Probably due to an error before page data transmission.

Timing.  Same problem as above.  See below.

Stick with Class 1.

These are both the same problem: timing.

This is the last time we hear from the remote.

This is Class1SendMsgDelay.

All of this has been pure transmission, and so we've not heard a peep 
(intentionally) from the remote.

And now, when we want to hear from the remote - it's not there.  It may 
still be connected, but it's not expecting MPS.  It's expecting something 
else.

Try changing Class1SendMsgDelay in your config file.  Try 95 and 55 ms (75 
is default).
