1. GENERAL DESCRIPTION
1.01 This section has been generally revised
to include recent engineering changes and
to add late 35 type equipment.
1.02 The 35 Automatic Send-Receive (ASR)
Set is basically an electro-mechanical
device capable, when properly adapted, of send-
ing and receiving messages over telephone net-
works, telegraph lines, or radio channels. The
set accommodates message transmission at 100
words a minute. All messages (received or
transmitted) may be typed on either page size
copy paper or continuous business forms and
they may be punched in paper tape with or with-
out the message typed on the tape, depending on
the equipment combinations and options used.
1.03 The component complement of an ASR
Set may vary from one installation to
another, depending upon the installation require-
ments. In general, an ASR Set will consist of a
page printer, keyboard with reperforator, motor
unit, transmitter distributor and its base as-
sembly, electrical service unit, and cabinet. A
call control unit is included with sets that oper-
ate with tone modulation over telephone networks
(switched network service).
1.04 A data set, required for operation of the
ASR Set over the telephone network, is
mounted on the apparatus rack in the pedestal
of the cabinet of sets so equipped. It is not sup-
plied as a part of the ASR Set.

CABINET (Figure 1)
2.01 The cabinet is designed to house the com-
ponents of the 35 ASR Set. It is a floor
standing enclosure made up of two main parts:
the pedestal, or lower cabinet, and the cover, or
upper cabinet.
(a) The pedestal is of sheet metal construc-
tion, and rests on two feet which extend
forward to support the weight of the set.
Cabinets used with sets that print data on
continuous business forms should be equipped
also with rearward extending feet to prevent
tilting of the enclosure due to the weight of
the form container on the back of the cabinet.
An equipment supporting pan is spot welded
to the top of the pedestal. The pan contains
