What type of cable and connectors are used to connect a modem to a phone port?

To connect a modem to a phone port, a standard telephone cable, often referred to as an RJ-11 cable, is used. The connectors on each end of the cable are RJ-11 connectors, which fit into the phone port on the wall and the modem. This type of connection is typically used for DSL modems that utilize existing telephone lines for internet service.
