We have a number of conditions that must be met for your line to be switched to a 17a Spectrum profile.
If your line is on the 17a spectrum profile, but the spectrum between 8Mhz and 17Mhz is not being used, I'd be looking at your CPE. it shouldn't report 17a unless the DSLAM is providing that, and we run 8b and 17a on independant profiles.
As for the question of 'what allows a line to be on 17a':
- The current bandplan is 8b (goes without saying!)
- The line is shorter than 350 meters, which is an electrical length in the 5530 Network Analyser of <7dB
- DLM is in operation on that line
- A Bandplan switch hasn't occured in the last 90 days (to stop bouncing between 8b+17a, while still allowing re-evaluation as/when required)
