E. Remote Job Service

The RJS ("remote Job service") subsystem, was written by CCN to support remote batch terminals communicating over dial and leased lines. A remote batch terminal consists of a set of unit record devices (one or more card readers, printers, and punches) driven either by a hardwired controller or by a small CPU (e.g., IBM Model 20 or 1130). A remote RJS user enters OS/360 jobs, complete with JCL, into the remote reader; the jobs are spooled into the operating system and run in their turn, and the printed and/or punched output is returned to the remote terminal from which the jobs originated (unless the user or operator re-routes the output). The remote terminal may also include a console typewriter to be used by the remote operator to receive and send messages and to exert control over his terminal.
