Issue 1, August 1976
WITH 220- OR 2220-TYPE
1. GENERAL
1.01 This section contains identification, installation,
connection, and maintenance information for
the Transaction II telephone set which consists of
a51OOAM base, faceplate and a220- or 2220-type
hand telephone set. For detailed information on
components, refer to CD- and SD-69926-01.
1.02 Whenever this section is reissued, the reason
for reissue will be listed in this paragraph.
1.03 For use behind akey system, Aand Al
leads are provided by the black (BK) and
yellow (Y) leads, respectively, in the mounting cord.
If common audible ringing is to be provided, a
separate ringer is required.
1.04 For additional information on the Transaction
telephone system, refer to Technical Reference,
PUB 41804, titled “Switched Network Transaction
Telephone System Interfacing With Audio Response
Units.”
2. IDENTIFICATION
2.o1 The 51OOAMTransaction telephone set base,
equipped with a220- or 2220-type hand
tele~hone set (Fig. 1) provides the standard features
of a
set. single line rotary or TOUCH-TONE” telephone
Note: If the customer elects to have the
dial of the hand telephone set made inoperable
(as covered by 3.33) then it can only provide
incoming service and card dialer service.
It can also automatically dial and electronically
transmit information read from amagnetic stripe
on acredit card, or keyed on a15-button manual
entry pad (Fig. 1), to adata center for immediate
credit authorization, check verification, or inventory
control. In addition, it is possible for atransaction
to be accomplished in ahands-free mode.

2.04 The 51OOAM Transaction II telephone set
base is available in Ivory (-50) only. These
bases will be shipped with adisposable protective
faceplate, so it is necessary to order the proper

Note; The 51OOAM telephone set base is avail-
able in Ivory only and the hand telephone set
should also be Ivory. The faceplate must be
ordered separately.
3.02 Connect the TRIMLINE@ handset to the
51OOAMtelephone 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.
A3-wire outlet is required for safety
K
andproper operationof the set. Third
!/ conductor must be grounded. If third
wire is not provided and grounded,
the resistance of the set to
electrostatic damage is 10wered
and the probability of failure is
greatly increased.
3.o4 To intall 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.
(2) Install new faceplate by inserting bottom
tab into housing and slightly bowing the
faceplate enough to insert upper tabs into slots
of housing.
Note: If auxiliary manual entry pad is to
be installed, do not install faceplate at this
time.
TRANSMISSION MEASUREMENTS (INSERTION LOSS)
3.05 The signal output level of the TOUCH-TONE
frequencies transmitted by the Transaction
11 set must be adjusted to match the loop being
used. Make aloop insertion loss measurement
using a23D Transmission Measuring Set, or the
equivalent, and a900 ohm termination. Dial the
milliwatt supply (1000 Hz) of the serving central
office, read and record the loss of the loop.
Page 4

3.06 It is recommended that at this time the set
should be opened up (3.07) and all option
plugs on main printed wiring board (PWB) and
control board checked to insure that they are in
their “when shipped” positions as shown by Tables
Cand Dor Fig. 4and 5. Check wiring terminations
and if any loose connections are found, reterminate
per Fig. 11.

To open set in order to access option plugs
and/or terminals proceed as follows:
Disconnect power plug from AC outlet, if
connected.
Invert set and loosen the two captive screws
holding the upper housing and chassis (Fig.
Lay the upper housing and chassis to the
right, as shown by Fig. 6, without disconnecting
cables.
To reassemble, reverse procedure.
Set the TOUCH-TONE signal output level
for the actual measured loss of the loop
as follows:
Place the options on their proper positions.
See Fig. 4and Table C.
If the loss of the loop is 3.9 dB, or less,
resistors R2 and R3 on the control board
should be placed in the circuit. This is done
by moving the option pins from B-C to A-B as
shown by Fig. 5.

the service may be impaired. Defer, according
to local procedures, until an acceptable loop is
made available.

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
3.11 If the service order specifies that the Dial
Pulse and/or Lockout options be activated,
or that ringer be disconnected, access the main
PWB (3.07) and proceed as follows:
(a) If both Dial Pulse and Lockout options are
called for:

Place upper housing and chassis back on
set and reconnect AC power cord.
Go off-hook and, using manual entry pad,
dial any test number and verify that the
call is completed. This tests the dial pulse
feature.
(4) Disconnect power cord, lay upper housing
and chassis aside, and move Lockout
option plug to lockout position per Table D.
(5) Reassemble set and reconnect AC power
cord.
(6) Test lockout by going off-hook and

PRELIMINARY TEST PROCEDURE
3.13 Go off-hook by lifting handset; first and
fourth instruction lamps will light. Replace
the handset; both lamps will extinguish. Press
the ON button; both lamps will light again. Run
test card B(card is packed with the 51OOAM base)
through the card reader from right to left. Card
must be held with the magnetic stripe down and
to the front and must be moved through the slot
smoothly and without hesitation. First instruction
lamp should go out and second instruction lamp
should light. Correct operation of these lamps
indicates that the test card is properly coded and
the card reader is good. If the card is not read
correctly the first lamp will blink and the card
reading procedure should be repeated. Press the
OFF button; both lamps will extinguish.
INSTALLATION TEST
1SS 1, SECTION 502-323-401
PROCEDURES
3.14 Using the TRIMLINE handset, perform the
normal tests, including ringback, for arotary
or TOUCH-TONE telephone set (as applicable)
according to local procedures.
3.15 Depress ON button (listen to dial tone), and
check operation of call progress tone sounder
volume control (Fig. 1). Adjust volume control to
acceptable level and depress OFF button.
REMOTE TEST PROCEDURE
!!lr
In the following tests there must not
be over a10-second delay between
!steps or the test line will interpret
this as an error.
3.16
Note: If an interrupted (1/2 second on, 1/2
second off), lasting about 5seconds, is heard
at any time, an error is indicated. The 1A
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 (3.16) through (3.22).
Go off-hook by lifting the handset, first
and fourth instruction iamps are lighted and
dial tone is heard. (The fourth instruction lamp
will remain lighted as long as the set is off-hook.)
Manually dial the number of the 1A Transaction
Telephone Test Line Station (TTTLS) using the
TRIMLINE handset.
3.17 When the call is completed to the TTTLS,
it will respond with a3-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 be lighted.
3.18 Key in digits by depressing buttons on the
manual entry pad, in sequence, 1through
9, ●,O, /, and END. The third instruction lamp
will now be extinguished. While you are doing
this, the set will transmit the buffered data as
TOUCH-TONE pulses. The digits keyed in will
have appeared on the visual display as they are
