Comcast Business Phone Modem

On the Comcast Business Phone Modem what is the purpose of the single Ethernet jack on the device? These are the modems that have COAXIAL going in for COMCAST signal and support up to 8 voice lines. Never seen one of these ethernet ports connected to  a local network, but saw one the other day and just wondering if that was done by mistake. Thank you.

Hello, I hope all is well. The modems are manufactured with that hardware in them, but we choose to only keep the phone ports active. It's not a mistake! I hope all services are working as expected. If you have any further questions please let us know.
