Will my home alarm or other equipment work with fibre-to-the-home (FTTH) technology?

If your Bell Home phone or Bell Internet services run on fibre-to-the-home technology (FTTH), you may have problems using older equipment designed for regular copper phone lines.

Types of older equipment may include:

  • Home alarm systems
  • Fax machines
  • Dial-up modems
  • Teletypewriters (TTY)

To find out if your devices are fibre optic compatible, please contact the equipment manufacturer.

If you have a home alarm system:

Most home alarm services should work normally. However, some older alarm systems that use the telephone to alert the alarm company may require adjustments. Contact your home alarm manufacturer or service provider for FTTH compatibility information.

Note: Bell will perform up to three brief FTTH upgrades per year, each lasting up to 14 minutes. During these upgrades, your Bell Home phone service (including 9-1-1) will be unavailable. Your alarm will continue to function, but may not be able to communicate back to your service provider using your Home phone or Internet service.

If you have a teletypewriter (TTY):

If you use a teletypewriter with your FTTH service, please make sure it is not set to a high speed setting (90 baud). Bell Relay service (BRS) does not support this setting on copper technology and will not support it on fibre-to-the-home.
