The GPO/PO/BT had many publications that make excellent
reference sources. The A range (A series also included forms etc) is listed
below - but this is not the complete list - why not advise us of the missing
ones?
Instruction leaflets were usually a white A5 card with the instructions
printed on them. If a lot of information was needed (e.g. switchboard
instructions) then a small booklet was produced.A list of the A range is
partially available in database

ISSUING PROCEDURE
Conversion of an exchange area to automatic working If pre-transfer visits are
made by the traffic staff, the instruction cards are distributed by visiting
officers. If pre-transfer visits are not made by the traffic staff,' instruction
cards should be distributed by the engineering officer making the dial-speed
test. Dialling code cards and booklets will be dispatched by the TM (Traffic
Divn).
Conversion of subscribers' installations from one exchange system to another
On small area-correction transfers if a change of system is involved, the
installation officer should normally provide the instruction cards for
installations specified in par 2. If a large group of subscribers is concerned,
the supply may be arranged by the TM (Traffic Divn).
New Installations on existing exchanges If the apparatus is listed in par 2,
the -Instruction card or booklet should be provided by the installation staff,
who should also supply a dialling code card or booklet as appropriate.
LOCATION OF CARDS OR BOOKLETS
Subscribers should be advised to keep the card or booklet close to the point of
use. At certain PBXs a hook may be provided for the purpose (see E3001).
LOCAL STOCKS
Installation controls and detached fitting centres should hold small stocks of
the instruction and dialling code cards and booklets detailed in Table1. Except
for cards referring to obsolescent apparatus known to exist in the Area and
apparatus which is not covered by current cards or booklets, stocks of
obsolescent cards and booklets should be made waste.
BLIND SUBSCRIBERS IN AUTOMATIC AREAS
These subscribers will usually be able to memorise the dialling coded used, but
if they appear to be in any difficulty a Braille dialling code list is required
the TM (Traffic Divn) should be advised.
