5.8.4 Multi-connections
Except for the configuration window for H1-datagram connections, all configuration windows
provide the facility to configure multi-connections. Multi-connections refer to multi-drop
connections. Here you may configure a second SSNR/ANR for an existing SSNR/ANR and its
TSAP or port. The respective and opposite job types are configured automatically. You may also
choose to let the multi-connection operate via a different channel.
You access the input window for multi-connections by means of the <Multi>button. Only the
descriptions of the input windows for multi-connections are different.
For example, the input window for a multi-TCP-connection has the following contents:

Parameters of a multi-connection
Frame offset (SSNR-offset)
You may specify a different frame offset for a multi-connection. The frame offset (SSNR-
offset) determines the frame from the start address that is used as communication job by the
current job. Frame offsets are normally only used in multi-processor systems with values
larger than zero.
Please use the following values when assigning frame offsets:
• Frame offset 0 for CPU 1
• Frame offset 1 for CPU 2
• Frame offset 2 for CPU 3
• Frame offset 3 for CPU 4
