CAMA-C IBM System/7 Main Cabinet
CAMA-C replaced the method of recording detailed billing information of customer-dialed calls in CAMA-equipped toll switching machines. CAMA-C utilized a high-speed minicomputer an IBM System/7 to replace the 28 channel paper-tape
perforators and the master timer in existing crossbar tandem and/or 4A installations. Created tapes could be processed at the AMARC center which used DEC PDP 11/70's Mini Computers.
