I currently manage two FTTC connections. I ditched the supplied Openreach modem on both sites on install day. On one I use a Cisco 887VA router and on the other a Draytek 2850 router. Both work perfectly and are a neater one box solution than the standard setup offers. Use of such devices does breach Openreach's terms & conditions though.
I've kept the original Openreach modems should there be a line fault that needs to be investigated.
I installed both routers with the commissioning BT engineers present and neither was aware the connection could be used without the Openreach modem!
