None of that information is actually useful in this situation. You want to find your Signal Noise Margin (Might also be designated at dB, NMR, or SNR). It should be at least 10.0 or higher on both the upstream and downstream signal.
When calling support:
1. ask what speed profile you are set to.
2. Ask what relcaps (relative capaicty) your line is showing right now. This is the amount of signal they have to pump to you to keep the circuit alive. If it gets over 85% on the downstream, it may be unstable. If it's above 85% on the upstream, it's probably a wiring/install issue on your end.
3. Ask what your noise margins are. They should be above 10.0 (as stated above).
Setting the profile to Interleave is very easy for them to do unless your circuit is on a remote terminal. If I had your phone number and zip code I'd be able to tell you more about your circuit that would be helpful
