Appendix B
Information Request Codes
Table B-1. Information Request Codes
Note: If action states contact NCTAMS – the RSSCs may be contacted for assistance.
Code Condition Action
1 to 3 Not used. None.
4 Disconnect constant key offender.
The controller determined a constant key
offender should be disconnected.
5 to 65 Not used. None.
66 Terminal type cannot be connected to the
requested guard number.
The requested guard number is
associated with terminals built to a
different version of the MIL-STD. Check
the guard number and try connecting
again.
FSCS or 183A terminal requested to
connect to a guard number associated
with 183 (baseline) terminals.
183 (baseline) terminal requested to
connect to a guard number associated
with FSCS and 183A terminals
Terminal has been transmitting for 17
minutes—waveform does not allow for
constant transmission. AN/PSC-5 terminal
does not provide a means to bypass this rule,
so all transmissions must be less than 17
consecutive minutes.
Information request code 66 is sent when a
user requests to join/start a network service
using the wrong network address.
MIL-STD 188-183(-) uses the odd numbered
(primary) address; this is the AN/PSC-5,
AN/PRC-117F, and so forth.
FSCS and MIL-STD 188-183(A) use the even
numbered (alternate = primary + 1); for now
this is the TD-1271, since there are not any
certified 188-183(A) terminals yet.
Note: 117F and AN/PSC-5D are pending
upgrade to 183B capability.)
The new DAMA SAC channel controller
software links the even/odd network address
pair to maintain interoperability between all
terminal types.
Example VOICE CMD NET:
Primary network address: 56001 for MIL-STD
188-183 (-).
Alternate network address: 56002 for TD-1271
and MIL-STD 188-183A terminals. The
DAMA SAC links 56001 and 56002 in its
software to the same data slot. Use of 56001
is required in the AN/PSC-5. Any TD-1271
and MIL-STD 188-183A terminals would use
56002.
