#+title: modem
A digital subscriber line ([[id:52ff159a-87dc-421c-87c2-803416acd7ae][DSL]]) modem is a device used to connect a computer or [[id:d2ff2e45-e1de-4cca-9b59-dfc3ee6afa6f][router]] to a telephone line which provides the digital subscriber line (DSL) service for connection to the Internet, which is often called DSL broadband. The modem connects to a single computer or router, through an [[id:c5a27aff-1c9c-4355-a793-202d71388930][ethernet]] [[id:f4bb4857-2112-4e10-a22e-6da1436ce7b7][ports]], USB port, or is installed in a computer PCI slot.
The more common DSL router is a standalone device that combines the function of a DSL modem and a router, and can connect multiple computers through multiple Ethernet ports or an integral wireless access point ([[id:ccab5008-e48e-413d-bcb5-c6771fa77a3d][WAP]]). Also called a residential gateway, a DSL router usually manages the connection and sharing of the DSL service in a home or small office network.
Different DSL routers and modems support different DSL technology variants: VDSL, SDSL, and ADSL.
