19. AN/TTC-47 NCS.
Status: To be determined; NSN: To be determined
General Information
The NCS is configured in two S-250( )/G shelters-a wit g shelter and an operations shelter, each
transported on an M-1037 (HMMWV). The NCS is the hub of the MSE node providing network
interface for the subscriber access elements. The ON-306/TTC-47 switching shelter provides the
external interface, circuit switching, and associated functions. The OL-413/TTC-47 operations shelter
provides the central processing and operator interface functions. The NCS provides automatic
subscriber finding features which allow permanent subscriber address assignment and negates the need
for knowledge of subscriber geographical location and switch affiliation at the subscriber level. Power
to both assemblages is provided by a PU-753/M, 10-kW, trailer-mounted, diesel generator.
