WIRE MAINTENANCE SECTION
The following installation and maintenance duties were performed by
this Section:
1. For the projected move of NSA from Arlington Hall to Fort
Meade; the C&P Telephone Co. has installed 113A Carrier Units at OCI,
1503 "L" Building and at 1717 "H" Street. With this Carrier system
all of the circuits go directly from each area to NSA and do not go
through the "L" Building Signal Center Switchboard, as did the OCI
circuits previously.
Also for this move two each complete "on line" 131B2 tables and
Model 19's had been requisitioned and are now wired for "on line"
operation. One of the complete units has been sent to Fort Meade
and the other will be installed at the OCI Commmcenter. These units
are to be used between the
An "on line" receive only circuit will also be installed at OCI as
soon as the necessary equipment is received. The OCI circuits will
be cut over approximately October 12th.
2. Two Tiny Tot units were wired in our shop and were picked
up by= personnel for their school. One more Tiny Tot that was
returned from NSA is now being checked out and this will also go to

3. We are still spending all available time on the splitting of
the APSAM-7 kits. This is a slow business and at this time approximately
one and a half kits have been completed.
1+. Four of the men from this Section have been attending school
E The Basic Teletype course started September 3rd, and will end
on September 27th. The Sig Tot and Tiny Tot Course will commence on
September 30th and ends October 25th.
5. The two Kleinschmidt teletype equipments Model 154+, have been
PTI-'.D to the Warehouse. No further tests or evaluations were made on
this equipment.
6. Sometime in the very near future, the Wire Maintenance Section
will be moving to Wing "I", Curie Hall. Floor plans have been submitted
showing the projected layout of our furniture, equipment, the needed
partitions, and AC outlets. In preparation for this move we have been
attempting to dispose of all our P.T.I. equipment and any other equipment
we have that has to be installed.

This system utilized the "tape loop"
principle and was attempted to see if three full duplex circuits
would be possible in the same amount of space at the

Division personnel witnessed the trl run and no comments were made.
This equipment has now been converted back to straight Tiny Tot, and
the two units were sent

8. One OTP machine maze from the Signal Center was brought into
our shop to be modified. The bypass and reject relays which were "Y"
type relays, have been replaced with IBM relays. This unit is used
as a spare for two OTP machines.
25X1A2d1 9. has a new full duplex circuit coming into operation
around the first of October. The equipment needed for this circuit
is two "on line" Sig Tots. No additional equipment was ordered as one
of these units is already wire up for "on line" operation, and at the
present time is used on their FOB4 circuit. At the time this full duplex
circuit is activated the FCB4 circuit will close down, and that on
line unit will be available. The other "on line" unit needed was
accomplished by converting one of their "OFF LM" units to "on line".
10. We received a Tiny Tot unit from NSA that they had had on
loan, and this unit will be checked out, standardized, and sent to
25X1 A6a One Model 19 keyboard was modified for Tiny Tot operation for
E and has been sent back to them.
