You use the OEM interface for System Network Architecture and
Synchronous Data Link Control (SNA and SDLC) protocol and for
Binary Synchronous Communications (BSC) protocol. The 871-
CM and the LPS resident OEM interface work together to allow
ASCII and EBCDIC data transmission to the LPS, allowing the LPS
to print jobs from a remote IBM-compatible host computer
system. The 871-CM uses a telephone modem to eliminate the
need for a channel-attached extender unit.
Reference Refer to the Xerox 4050/4090/4450/4650 LPS System
Administration Guide and to the Xerox 871-CM System Guide for
more information on SNA, SDLC, and BSC communications.
You use the DEC interface for communication in VAX/VMS DEC
Data Communications Message Protocol (DDCMP)
environments. This interface allows communication between a
DEC VAX/VMS system and an LPS through cable or modem
connections, using Host Interface Processor (HIP) tasks. The
DEC interface supports all UNIBUS, VAX-BI, or Q-Bus based DEC
processors.
You use the Ethernet interface for devices connected to the
network. Ethernet is the Xerox Local Area Network (LAN) which
allows data to be transmitted by cable from one device to
another. Using the Ethernet, your LPS can receive and print
documents from other network devices such as the following:
• Ethernet workstations, such as the Xerox 6085 can transfer
Interpress files to the LPS and can invoke LPS-stored forms
and graphics for printing.
• Ethernet graphic scanners, such as the 7650 Pro Imager and
the 150 Graphic Input Station (GIS), can transfer scanned
graphic data, including line art and continuous tone images,
to the LPS. The LPS must have GHO/GVG to receive
digitized graphics.
Make sure you select both the communications interface and the
Ethernet interface at system generation if you are using Ethernet
communications.
IBM and IBM-compatible mainframes can be connected to an LPS
through an online direct interface, a remote interface, or a
network.
The IBM direct interface, also called a channel interface, uses the
IBM 3211 or 4245 protocols as shown in figure 4-1.
