Datastreams A front end processor is required in this configuration to connect
TCP/IP to XNS. The front end processor also converts PostScript
datastreams to .IMG files, which is necessary if the application
software being used produces output in PostScript. If the
application software produces output in Interpress, the front end
processor connects TCP/IP to XNS and passes the Interpress
datastreams through without further conversion.
Other workstations
Workstations other than the IBM PC, Macintosh, and Sun may
also be connected to the LPS through a LAN. The connectivity
products needed depend upon the type of network used, the
communication protocols used on that network, and the
datastreams generated by the application software in use.
Ethernet interface Several types of workstations now have Ethernet compatibility.
An Ethernet card is required for each compatible workstation you
wish to connect to the LPS.
If the workstation uses TCP/IP protocol on Ethernet, a front end
processor is required to connect TCP/IP to XNS. A front end
processor is also necessary if the application software used
produces a datastream other than Interpress or LCDS.
Refer to Figure 4-7 for an example of an Ethernet LAN interface.
Other network interfaces If your workstations use a LAN other than Ethernet, a
communication module is necessary to convert to Ethernet. This
conversion usually produces TCP/IP on Ethernet rather than XNS
on Ethernet.
A bridge or front end processor is required to convert TCP/IP to
XNS. The front end processor is also necessary if the application
software used produces a datastream other than Interpress or
LCDS.
Refer to Figure 4-8 for an example of an interface involving a
non-Ethernet LAN.
