Abstract

PURPOSE:To test switchboards to be tested from a pseudo-call centralized generation station through a public telephone circuit by generating various pseudo calls, by providing the pseudo-call centralized generation station at distance. CONSTITUTION:A tester for a switchboard 31 to be tested which requires a pseudo call forms a data link to a centralized pseudo-call generation station 20 through a data terminal equipment 33 consisting of an NCU (network controller) and an MODEM (modulator and demodulator). Consequently, commands from a typewriter 32 are sent to a CC25 (central controller) via the route of the typewriter 32, the terminal equipment 33, an LS (subscriber station) switchboard 41, an analog circuit group 22, an analog switchboard 42, a data terminal equipment 26, a remote typewriter controller (RTPC)27, and the CC. Under the commnds from the typewriter 32, a call generator 24 is actuated and a pseudo call requested for the switchboard 31 to be tested by the command is generated through a communication network.
