identical for both the QSD400Al and
QSD2400Al.
2.06 The electrical components in the coin
telephone set are plug-ended for ease
of
substitution. The components interconnect
through jacks on the apparatus module.
2.07 The NE-425QE1 network and TBl terminal
strip, which permits the strapping
of
some
of
the optional features, are riveted
to
the
apparatus module. The NE-C4A ringer is mounted
at the
top
of
the apparatus module. A large screw
located between the jacks retains the apparatus
module in the housing assembly.
2.08 The CENTURION coin telephone set
is
equipped w
it
h mechanical and electronic
initial rate coin totalizers which inhibit dialing
from the coin telephone until a preselected amount
in coi
ns
has been deposited.
2.09 When shipped from the factory the
CENTURION 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.
2.10
Th
e electrical Variable Initial Rate (VIR)
totalizer
on
the Printed Circuit
Bo
ard (PCB)
assembly in the coin telephone set can be modified
to
change
the
initial
rate
from 5-cents through
40-cents in increments
of
5-cents.
2.1
1 The Free Access
to
Selected Numbers
(F
ASN) fea
tur
e permits coinless calling
to
special preselected numbers. The
CO
must
be
equipped for FASN and the line must have a
loop-start line circuit.
2.12 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.
2.13 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.
2.14 The transmission qualities
of
the
CENTURION coin telephone sets are
similar
to
those
of
the
NE-500
type
telephone set.
2.15
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 less
than
4.4 vo
lt
s.
(b) The current in
the
ring side
of
the line
should
not
be less
than
23.0 milliamperes
with the hopper trigger switch in
the
normal
position (i.e.,
not
tripped).

3. CIRCUIT DESCRIPTION
Coin Signaling
3.01 Coins inserted in the · single slot and
accepted by the chute are sorted into the
appropriate channel before passing through the
coin switch module.
As
the coin passes through the
coin switch module, a switch is activated which in
tum
energizes the solid-state tone generator. The
generator sends bursts
of
tone appropriate
to
the
coin deposited
to
permit operator recognition. The
signal~
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).
Mechanical Totalizer
3.02 The mechanical totalizer detects the total
number
of
5-cent coins deposited for
10-cent initial rate calls.
3.03 The first 5-cent coin,when passing through
the coin switch module, operates the
totalizer and drops in the coin hopper,tripping the
coin trigger. When tqe second 5-cent coin
is
deposited the mechanical totalizer permits dialing
from the coin telephone set. The operated hopper
trigger switch provides ground on
the
CO line
to
collect/return the deposited coins and
to
request
service on ground startline circuits.
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 ca
ll
to
proceed.
The mechanical totalizer
is
not
operated by the
deposit
of
these coins.
Page4
Electronic Totalizer (VIR)
3.05 The electronic totalizer
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
signals 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 F
ASN
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.
F
ASN
Operation
3.06
When
the coin telephone set is used with a
CO
which
is
equipp.ed
to
provide F
ASN
service the user receives dial tone by lifting the
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
th
e 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 slot in the coin guide
are directed
to
the coin chute and rejected
to
the
coin return assembly
or
held up. The coin return
button,
when pressed, has a positive clearing
action, which releases
the
slugs, washers, etc.,
into
the
coin
return
assembly.
