Backup Communications Configuration
When you configure a channel for backup communication, you must enter
the following parameters:
Parameter Description
Resident number identifies the system being configured on the channel. The resident number
must be different from the partner number and selected from numbers 81
through 89.
Partner number identifies the other system on the channel. The partner number must differ
from the resident number and selected from number 81 through 89.
Input file identifies the file that receives data from the partner. The input file must be in
the input image section of the data table. If you do not make a selection, the
file defaults to input file 1. This file must be large enough to store the data from
the partner system's output file. Otherwise, the processor sets the backup
communication minor fault bit.
Output file identifies the file that sends data to the partner. The output file must be in the
output image section of the data table. If you do not make a selection, the file
