Longer BEARER_CONNECTION_MONITOR_TIMEOUT?

[colin.helliwell at ln-systems.com]

I've been finding today that I'm getting failed connection attempts  - it
looks like MM is checking the PDP ("+CGDACT?") whilst ppp/modem are still in
the process of getting themselves together. So MM is getting back an
'inactive' response and, I think ditching the attempt.
I've increased BEARER_CONNECTION_MONITOR_TIMEOUT and that seems to address
it. 
Not sure if the time taken is down to the Operator or to signal quality
(which isn't great here), but wondered if it was a situation other people
encounter?
