The AN/MTC-1 and -1A were air- or vehicular-transportable manual central offices which provided switching for 196 local battery or common battery subscriber lines and 20 manual or dial trunk circuits. The AN/MTC-1 and the -1A were each housed in two shelters, the AN/MTA-3 and AN/MTA-4. The MTA-3 contained three parallel switchboard positions. The AN/MTA-4 housed the relays, frames, storage batteries, and power panel. The AN/MTC-1 or the -1A was used at signal centers in the corps area communication systems.
