NETWORK CONNECTIVITY
IBM PC and PC-compatible workstations
PCs can be connected to an LPS with a network connection
(Ethernet or other) or in an online configuration using third-party
interface hardware and software.
Ethernet interface
A PC may be connected to an LPS through an Ethernet Local
Area Network.
Communication protocols Each PC on the Ethernet LAN requires its own Ethernet card. The
Ethernet TCP/IP print jobs are converted to Ethernet XNS print
jobs by the Entire FIBRE 400/600 front end.
A combination of Ethernet card and the Xerox XNS PC Plus 2.0
software package allows a PC to produce XNS protocol on
Ethernet. This configuration does not require a front end if it is
used with software applications that produce LCDS or Interpress
datastreams.

Datastreams Most of the application software running on a PC in this
configuration produces PostScript datastreams. When using
PostScript applications, a front end is required to convert the
PostScript output.
Other network interfaces
PCs may be connected to networks other than Ethernet as
shown in figure 4-8, including a token ring.
Communication protocols Non-Ethernet networks require a communication module that can
convert to Ethernet. Generally, this type of communication
module converts the original network protocol to TCP/IP
protocol on Ethernet. This requires a front end that converts
TCP/IP to XNS.
