There are many factors that prevent us from delivering this service to some customers; these include:

The length of wire that connects your residential phone line to the Bell Canada Central Office may be too long. It is the measurement of the wire that determines whether a customer is inside or outside the boundry of availability. The range for high speed ADSL service must be within a loop length of 4.5 km from the Central Office. This distance may not always appear far, but telephone lines do not follow straight lines to a house and a considerable distance may have been added to the wire in order to reach your home.

There are two telephone lines installed in the house that share the same physical copper wire. This telephone line configuration is referred to as Added Main Line (AML) and is not compatible with the High Speed ADSL service.

The technology required to provide the High Speed ADSL service has not been installed in the Bell Canada Central Office to which your phone line is connected. Although this technology is currently accessible to more than 2 million households in Ontario and Quebec, not all of Bell's Central Offices in the serving areas have been equipped.

Unfortunately, if your telephone line connects to the Central Office via a 'remote office' which does not use copper wire then the line will not be compatible with our High Speed ADSL service. This particular technology was devised to provide telephone service to developing areas; research is being performed to determine a solution to this short coming.

The telephone network was developed in stages, over a great period of time, to meet increased demands in expanding geographic areas. Due to demographic growth and various technological methods used at different times, some of the distribution patterns that were utilized to provide telephone service to neibourhoods may have resulted in line conditions that are not compatible with the High Speed ADSL service.
