The AN/MTC-9 was housed in two semitrailer vans, the AN~MTA-5 and the AN~MTA-7. The AN/MTA-5 contained the relays, frames, storage batteries, and power panel. The AN/MTA-7 housed nine switchboards cabled in a four-panel multiple arrangement. The AN/MTC-9 was used at army signal centers in an area type communications system.
