DCE (Data Communications Equipment)

Also known as data circuit terminating equipment

(DCTE). Equipment that interfaces data terminal equipment (DTE) to a wide area network (WAN), resolving any issues of incompatibility. Incompatibility issues can include signal format (digital versus analog), voltage level, signaling speed, and bit density. DCE includes modems, digital service units (DSUs), channel service units (CSUs), and front-end processors (FEPs). See also analog, bit density, CSU, digital, DSU, DTE, FEP, modem, signaling speed, voltage, and WAN.
