A Typical Modem Connection
The devices involved in a modem connection belong to one of two groups: data terminal equipment (DTE) or data communications equipment (DCE).
NOTE
Interestingly, the Electronic Industries Association (EIA) defines DCE as data communications equipment. However, the International Telecommunication Union-Telecommunications Standards Sector (ITU-TSS, or ITU-T) defines DCE as data circuit-terminating equipment.
Examples of the DTE devices are
PCs
Routers
Mainframe computers
DCE devices include
Modems
Channel service units/data service units (CSUs/DSUs)
