or
The Entire FIBRE front end also functions as a bridge for print
jobs. FIBRE accepts TCP/IP communication protocol on Ethernet,
converts the print job from PostScript to .IMG files, and then
sends the converted job out through the XNS network on
Ethernet. If the PostScript application is being run on a platform
that does not use either Ethernet or the TCP/IP protocol, then an
additional gateway is necessary to convert to TCP/IP on Ethernet
before the data stream goes to the front end.
Connectivity options for IBM and compatible mainframes
To determine the appropriate connectivity option for your IBM
mainframe environment, you need to take into account the
interface option you use and the data streams to be output by
your application software.
Interface options
IBM and IBM-compatible mainframes can be connected to a
4890 through an online direct interface, a remote interface, or a
network.
Online direct interface
The IBM direct interface, also called a channel interface, uses the
IBM 3211 or 4245 protocols as shown in figure 4-8.
