Cisco IP DECT 6800 Series Introduction

The handsets communicate with the base station using Digital Enhanced Cordless Telecommunications (DECT). The base station communicates with a third-party call control system for call control functions.

You can have one or more base stations in your site. Multiple base stations extend radio coverage for larger office spaces. You can also set up multicell systems. Each base station can have up to 30 handsets configured to use the base station, but the number of active calls on a base station is limited.

Upgrade the Firmware

You can upgrade the base station and handset firmware with TFTP, HTTP, or HTTPS. You upgrade the base station first. After the upgrade, the base station automatically reboots. Then you upgrade the handsets, which automatically reboot.

You access the Cisco Software Download page to get the firmware in zip files. The zip files contain these firmware files:

  • For the base station, the zip filename starts with IPDECT-DBS210

  • For the handset, the zip filename start with IPDECT-PH6825

For detailed information about the upgrade procedure, refer to the "Maintenance" chapter in the Cisco IP DECT 6800 Series Administration Guide.
