This Thelephone Terminal Group was housed in a S-180/MTA-4 (modified S-141/G) and later in a modified S-280B/G Shelter. The AN/MTA-4A is together with the AN/MTA-3A Thelephone Switchboard Group part of the AN/MTC-1 Central Office, Telephone, Manual. The shelter on the photographs is still a S-180/MTA-4 apparently modified to MTA-4A standards:
