WARNINGS
DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT.
Be careful when working on the 115-volt ac line connections. SERIOUS INJURY or DEATH may result from
contact with these connections.
Adequate ventilation should be provided while using trichlorotrifluoroethane. Prolonged breathing of vapor
should be avoided. The solvent should not be used near heat or open flame; the products of decomposition are toxic
and irritating. Since trichlorotrifluoroethane dissolves natural oils, prolonged contact with skin should be avoided.
When necessary, use gloves which the solvent cannot penetrate. If the solvent is taken internally, consult a physician immediately.
Buffer, Data TD-1065 weighs 39 pounds. Use two men to carry or lift this unit to prevent injury. Due to lack of
carrying handles, personnel must ensure a positive grip on the item before lifting to avoid dropping the unit.
CAUTIONS
To prevent damage to circuit card assemblies do not make resistance measurements on circuit card assemblies
or on the data buffer unit while circuit card assemblies are installed.
Handle circuit card assemblies by edges only to prevent component damage by static discharges. When installing replacement card, carefully remove conductive film from connector pins.
Place POWER switch to OFF before removing or inserting circuit card assemblies.
Do not adjust variable controls on any circuit card assembly.

1-7. Purpose and Use
The purpose of the data buffer is to provide a means for
transmitting high speed data and voice traffic over existing
Army Tactical Area Communications System (ATACS)
equipment. The data buffer provides a 6 or 12-channel
digital transmission capability and is used with Multiplexers such as the TD-660A/G and TD-660B/G. Multiplexer TD-660/G cannot be used with the data buffer.
NOTE
Data buffer serial numbers 001 through 018
(first article units) have only 12-channel capability as initially delivered. These units will
be modified for 6/12-channel capability when
the ECP is incorporated for production units.

MAINTENANCE ALLOCATION
Section I. INTRODUCTION
D-1. General
This appendix provides a summary of the maintenance operations for Buffer, Data TD-1065/G, It authorizes categories of maintenance for specific maintenance functions on repairable items and components
and the tools and equipment required to perform each
function. This appendix may be used as an aid in planning maintenance operations.
D-2. Maintenance Function
Maintenance functions will be limited to and defined
as follows:
a. Inspect. To determine the serviceability of an
item by comparing its physical, mechanical, and/or
electrical characteristics with established standards
through examination.
b. Test. To verify serviceability and to detect incipient failure by measuring the mechanical or electrical
characteristics of an item and comparing those characteristics with prescribed standards.
c. Service. Operations required periodically to keep
an item in proper operating condition, i.e., to clean (decontaminate), to preserve, to drain, to paint, or to replenish fuel, lubricants, hydraulic fluids, or
compressed air supplies.
d. Adjust. To maintain, within prescribed limits, by
bringing into proper or exact position, or by setting
the operating characteristics to the specified parameters.
e. Align, To adjust specified variable elements of an
item to bring about optimum or desired performance.
f. Calibrate. To determine and cause corrections to
be made or to be adjusted on instruments or test measuring and diagnostic equipments used in precision
measurement. Consists of comparisons of two instruments, one of which is certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being compared.
g. Install. The act of emplacing, seating, or fixing
into position an item, part, module (component or assembly) in a manner to allow the proper functioning of the
equipment or system.
h. Replace. The act of substituting a serviceable like
type part, subassembly, or module (component or assembly) or an unserviceable counterpart.
i. Repair. The application of maintenance services
(inspect, test, service, adjust, align, calibrate, replace)
or other maintenance actions (welding, grinding, riveting, straightening, facing, remachining, or resurfacing) to restore serviceability to an item by correcting
specific damage, fault, malfunction, or failure in a
part, subassembly, module (component or assembly),
end item, or system.
j. Overhaul. That maintenance effort (service/action) necessary to restore an item to a completely
serviceable/operational condition as prescribed by
maintenance standards (i.e., DMWR) in appropriate
technical publications. Overhaul is normally the highest
degree of maintenance performed by the Army. Overhaul does not normally return and item to like new condition.
k. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable equipment to a
like new condition in accordance with original manufacturing standards. Rebuild is the highest degree of
materiel maintenance applied to Army equipment.
The rebuild operation includes the act of returning to
zero those age measurements (hours, miles, etc.) considered in classifying Army equipments/components.
D-3. Column Entries (Section II)
a. Column 1, Group Number. Column 1 lists group
numbers, the purpose of which is to identify components, assemblies, subassemblies, and modules with
the next higher assembly.
b. Column 2, Component/Assembly. Column 2 contains the noun names of components, assemblies, subassemblies, and modules for which maintenance is authorized.
c. Column 3, Maintenance Functions. Column 3 lists
the functions to be performed on the item listed in column 2. When items are listed without maintenance
functions, it is solely for the purpose of having the
group numbers in the MAC and RPSTL coincide.
d. Column 4, Maintenance Category. Column 4 specifies, by the listing of a “worktime” figure in the appropriate subcolumn(s), the lowest level of maintenance authorized to perform the function listed in column 3. This figure represents the active time required
to perform that maintenance function at the indicated
category of maintenance. If the number of complexity
of the tasks within the listed maintenance function
D-1
TM 11-5805-637-12
vary at different maintenance categories, approximate
“worktime” figures will be shown for each category.
The number of task-hours specified by the “worktime”
figure represents the average time required to restore
an item (assembly, subassembly, component, module,
end item or system) to a serviceable condition under
typical field operating conditions. This time includes
preparation time, troubleshooting time, and quality
assurance/quality control time in addition to the time
required to perform the specific tasks identified for
the maintenance functions authorized in the maintenance allocation chart. Subcolumns of column 4 are as
follows:
C–Operator/Crew
O–Organizational
F–Direct Support
H–General Support
D–Depot
e. Column 5, Tools and Equipment. Column 5 specifies by code, those common tool sets (not individual
tools) and special tools, test, and support equipment
required to perform the designated function.
f. Column 6, Remarks. Column 6 contains an alphabetic code which leads to the remark in Section IV, Remarks, which is pertinent to the item opposite the partitular code.
D-2
D-4. Tool and Test Equipment Requirements (Section III)
a. Tool or Test Equipment Reference Code. T h e
numbers in this column coincide with numbers used in
the tools and equipment column of the MAC. The numbers indicate the applicable tool or test equipment for
the maintenance functions.
b. Maintenance Category. The codes in this column
indicate the maintenance category allocated the tool or
test equipment.
c. Nomenclature. This column lists the noun name
and nomenclature of the tools and test equipment required to perform the maintenance functions.
d. Tool Number. This column lists the manufacturer’s part number of the tool followed by the Federal
Supply Code for manufacturers (5 digit) in parentheses.
