GENERAL
1.01 This section describes the QSD300A and
QSD2300A prepay, single coin slot, panel
coin telephone sets. Dismantling and assembling
information
is
given to facilitate installation
of
the
coin telephone sets. Station wiring and option
connections are also provided.
2. DESCRIPTION
2.01 The QSD300A and QSD2300A coin
telephone sets are single -slot, prepay type
panel coin tel.ephones. The QSD300A, equipped
with a rotary dial, and QSD2300A, equipped with
a DIGITONE* dial, are shown in Fig.
1.
The sets
can be converted from rotary dial
to
DIGITONE
dial by interchanging the door assembly.
2.02
The
panel coin telephone set components
are contained within a sheet steel housing
which is fabricated by a combination
of
welding
and bolt fasteners for maximum security.

of
Northern Electric.
Page2
2.03 The front
of
the set features a brushed
chrome center panel which contains the
coin slot, coin release lever, handset hook, dial,
instruction and number card windows, coin return,
and cash compartment door. Decorator panels
of
brushed stainless steel
or
. panels with a painted
finish are inserted on each side
of
the center panel.
2.04 The QSD300A and QSD2300A coin
telephone sets are equipped with
mechanical and electronic initial rate totalizers
which inhibit dialing from the coin telephone until
a preselected amount in coins has been deposited.
2.05 When shipped froin the factory, the
QSD300A and QSD2300A sets are arranged
to operate on the mechanical totalizer at a 10-cent
initial rate. With this arrangement the set may be
used on either ground-start
or
loop-start central
office (CO) lines.
2.06 The electronic variable initial rate (VIR)
totalizer on the printed circuit board (PCB)
assembly in the coin telephone set can be modified
to
change the initial rate from 5-cents
to
40-cents
inclusive in increments
of
5-cents.
2.07 The free access to selected numbers (FASN)
feature permits coinless calling to special ·
preselected numbers. The
CO
must be equipped for
FASN and the line must have a loop-start line
circuit.
2.08 Ground isolation (GI) disconnects the
grounding circuit from the transmission
path to minimize line induced noise during voice
transmission. This feature requires that the
CO
line
is equipped with a loop-start line circuit.
2.09 The coin identification signals are
transmitted to the operator by a solid state
tone generator when the required coins are
deposited in the coin telephone set.
'
2.10 The transmission qualities
of
the QSD300A
and QSD2300A coin telephone sets are
similar to those
of
the NE-500 type telephone set.
2.11 The maximum loop resistance for
satisfactory operation
of
the set
is
determined by such parameters as minimum CO
battery voltage, feeding-bridge resistance, ringing
cut-off current, etc. To ensure reliable operation
it
is recommended that the following conditions be
met.
(a) With the handset off-hook the de voltage
at
the ring and tip terminals
of
the set must
not
be l
ess
than 4.4 volts.
(b) The current in the ring side
of
the line
shou
ld
not
be less than 23.0 milliamperes
with the hopper trigger switch in the normal
position (i.e.,
not
tripped).

coin switch module.
As
the coin passes through the
coin switch module, a switch is activated which
in
turn energizes the solid-state tone generator. The
generator sends bursts
of
tone appropriate
to
the
coin deposited
to
permit operatorrecognition. The
signals are
not
heard in the receiver
of
the coin
telephone set. The number
of
tone bursts for each
coin deposited are:
• one burst for a 5-cent coin
• two bursts for a 10-cent coin
•
five
bursts for a 25-cent coin (transmitted
at twice the.rate
of
the 5-cent and
10
-cent
coin tone bursts).
may limit the loop resistance to less than
23-l/
4
1365 ohms.
For
higher loop resistance a long
line circuit should be used.
2.12 The coin telephone set weighs
approximately
55
pounds (25 kilograms).
2.13 The dimensions
of
the QSD300A and
QSD2300A coin telephone sets are shown
in Fig. 2.

Mechanical Totalizer
3.
02
The
mechanical totalizer detects the total
number
of
5-cent coins deposited for
I0-cent initial rate calls.
3.03
The
first 5-c
ent
coin is trapped in the switch
module.
The
5-cent coin in the trapped
position holds a switch operated. This switch
provides a connection to ground which
is
necessary
for central offices having ground
start
line circuits.
The
second 5-cent coin
is
deflected by the first
5-cent coin (which is trapped) and passes
on
through the switch module i
nto
the coin relay
hopper.
On
entering the hopper,
it
trips the hopper
trigger switch.
The
operated hopper trigger switch
removes a
short
circuit from the dial and the user
can now dial.
3.04 A deposited 10-cent coin
or
25-cent coin is
segregated by the coin chute and passes
through the coin switch module.
The
tone
generator monitors the switches
on
the switch
module and generates the appropriate coin signals.
The
coin then drops into the coin hopper, tripping
the
hopper
trigger which allows the call to proceed.
The
mechanical totalizer is
not
operated by the
deposit
of
these coins.
ElectronicTotalizer (VIR)
3.05
The
electronic
tota
lizer
is
used to inhibit
dialing
(or
continuity
to
ground for FASN
operation) in the same manner as
the
mechanical
totalizer.
The
electronic totalizer receives its
input
signa
ls
from the same switches
on
the switch
module which provide inputs
to
the coin signal
tone generator.
The
electronic totalizer can be
strapped
(on
the PCB assembly) so
that
it enables
dialing
(or
continuity to ground for FASN
operation) when the total value
of
the coins
deposited equals
or
exceeds
the
preset initial rate.
The initial rate
may
be preset by appropriate
strapped connections
on
the PCB assembly.
FASN Operation
3.06 When the coin telephone
set
is used with a
CO which
is
equipped
to
psovide FASN
service the user receives dial tone
by
lifting the
Page 4
handset and may complete a call to any free access
number without depositing coins.
3.07 When a non-FASN call
is
made, ground
identification
is
detected· by the
CO
when
the initial rate
is
deposited.
GI Feature
3.08
The
GI feature provides a means
of
disconnecting the station ground from the
transmission network whenever line current is
flowing. This feature achieves a substantial
reduction in transmission circuit noise caused by
induced voltages on the line.
3.09 GI
is
activated by current
on
the ring side
of
the line. When this feature
is
used, ground
tests
or
coin collect/return functions, which
require an electrical continuity to ground, must be
made
on
the tip side
of
the line only.
Coin Rejection
3.10 Slugs, washers, tokens
or
foreign coins
inserted through the coin entry slot are
directed
to
the loin chute and rejected to the coin
return assembly
or
held up.
The
coin-return lever
when operated, has a positive clearing action,
which releases the slugs, washers, etc., into the coin
return assembly.

The
following factors should be considered
when
choosing a location
for
the
installation
of
the
panel coin telephone set:
• Accessible for public usage
• Adequate light
• Privacy
• Minimum noise or
vi
bra
ti
on
• Absence
of
grease, smoke or dust
• Clear
of
moving machinery, piled
merchandise, narrow aisles or stairways
• Check local installation practices before
mounting the coin telephone set on
surfaces
that
would
be
expensive to repair
if the set is removed.
• Telephone and wiring must be located at
least 6 inches from neon light fixtures,
transformers
or
other equipment likely
to
cause inductive effects.
• The QSD300A and QSD2300A coin
telephone sets must be mounted on a
vertical surface. A tilt greater than
1.5
degrees
in
any direction can cause chute
malfunction.
MOUNTING INSTRUCTIONS
5.03 The QSD300A and QSD2300A coin
telephone sets have mounting screw holes
identical to those provided on the NE-233 type
coin collectors. Fig. 5 shows the arrangement
of
the mounting screw holes.
