The alternate console can be:
An IBM 3151 Display Station running in native mode
An IBM 3161 Display Station running in IBM 3101 emulation mode
An IBM 3163 Display Station running in IBM 3101 emulation mode
A PS/2 (models 50 and above) with OS/2 extended edition running in IBM 3101
emulation mode
An IBM 3727 Operator Console (a keyboard overlay is provided with the
controller)
Any equipment providing equivalent functions.
Console Sharing
In multiple-controller installations, instead of having one operator console per
controller, it is possible to share one console between several IBM communication
controllers. In this case, the shared console is attached to an IBM 7427 Console
Switching Unit. The IBM 7427 is an RPQ.
A maximum of four IBM communication controllers can share a local console.
In this case, the shared console must be at a maximum distance of 7 m (23 ft.)
from any communication controller.
A maximum of six IBM communication controllers can share an alternate
console.
Remote Support Facility
The remote support facility (RSF) is connected to IBM RETAIN and provides IBM
maintenance assistance when requested. The RSF is attached to the 3745 over
the public switched network via a DCE.
|
The MOSS-to-RETAIN connection is made with a BSC protocol at 1200/2400 bps
|
(V.22/V.22 bis interface, or V.23 HD 1200 bps, depending on the country), via a
|
duplex external modem with the auto-answer feature.
|
In selected countries an RSF modem is supplied with the controller.
