Using the DMT tool and comparing older charts with a current one i can see several tones that appear to have been somewhat depleated but my main concern is missing tones
I have 2 Gaps
Gap 1 246kHz - 259kHz (Tone 57-Tone 59)
Gap 2 2053kHz - 2156kHz (Tone 476 - Tone 499)
Asdl tone info
As I'm a BE customer should the tones in Gap 2 be present ?
