Available Backup Power Options
Backup batteries are rated by the manufacturer to last for different time periods up to 24 hours. Backup batteries for your Northland telephone services are available from Northland or directly from our supplier http://shop.surfboard.com/arris-telephony-modem-back-up-batteries. If you choose to buy a back-up battery directly, make sure you choose a battery that is compatible with your terminal adapter model. If batteries are not available for your model, you may contact us to request a replacement model that supports battery backup.
Performance and Monitoring of Your Battery
Battery life estimates are not guaranteed. The battery is intended to support short, emergency or other urgent telephone calls. You are solely responsible for testing, monitoring, and replacing your batteries on a regular basis. We do not guarantee uninterrupted telephone services even to customers that have working backup batteries or other power supplies. Our network may experience other problems that would prevent normal operation of your services even if you supply power to your devices.
