The system is administered through an assortment of teletypewriter "Channels" (also called the system console) such as the TEST channel and Maintenance channel. Typically provisioning is done either through a command line interface (CLI) called RCV:APPTEXT, or through the menu-driven RCV:MENU,APPRC program. RCV stands for Recent Change/Verification, and can be accessed through Switching Control Center System.
