I use a Harris ts-22 butt set to test tn2224cp dig ports at remote locations It does not have a data detect option. In the monitor position you will hear white noise if a digital set is hooked up and you will hear a high pitched noise if no set is present. When you go off hook on you butt set you will hear clicking noise with or without a set present.
