Narrative:

In the area described above I was working approximately 15 aircraft when the radar, frequency, and land lines failed. The radar was out for 10-15 mins, the frequency for 4-5 mins and land lines for at least 1 hour. It is impossible to establish non-radar separation when all the aircraft are at the same 2 or 3 altitudes, at these speeds and density.
