Device High (Channel Address)
For SNA:
This is the last channel address LINCS will occupy on the channel for this CU.
The Device High must be a value such that (Device Low + Number of Host Circuits + Number
of Gateway Circuits - 1) is less than or equal to hexadecimal x’FF’, which is the highest
channel address available on the channel.
You should make a record of the channel addresses allocated on the Channel/SNA panel.
They will be used again to specify which channel addresses will be assigned to which host
circuits and gateway circuits on the 3270 Host Circuits and Gateway Circuits panels.
For CNC:
This is the last channel address LINCS will occupy on the channel through this CU. Since
each LAN adapter associated with the IP Channel Bridge feature requires a single consecutive
pair of addresses, the Device High should be an odd-valued number (01, 03, 05, etc.).
For Non-SNA:
The Device High corresponds to the last device session channel address. (Device High –
Device Low + 1) must be less than or equal to x’20' hex (32 decimal or 20 hex is the maximum
number of non-SNA device sessions that can be configured, per CU).
The Device High must also be less than or equal to x’FF’. If more than 32 non-SNA device
sessions are required, an additional CU must be defined for each group of 32 non-SNA device
sessions.
LPAR Number
This is the number assigned to the LPAR that would be found in the RESOURCE macro of
the host gen.
Source Link Address
This value corresponds to the port number on the ESCON switch that connects back to the
host CPU, when an ESCON switch is being used. If no ESCON switch is being used, then
this value should be left as ‘FF’ or can be set to ‘01’ (either value should work).
CU Number
This is the CUADD value that has been defined in the host gen, in the CNTLUNIT macro
corresponding to this CU.
