Remote connection: channel extender
For the channel extender connection, the printer is connected directly
to the channel extension device. The channel extender is then
connected to another channel extender through telecommunication
lines. Finally, the upstream channel extender is connected to the
System/370 or System/390 mainframe.
Channel extenders allow for long distance communication between
the host mainframe and the DocuPrint IPS printers. In addition,
channel extenders also have these characteristics:
• no spooling of jobs
• remote operator can control jobs via a 3270 session with the
host
• no resource storage.
