A RINGING GENERATOR TESTING ARRANGEMENT FOR A DIGITAL TELEPHONE NETWORK ABSTRACT OF THE DISCLOSURE A ringing generator testing arrangement for a digital telephone network is shown comprising a zero crossing detector connected to the ring lead of a line circuit under test. The zero crossing detector gates a clock signal into a counter circuit during the negative to positive transition of the ringing generator signal positive half cycle. The counter circuit advances until the next positive to negative transition of the ringing generator signal. At this time, the zero crossing detector cuts off the clock signal and the counter circuit transmits to a central control complex a count representing a measured interval of the ringing generator positive half cycle.
