BASIC CONCEPTS

System controller

The system controller contains the input subsystem and the control subsystem electronics.

The input subsystem provides interfacing capability (online, offline, Ethernet, and Dynamic Document Interface (for DEC, PC, MAC, and UNIX LAN connectivity) for a variety of input sources (host, magnetic tape, workstations, and graphic scanners).

Note: Your quarter-inch cartridge tape and floppy disk drives are not input sources for print jobs (refer to the ª4635 LPS hardware componentsº chapter).

The control subsystem performs all data handling, formatting, buffering, and operational control of the system. It also provides operator control through the LPS terminal or PC User Interface (UI). Refer to the ª4635 LPS hardware componentsº chapter for more information on system controller components and these subsystems.

LPS interfaces

The following LPS interfaces are available to connect a variety of input sources to the LPS:

Offline interface The offline interface permits input from a computer-prepared magnetic tape which is loaded onto the magnetic tape drive. The 9-track and 18-track magnetic tape drives are the optional offline interfaces available for the 4635 LPS. Refer to the ª4635 LPS hardware componentsº chapter for more information.

Online interface The online interface permits input from a channel-attached host computer.

Ethernet interface The Ethernet interface, using the host interface processor (HIP) task, permits input from workstations or graphic scanners on a shared or an unshared, but accessible, network.

DDI interface The Dynamic Document Interface (DDI) enables communication between a 4635 LPS and network via a shared disk mechanism over a SCSI bus. Refer to the Xerox Dynamic Document Interface Operator Guide for information regarding the DDI.

LPS system disk storage and memory

The system disks store the operating system software (OSS) as well as the system resources (fonts, forms, and graphics) that are to be loaded into memory for use during input processing. Refer to the ªLPS software componentsº chapter for more information on OSS.
