TELEPHONE SETS-
302, 303, 304, 305, 306, 307, 309, 329 AND
D-173487 (modified TP-6) TYPES

DESCRIPTION AND USE

1. GENERAL
1.01 This section covers information pertaining to the
302, 303, 304, 305, 306, 307, 309, 329 and the D-173487-type
telephone sets for indoor use.

1.02 This section is reissued to include data on the 329-type
telephone sets and to make various changes, additions
and corrections to bring practice up to date.

1.03 The telephone sets in this section are antisidetone sets
consisting of a handset and a telephone set mounting which, in addition
to a dial or apparatus blank, houses a ringer,
condensers, induction coil and, in certain cases, a vacuum tube. The
only exception is the 329-type set, which does not
have the ringer, condenser or induction coil in the housing. A cord for
connecting the telephone set to the line is also
included. The line is terminated at a connecting block or jack near the
set.

1.04 This section covers mountings with both metal and
thermomastic housings. The latter has a more permanent finish, but is
more fragile than metal housings and should
therefore be handled carefully.

1.05 In general, the sets are installed in accordance with
instructions included in the sections in Division C30 covering the
locating and mounting of hand telephone sets
and the installation of connecting blocks.

Issue 8, October 1955. States number plates may be substituted locally; E1E-3 handset may be used in place of F1A-3 if zoning permits; and shows two-tone colors with the 500-series color codes 50A thru 57A.
