The Mitel® Line Interface Module is a discrete optional module that integrates into the dual mode Mitel 5224 and 5235 IP Phones and provides a separate connection to an analog line, such as that included with a DSL service.
In the event of a wide area network failure the phone automatically uses the PSTN to provide continued basic telephony until service in restored. The teleworker can use the analog line for emergency calls and for local calling. A lit line appearance and ringing on each phone identifies an incoming call. |
