I will have to see if I can find the booklet I was given - I think I still have it somewhere. The general rule was that I was not to use the area frequency except in the event of an emergency. I provided information on wind direction, speed, temperature etc. which all came from a direct telephone link to the AWS which the Met Bureau installed in my office. I also asked incoming aircraft if they required fuel, if I didn't already know that. On at least two occasions I was able to provide traffic locations to aircraft who were trying to communicate with foreign students without success. Also had several incidents of aircraft with unsafe landing gear indications, as well as a couple of crashes off aerodrome where it was quicker for me to use the radio to contact Flight Service than it was to use the phone.
