AFP SUMMARY
IPS SOLUTIONS GUIDE 2-11
AS/400 remote connection
AS/400 does not use a direct Bus & Tag connection. Instead, you
must set up a remote PSF/2, PSF for AIX, or BARR/AFP connection.
An AS/400 channel connection requires either BARR/AFP or a PS/2.
BARR/AFP uses an LU 6.2 connection to carry real-time, bi-
directional traffic from the host to IPDS Group 3 printers. The LU6.2
connection can be either SDLC or Token Ring. Because the IPDS
protocol allows the printer to feed its status back to the host in real
time, BARR/AFP does not spool the AFP data. Instead, jobs are
printed as they are received from the host.
TCP/IP connection: Ethernet
For the Ethernet TCP/IP connection, you must have an Ethernet card
installed inside the AS/400. A router directs the jobs being run on the
Ethernet to the appropriate device.
