Handset Question?

[StumblingForward]

The system I work with has both analog and digital lines. I have a Harris TS22A speakerphone handset I use to test my analog lines but I was wondering if there is a handset that will test both digital and analog phone lines, I am putting in more and more digital stations it seems and it would be easer to carry around the handset and test my lines than to carry around a phone to do my testing.
Any suggestions

Your harris but set will only give you a high pitch when it see's a digital line. or Stick your toner on the line. The led should change when it see's a digital line.

Yes this is true
What I am looking for is a handset that works for analog AND digital all in the same handset.
