The Com-Power IS 268 Impedance Test Set is designed to analyze AC and DC on hook impedance of a telephone interface device. The AC and DC on-hook impedance during ringing tests were designed to protect the telephone network from excessive current flow while on-hook.
The IS268 test set works for AC and DC on-hook impedance during ringing tests to ensure that the EUT does not cause the ring trip equipment at the central office to disconnect prematurely. This test is also used to calculate the ringer equivalence number
