3. Terminal Base Address (TBA) Management
a. All DAMA capable terminals must have a valid, unique TBA to operate in a
DAMA network. A TBA identifies the radio on the DAMA network and in the DAMA
controllers at the SMC. TBAs cannot be shared by terminals in a DAMA network. A
TBA functions in a DAMA network much like an IP address functions in a computer
network. For those radios with more than one port, additional addresses are required
and known as port addresses. Space and Naval Warfare Systems Command (SPAWAR)
Charleston, South Carolina assigns these port addresses based on the type of terminal
for which the unit requests an address. Joint UHF MILSATCOM DAMA maintains a
list of all TBAs in the call directory, fleet satellite communications system (FSCS)-211-
80-29-2. This directory may be downloaded periodically from SPAWAR’s Charleston,
South Carolina Web site, http://sscc.spawar.navy.mil/ or contact SPAWAR’s
Charleston, South Carolina TBA administrator at commerical phone number (COMM)
(843) 218-6620 or defense switched network (DSN) 588-6620.
III-6
b. Units request TBA from their higher headquarters to preclude proliferation of
unnecessary TBA. The headquarters coordinate with SPAWAR to acquire the required
TBAs. This ensures major commands have oversight of the procured TBAs available to
their units. Units should not interact with SPAWAR on a regular basis.
FSCS-217-98-00-1 provides guidance for requesting. (Point of contact at SPAWAR is
COMM (843) 218-6620.) Requests for TBAs should allow a 30 day turn around time for
the addresses to ensure the TBA is properly entered in the worldwide JMINI and SAC
databases and the TBA is recognized when it logs onto the network to access DAMA
network resources. Most units receiving the terminals must submit SARs in a timely
manner, therefore address requests should take place 60 to 90 days before receipt of
radios.
4. Orderwire (OW) Key Management
a. Unit COMSEC custodians maintain the OW keys used in DAMA. For a unit that
does not have keys available, the COMSEC custodian orders the keys from—
(1) Joint Chiefs of Staff ICP Manager, 7115 South Boundary Blvd, MacDill AFB,
FL 33608-2461.
(2) COMM (813) 828-2461 or DSN 968-2461.
Note: Only the requesting unit's COMSEC custodian with valid COMSEC
account is authorized to order these keys. The DAMA system consists of
four satellite coverage areas. Each satellite coverage area has a unique
OW key. The requesting activity must specify the satellite coverage area,
for example, continental United States (CONUS), Atlantic (LANT), Indian
Ocean (IO), or Pacific (PAC) for the OW key requested. The COMSEC
custodian receives a message stating which key segment is used for the
WEEKLY key.
b. The DAMA SAC and JMINI initial operational capability use keys in positions 0
to 7 while, the AN/PSC-5A (Spitfire) uses keys in positions 1 to 8. Careful coordination
is performed before executing any DAMA operations. Additionally, the key location
must be coordinated in each footprint that operations occur to ensure compatibility with
the DAMA controller in all areas of operation. A good technique is placing the same key
in the first four fill positions. The other four positions are reserved for future
over-the-air rekeying capabilities. The NCTAMS places the keys in the positions
indicated in Table III-2. Coordination is required to determine the key position for the
current week.

Accessing a Dedicated Channel
a. A dedicated channel is a 5-kHz or 25-kHz satellite channel (uplink and downlink
frequency pair on a transponder) supporting a single communications network for a
designated period of time.
III-9
b. User requirements—
(1) Azimuth and elevation to satellite.
(2) Home channel/frequency pair/uplink and offset. (See Appendix A to verify
home channel number based on frequency pair.)
(3) COMSEC type, mode of operations, and data rate.
7. Accessing a DAMA Channel
a. Description—DAMA (called “demand assignment multiple access in the MIL-
STDs- is also correct) is a method of automated channel-sharing (multiplexing). User
terminals automatically interact with a control station, which allocates a portion of a
satellite channel for that terminal’s communications. Channel allocation is based on
current needs and priorities. Any unused DAMA resource is available on a precedence
basis and is shared by all users. The ad hoc nature of DAMA limits the waste caused by
long-term preassigned satellite resources. Channel-sharing is transparent to the
TACSAT user. Since there are two types of UHF satellite channels, 5-kHz and 25-kHz,
there are two types of DAMA.
b. User requirements—
(1) Azimuth and elevation to satellite.
(2) Home channel/frequency pair/uplink and offset. (See Appendix A to verify
home channel number based on frequency pair.)
(3) COMSEC type, mode of operations, and data rate.
(4) OW key and position.
(5) Type of channel—5-kHz or 25-kHz.
(6) Configuration code.
(7) Type of communications—normal, silent, EMCON.
(8) TBAs with assigned maximum precedence and net guard addresses.
(9) Demarcation number for 5-kHz DAMA.
(10) Type of ranging.
(11) Types of services
(a) 5-kHz—message, circuit, or DASA.
(b) 25-kHz—two-party or conference calls.
c. Fundamentals of DAMA operations—
(1) Acquiring the satellite. All terminals must be able to receive and decrypt
OWs transmitted by the DAMA controllers. Unless this is accomplished by the
individual terminal, access to the satellite channel is not obtained. The OWs include
the information required to decrypt messages. Common problems are using the wrong
OW key and placing the OW key in the wrong position.
(2) Ranging. For terminals to transmit in the proper time-slot, the radios must
have range reaching the satellite. Active ranging may be performed by the terminal. It
III-10
automatically determines the range and provides the information required for
transmissions. Passive ranging is an option where a terminal computes the range to
the satellite based on the terminal position, zulu time (z), and satellite ephemeris data
to obtain the information required for transmissions.
(3) Logging in. While terminology is different between the two types of DAMA,
each terminal must inform the controller the terminal is accessing the channel.
(a) In 5-kHz DAMA, the radio sends a log in message providing the
terminal information to the controller.
(b) In 25-kHz DAMA, the radio sends a status B message providing the
terminal information to the controller.
(4) Establishing communications. When the terminal completes the previous
steps, it must still request permission to access the channel.
(a) To communicate on 5-kHz DAMA, the type of service or call must be
decided before establishing communications with other terminals. The service or call is
limited to one address, so either a point-to-point or a net guard call is made. The types
of calls are circuit service, DASA service, and message service. Once communication is
complete, the call or service is automatically terminated or the operator terminates the
call or service manually. This releases the time-slot to be used by other terminals. The
system permits the controller to terminate the call or service, in case an operator
forgets, so the time-slot is available to other terminals.
(b) To communicate on 25-kHz DAMA, a call or service must be established
with the other terminals. The call or service is made to a net guard address, another
terminal address, or a conference call (up to six terminal addresses or a mixture of one
net guard address and terminal addresses). Once the call or service is established, the
individual terminal notifies the operator that communication is possible. In a true
DAMA environment, the operators use the time-slot assigned for transmissions and
then return the resource by tearing down/completing the call so others may use the
time-slot.
(5) Completing communications.
(a) In 5-kHz DAMA, completion of the call or service is based on the type of
service established. With a message service, the call or service automatically
terminates once the data is sent and received by the terminals. With a DASA service,
the operator must request a time limit (5 to 5115 minutes or indefinite, which is 5115
minutes). The call or service automatically terminates when the time expires. For a
circuit service, the individual operator terminates the call or service. In addition, the
controller monitors the service for communications and if none are detected, the
controller terminates the call or service.
(b) In 25-kHz DAMA, completion of the call or service is based on channel
set up. The operators may establish the communications with a time limit (01 to 59
seconds, minutes, hours, or days). Once the time limit is reached, the call or service
automatically terminates, releasing the time-slot. If a time limit is not set, the
operators must initiate the completion of the call or service. If the channel is set up so
time-slots are preassigned (also known as TDMA DAMA), the time-slot is not released
and completion of the call or service is not performed by the operator.
III-11
(6) Logging out.
(a) For 5-kHz DAMA, a log out message must be transmitted to notify the
controller the terminal is leaving the channel. Failure to send the log out OW effects
terminals when they reaccess the DAMA channels. Terminals on a 5-kHz DAMA
channel are monitored continuously and can be logged out by the control station when
they do not respond to periodic polling. This time limit is normally set at 30 minutes.
(b) For 25-kHz DAMA, an out of order service OW is transmitted to the
controller. This OW notifies the controller to take the terminal off line. The OW
requires use of a reason code. To date, 99 is the only code identified. Failure to send
the OW does not effect the terminal’s ability to reaccess the channel.
d. Common DAMA challenges.
(1) Wrong OW key loaded, OW key loaded in the wrong position or control
station has wrong OW key.
(2) Radio programmed improperly.
(3) Radio not programmed or contained incorrect TBA.
(4) Guard list loaded improperly in the radio.
(5) Radio loaded with the wrong home channel number/frequencies.
(6) JMINI or SAC improperly programmed at the NCTAMS.
(7) NCTAMS problems.

3. Dedicated UHF SATCOM Operational Steps
a. To operate in dedicated UHF SATCOM mode, connect a medium or high gain
SATCOM antenna to VHF-HI/UHF J8 antenna connector with a coax cable. Analyze
terrain in planned areas of operation for satellite look-angle access. Verify the
SATCOM antenna is correctly oriented using a magnetic compass to point the antenna
on the proper horizontal azimuth to the satellite. Make an approximate antenna vertical
elevation adjustment. Pointing graphs and look-angle calculation software may assist
in this task. Azimuths from these graphs are not adjusted for local magnetic
declination. Table C-5 contains UHF satellite positions. To check SATCOM antenna

Note: The SATCOM RSSI test can be conducted only by using data operating
parameters of 1200 or 2400 bps. Preselect data operation using KG-84 or
ANDVT at one of these rates before initiating the test.
(1) After placing the AN/PRC-117F into normal mode dedicated SATCOM
operation, press the CALL button on the KDU.
(2) Press ENT to initiate the SATCOM RSSI test.
(3) Watch display for test completion. A relative signal strength score is
displayed with a value from 000 to 100. Repeat test and adjust pointing of the
SATCOM antenna to obtain a better than 80 score.
(4) Press CLR to exit SATCOM RSSI test.
b. Perform the following procedure for dedicated UHF SATCOM operation:
(1) Rotate function switch to cipher text (CT) or TD. The AN/PRC-117F does not
allow plain text (PT) non-secure voice operation in SATCOM to operate in a non-secure
SATCOM mode. The radio defaults to DATA only operation when PT is selected.
(2) After the radio initializes, press MODE.
(3) At the OPERATIONAL MODE prompt, select NORMAL; press ENT.
(4) Select the desired SATCOM net preset by pressing the PRE + or - switch.
(5) Begin radio operation. See Figure C-3 for SATCOM operational displays.
4. SATCOM 181B Data Operation Using KG-84 COMSEC and Continuous
Phase Modulation
a. When using a SATCOM net preset using KG-84 COMSEC and Continuous Phase
Modulation (CPM) modulation, the sender transmitting station decides in which CPM
data option to conduct the transmission. The receiving end must also use a CPM data
code of the same channel type. To change the data option code for the currently selected
SATCOM net preset—
(1) Press the circular arrow key to view the data option page of the SATCOM net
preset. See Figure C-3 for SATCOM displays.
(2) Use left/right arrow key to scroll over to data option field. With the up/down
arrow key, select the required code. Only the data option codes relating to the presently
selected COMSEC mode and/or satellite channel type can be selected.
C-6
(3) Refer to Table C-6 AN/PRC-117F DAMA SATCOM capabilities. If COMSEC
mode needs to be changed to achieve required data option, use the COMSEC menu
under OPT key.
Figure C-3. Dedicated UHF SATCOM Displays
b. To send SATCOM DATA with CPM data option—
(1) Ensure net communications plan is for all outstations to use a CPM data
option from Table C-7 for the same channel type (5-kHz or 25-kHz). A synchronous data
transmission application is best.
(2) Sending station selects the desired CPM data option with which to transmit
the data message. On transmitting the message, the receiving radio automatically
matches speed of the sending station.
(3) If transmission is unsuccessful, (the receiving end does not acknowledge good
reception), it may be necessary to reduce the CPM data rate and re-attempt the data
transmission. If transmissions continue to be unsuccessful, troubleshoot the
communications software set up to determine the communications failure.

5. AN/PSC-117F DAMA UHF SATCOM
a. UHF DAMA SATCOM is a separate mode of operation in the AN/PRC-117F.
DAMA operation is available on 5-kHz and 25-kHz UHF SATCOM channels that have
been converted to DAMA control. THE 25-kHz DAMA is operated in either automatic
control (AC) or distributed control (DC). Refer to Table C-6 AN/PRC-117F DAMA
SATCOM for capabilites.
