Hi. I've ordered BT Infinity 2 and now waiting a month before install! Anyway I believe the install is done yourself now, which is OK. But I only have a NTE5 master socket. Hardwired into it is an ADT alarm system (about 18 months old). My current ADSL2 connection is fine so am I correct in thinking that the ADT system has its own filter and will not cause an issue come Infinity 2 time? Or do I need to get hold of ADT to sort it out, or should this be OR responsibility.
