DLM on FTTC

[#1]

Was thinking of either getting a different modem or having another go at trying to get the Thomson in to DMZ mode for my PS3 (something i could never manage on ADSL).
Which unit does the DLM keep an eye on? Is it the BT modem or the modified Thomson Router? In other words would the DLM notice if the Thomson is being disconnected whilst I play around with it as long as the BT Modem remains connected and untouched.

DLM looks at sync and only sync. Play with the Thomson as much as you like

I'd just recommend clicking disconnect in the Thomson GUI before you do so that it logs you off properly, when you plug it back in we've seen that the session may still be up but the router can't drop it until you reboot the BT modem.
