2 must be present in the host processor in order to initialize the remote 4381
Processor. The remote 4381 Processor must use an MVS operating system. If
continued control of the jobs in the remote 4381 Processor via a standard
communications network is required, the remote 4381 must also be running
under MVS/370 or MVS/XA with MVS/OCCF and MVS/NCCF.
For a VM/370 environment, the VM/Pass-Through Facility as of Release 2 is
required in the host processor to initiate remote 4381 Processor operation.
The remote 4381 Processor must use VM/370. If continued control of the
jobs operating in the remote 4381 Processor is desired, VM/SP as of Release 2
with the Programmable Operator Facility is required in the remote 4381
Processor.

Figure 15. Dialup of a remote 4381 Processor via a host processor emulating a 3275 display
When ROCF support is present in a 4381 support processor, an ROCF Installation
display is provided. This display allows an operator at the 4381 Processor site to
enable and disable ROCF mode. When ROCF is enabled, the ROCF function is
automatically activated during each IML of the support processor in the 4381
Processor. This activation permits remote dialup of the 4381 Processor. When
ROCF mode is disabled, the ROCF function is not activated and a remote dialup
of the 4381 Processor is not possible.
Password protection is supported to prevent unauthorized access to the remote
4381 Processor. When a dialup of a remote 4381 Processor occurs, the first
display sent to the host location is the ROCF Password display. The operator at
the host location must enter the correct password within a certain time interval or
the telephone link between the 4381 Processor and host location is automatically
disconnected. If the password is correct, the next display sent to the host location
is the General Selection display. At this time, the host operator can select
functions to display hardware information, IML or IPL the system, or return to
operating system displays.
