XEROX 4050/4090/4450/4650 LPS PRODUCT REFERENCE
A DEC VAX/VMS platform can use the XPMF-VMS option to
connect to an LPS through a DEC communications interface. For
a local connection, the Xerox-supplied modem eliminator may be
used to provide a point-to-point communications link. You can
use modems to create a remote connection.
The XPMF software is installed on the host to generate DJDEs
from the DEC DCL PRINT command and accommodate the
physical linkage using the DEC DDCMP protocol.
Reference Refer to the XPMF-VMS product literature for more details on this
interface option.
Figure 4-4.
Datastreams In this configuration, application output is in ASCII text plus DJDE
format. No datastream conversion is required. A front end
processor is not applicable.
A DEC VAX/VMS mainframe is connected to an LPS through an
Ethernet LAN as shown in figure 4-5. Multiple solutions are
present for this environment.
SPUR System 534: The SPUR System 534, available from the
Xerox Connection, provides network connection. It should be
noted that any VAX system utilizing TCP/IP in the VMS
environment requires the DEC TCP/IP Services for OpenVMS (or
equivalent), if it is not already present.
Xerox XNS 5.0 for VMS: If the Xerox XNS for 5.0 for the VMS
software package is used, no communications protocol
conversion is required. If XNS 5.0 is not used, then a bridge that
provides connectivity between the VAX Ethernet TCP/IP or
DECnet protocol and the selected Xerox interface is required.
Note: XNS 5.0 for VMS is limited to text printing only.
Entire 400/600: The Entire FIBRE 400/600 front end processor
serves as a bridge for TCP/IP.
FunAsset TNxxxx: In Rank Xerox, the FunAsset TNxxxx series
provides network connectivity through a DECserver 250, or
equivalent. The FunAsset interface is also capable of providing a
local or remote communications interface.
