International ClassH04M 011/06AbstractCall data signals actuated by a telephone terminal are provided from a telephone communication system to indicate call data as the called number, the calling number and the calling equipment. The call data signals address related control functions for interfacing a multiple-format multiple-port data processing system. Screening tests and format selection for the processing system are performed. Individual telephone terminals and individual data formats are interfaced under controlled conditions specified by the call data. Time tests, history tests and demographic tests are executed in addition to basic qualification tests. Control is executed from active data storage for assembled control words and record words. Record words for individual calls are stored along with developed billing data.Other References
