type of call, time is bought in 3-minute periods and the renter gets the coin-box fee (is a call during the standard rate period and 6d at other times).
Emergency calls to 999 can be made right away, without inserting coins.
Incoming calls are indicated by a bell inside the coin-box. A belt is also provided near the socket so that calls are not missed if the coin-box is unplugged.

GENERAL INFORMATION

The coin-box is normally provided as a free-standing unit for use on a shelf or counter, but it can be fixed by means of screws in the base to a table or trolley if required.
The handset and its rest are lacquer red, and the body is Post-Office red. The coin-box is 19.75in high, 8.5in wide, 6.5in deep, and weighs 34 lb.
The cord between coin-box and plug is 25� long; the socket is fitted where convenient to the renter, except that it
must be indoors. When the coin-box is temporarily positioned outside the plug can be passed through a hole to reach the socket. If the coin-box is in the open, say on a garage forecourt, it should be well protected from the weather.
Additional sockets can be provided by using the equipment in a Plan 4 arrangement. The coin-box can also be used as the main instrument in the Plan 1A described in DLA 100, although certain limitations are imposed on the extensions.
