In the event of a power outage, your phone service won’t work unless there’s a battery backup or an uninterruptible power supply (UPS) connected to the phone modem.

Battery backups by model and available options

  • Most older models of phone modems, such as the ARRIS TG2472 and our RCA models, include a built-in battery.
  • Our DOCSIS 3.1 modems, such as the TG3452 and Hitron CODA-4589, have an optional battery that you can buy from Cogeco.
  • Newer models and most fibre modems, such as our F@st and Calix 803 or Calix 812 models, do not have a battery backup option.
    • For these models, you can buy a UPS from a third party. It’s your responsibility to replace the battery when necessary.
    • If your modem connects to other networking equipment, such as a phone switch, that device would also need to be connected to a UPS for phone service to work during a power outage.

Battery capacity and usage

  • A modem battery allows your phone service to work during a power outage, including for making calls to 911 and for connected alarm systems.
  • A fully charged modem battery can last between 4 and 8 hours, depending on usage.
  • Cordless phones will not work during a power outage unless the base is connected to a UPS.
