(GA24-3949). This manual also identifies operational similarities and differences
for 4381and4341 Processors and enhancements made for 4381 Processors.
40:15 Remote Operator Console Facility (ROCF)
ROCF support in the support processor of a remote 4381 Processor provides the
ability to:
•
Dial up and control a remote powered-on 4381 Processor from a 3275 Model 2
Display Terminal at a host location, as shown in Figure 14. The operator at
the host location can perform all the supported 4381 manual control functions
(IPL, instruction processor function IML, display, alter, etc.) using the 3275
display that can be performed using a local console except for a power-on of
the 4381 system and functions that require manual operation at the 4381 site
(support processor IML, diskette change, for example). A DOS/VSE, VSl,
MVS/370, MVS/XA, or VM/370 operating system can be IPLed in the 4381
Processor via a remote 3275 display.

Once the 4381 Processor is operating, the operator at the 3275 display can
disconnect the 3275 from the RSF port in the 4381 Processor. The 4381
support processor will then enable autoanswer mode so that a remote dialup
via a 3275 is again possible. If continued control of jobs in the remote 4381
Processor is desired, a normal teleprocessing network (involving 270X and/ or
370X controllers) should be used.
•
Dial up and control a remote powered-on 4381 Processor from a 327X display
connected to a host processor that is emulating a 3275 display, as shown in
Figure 15 on page 92. The 327X display can be used to perform the same
manual functions as can a stand-alone 3275 at the host location discussed
above. Once the 4381 Processor is operating, the 327X can be disconnected
from the ROCF link and a standard communication network can be established
if continued control of the jobs in the remote 4381 Processor is required. The
host processor used to dial up and control the jobs in the remote 4381
Processor must be running under the control of MVS/370, MVS/XA, or
VM/370.
For an MVS environment, MVS/SP-JES2 Version 1 as of Release 3.2,
