@harju -- a Shaw technician told me that the Shaw Phone adapter requires a lesser amount of signal than their cable-modem and TV boxes.
So, if you have a 3-way splitter labelled "3.5, 3.5, 7 decibels", connect the Phone adapter to the "7".
I have my phone connected to the XB7 modem. It works fine. I bought a headless smart phone system from Motorola to control the satellite phones around the house from the XB7. Alternatively I could have requested a Shaw tech to come in and activate the jack nearest the XB7 box and carry on with a head unit in another room like my office. It was more convenient at the time to buy a new phone system as my old phones were in need of replacement. Either way the XB6 and 7 boxes are ready for phone connection.
