The Line Quality of 19 is good for that speed. That means that at least
the modem would probably go faster if it could. However, if you see a
Quality of 19 at 26.4, I suspect that the phone lines won't support Flex.
You might get 28.8, or even 31.2 out of them if the sun is shining. That
judgement is just based on things I have learned from v.34 modems though,
so it may need to be adjusted slightly.
Line QUALITY................ 019
Receive LEVEL............... 023
