LEARNING EVENT 5: SYSTEM CONFIGURATION
1. Capabilities. The AN/TSC-85B/93B terminal configurations allow digital interface with TRI-TAC
equipment and MSE. They also provide limited capability for analog input and an ECCM capability for
operation in a stressed environment. The baseband improvement modification incorporated replacing the TD-
660s, TD-1065s, TD-1069s, KG-27s, and adding the antijam/control modem (AJ/CM), LRM/TD-1389, and
KG-94A. Upon completing the program, the modified terminals were redesignated as AN/TSC-85B/93B.
2. AN/TSC-85B. Four TD-660s and TD-1065s were replaced by four TD-1389s to function as the
multichannel multiplexer for unstressed/clear mode communications. Two CV-1548 telephone signal
converters and two MX-9635 echo suppressors were removed and two CV-1548s and MX-9635s will remain.
These two unit pairs will remain to support use of two-wire telephones. Four TD-1069s or their reserved cavity
locations, were removed and replaced by four TD-1389s to function primarily as a multiplexer for the AJ/CM,
or alternately as a submultiplexer into another TD-1389. Eight TD-1389s will be installed in each AN/TSC-
85B. Sufficient crosspatch capability was provided to permit any TD-1389 to function in any role. Baseband
patching will be available to provide access to all baseband ports on the shelter entry panels. This will allow the
individual channels of the CV-1548/MX-9635 to be patched into any user channel as required. In addition, four
KG-27s were replaced by four KG-94As to provide bulk encryption for four unstressed/clear mode
multichannel groups. A nodal terminal AJ/CM will be installed. It will provide an antijamming
communications channel and will replace the FM control orderwire. Four STU-III/equivalent 2.4 kb/s secure
voice devices will be added to provide an AJ/CM stress mode secure voice capability. All other items in the
terminal will remain the same.
3. AN/TSC-93B. Two TD-660s and two TD-1065s were replaced by one TD-1389 to function as the
multichannel multiplexer for unstressed/clear mode traffic. One CV-1548 and one MX-9635 were removed and
one of each will remain to support use to two-wire telephones. One TD-1069, or its reserved location, was
removed and replaced with one TD-1389 to function primarily as a multiplexer for the AJ/CM or alternately as
a submultiplexer into another LRM/TD-1389. A total of two LRM/TD-1389s were installed.
