cord, but do not connect the mounting cord at this
time. The use of a 625-type connecting block
(Fig.
2) is recommended. For information on other
modular connecting blocks or adapters, refer to
Section 503-100-100.
Warning: Any magnetic stripe card
may
have its encoding destroyed if
the card is carried or stored near a
ma,rnet or magnetized object.
3,02 Connect the TRIMLINE® handset to the
5000AMtelephone set base using the handset
cord and adapter. (A 616P jack is provided on
the front of the base.)
3,03 Insure that there is an available 110-volt
3-wire AC receptacle, not controlled by a
switch, within reach of the 6-foot power cord.
A 3-wire outlet is required for safety
and proper operation of the set. Third
conductor must be grounded. If third
wire is not provided and grounded,
the resistance of the set to
t!lectrostatic damage is lowered
and the probability of failure is
greatly increased.
3!04 To install 138-type faceplate, proceed as
follows:
(1) Remove disposable faceplate by lifting at
the midpoints of the left and right edges.
When faceplate is bowed slightly, the locking
tabs at top and bottom will release.
Note:
If
auxiliary manual entry pad is to
be installed, do not installl faceplate at this
time.
(2) Install new faceplate by inserting bottom
tab into housing and slightly bowing the
faceplate enough to insert upper tabs into slots
of housing.
TRANSMISSION MEASUREMENTS(INSERTION LOSS)
3.05 The signal output level of the TOUCH-TONE
frequencies transmitted by the Transaction
I set must be adjusted to match the loop being
used. Make a loop insertion loss measurement
using a 23D Transmission Measuring Set, or the
equivalent, and a 900 ohm termination. Dial the
milliwatt supply (1000 Hz) of the serving central
office; read and record the loss of the loop.
3.06
It
is recommended that at this time the set
should be opened (3.07) and all option plugs
on main printed wiring board (PWB) checked to
insure that they are in their "when shipped"
positions as shown by Tables C and D or Fig. 4.
Checkwiring terminations and if any looseconnections
are found, reterminate per Fig. 9.

for the actual measured loss (AML) of the
l9op (3.05) as follows:
I
I (1) Place the option plugs in their proper positions
, for the measured loss. As shown in Table C
: and Fig. 4.
: (2) If the actual measured loss of the loop is
' 3.9 dB, or less, resistors R2 and R3 should
be placed in the circuit. This is done by moving
the orange (0) and slate (S) leads from pins T2
and R2 to pins O and S, respectively. See
Table C and Fig. 9.
Note: Early production sets do not have
the pin connector arrangement but have clip
type terminals for placing resistors R2 and
R3 in the circuit. The green (G) and red
(R) leads from the 623E4 jack are connected
to terminals T and R, respectively, and the
(0) and (S) leads are connected across the
Transaction I 3-10
ISS 3, SECTION 502-323-400
resistors by clip-type terminals. If the AML
of the loop is 3.9 dB, or less, proceed as
follows:
(a) Remove (G) lead from terminal T on
control board. Remove either end of (0)
lead from clip-type terminal at R3 and connect
to terminal T. Connect (G) lead which was
removed from T to now vacant R3 clip-type
terminal.
(b) Remove (R) lead from terminal R on
control board. Remove either end of (S)
lead from clip-type terminal at R2 and connect
to terminal R. Connect (R) lead which was
removed from R to now vacant R2 clip-type
terminal.
(3) If loss of loop exceeds 12:dB the quality of
the service may be impaired. Defer, according
to local procedures, until an acceptable loop is
made available.
3.09 Connect the set to the telephone line by
inserting the mounting cord into the connecting
block.
3.1 0 Remove the gum-backed "OPTIONS" sticker
which is packed with the base and attach
it to the bottom of the base near the front. If
the service order does not call for the implementation
of any options (Dial Pulse, Lockout, or disconnection
of the ringer) at this time, reassemble set and
proceed to 3.12.
Note: If the order calls for making dial of
hand telephone set inoperable, do not disable
dial until all testing is completed.
OPTIONS
The service order must specify that
each option is, or is not, required. If
the service order does not so specify,
the sales representative should be
contacted, or refer to supervisor
for clarification of requirements.

or TOUCH-TONE telephone set (as applicabl e)
according to local procedures.
REMOTE TEST PROCEDURE
In
the following test there must not
be over
a
IO-seco nd dela y between
steps or the test line will interpret
this
as an
error.
Note:
If an interrupted tone (1/2 second on,
1/2 second om. lasting about 5 second s, is
hea rd at any time, an error is indicated. The
IA Transaction Telephone Test Line Station
(TTTLS ) will disconnect at the end of the
interrupted tone. To retest, it will be necessary
to redial the test line (3.15) through (3.19).
3.15
Go off-hook, first instruction lamp is lighted
and dial tone is heard. Manually dial the
number of the Transactio Telephone Test Line
Station (TTTLS), using the TRIMLINE handset.
3.16
When the call is completed to the TTTLS,
it wiII respond with a 3-second answer tone
which will be heard on the TRIMLINE handset.
After the answer tone has terminated, the test
card should be passed through the reader two (2)
times. The instruction lamps should sequence-the
second instruction lamp should light after the card
is passed through the first time, and when the
card has been passed through the second time,
the third lamp will bP lighted.
