Connecting a Home Security System to Modem

I have discontinued using a landline through NorthState Communication and since I am no longer using a landline, I would like to connect our home security system to the TWC Modem.


A telephone cable connected the alarm system into the outside phone service box.


Having the phone service through Specttrum, I want to connect the home security system directly into the Spectrum modem.  Since the alarm system has a phone line port and the Spectrum phone is using the phone line port, what is the best way to connect the security system to the modem?
