Narrative:

We have a continuing condition with our landlines and frequencys. We have an old 301A telephone company system not compatible with the new icss. We get tones over the landlines with some icss facilities ie, N90, baf. Also our UHF frequencys have blind spots and on many occasions we need to use back-up receivers or other frequencys. Also lately we are getting squelch tones on 125.8 (varying intensities but consistent), 123.95 (weak and occasional), and 125.65 (for 2 days but seems to have stopped now. We have 1 controller on a medical waiver for hearing loss and several ca-1's on file from controllers getting tones over frequencys and landlines. Callback conversation with reporter revealed the following information: reporter indicated that action is being taken to resolve the problems as a result of a facility evaluation and 2 ucrs. Reporter indicated that he used a handset for landline communication which allows him to remove the set from his ear quickly when a tone is detected. Reporter said that some equipment parts are not available and that it might take 18- 24 months to get the parts. Reporter appeared to be satisfied that work is being done to correct the problem.
