I need to remotely power cycle the modem now and then.

Why?

If it's fallen over and lost the link you won't be able to remotely
do anything.

If a bad line or noise has knocked the speed down ADSL2+ recovers
quite quickly on it's own (unlike ADSL which can take up to 72
hours).

If the modem and/or DSLAM has got it's knickers in a twist over the
required signal to noise level a reboot won't affect that. You need
to start the 10 day training period, this instruction has to come
from your ISP most like as a result of you calling/emailing support
or via a webpage on your account details.

The last is the only one that occurs here. The modem stays up until
either there is a power cut long enough for the UPS to flatten it's
batteries or I switch it off to do "maintenance".

Personally I'd VPN into the home network and access the devices web
interface over that to restart the link or reboot the device. Then
sit nervously waiting for it to come back up...
