Switches in the WAN provide connectivity for voice, data, and video communication. Modems include interface voice-grade services, channel service units/digital service units (CSU/DSUs) that interface T1/E1 services, and Terminal Adapters/Network Termination 1 (TA/NT1s) that interface Integrated Services Digital Network (ISDN) services. Communication servers concentrate dial-in and dial-out user communication. WAN Standards WAN physical layer protocols describe how to provide electrical, mechanical, operational, and functional connections for WAN services. WAN data link protocols describe how frames are carried between systems on a single data link WAN standards are defined and managed by a number of recognized authorities, including the following agencies: International Telecommunication Union-Telecommunication Standardization Sector (ITU-T), formerly the Consultative Committee for International Telegraph and Telephone (CCITT) International Organization for Standardization (ISO) Internet Engineering Task Force (IETF) .
