LINCS Configuration

For Channel/SNA, the PU address must fall within the Lower Limit and Upper Limit Channel
Address range specified on the Channel/SNA Line Options panel. For Channel/CTC, the
address entered implies the first of a consecutive two-address pair, and must be an even
address. Both the selected address and implied address must fall within the Lower Limit and
Upper Limit Channel Address range specified on the Channel/SNA Line Options panel.
Remote LAN Address
This is the LAN address of the upstream node. Remote is always from the viewpoint of the
LINCS node.
Enter a 12-digit hex number for the LAN address. Make sure that the LAN address and SAP
combination you enter is unique for this line.
Remote SAP
Enter a 2-digit hex SAP address for the upstream node of this circuit. Valid SAP addresses are
multiples of 4, ranging from 4 to EC (hex).
Remote IP Address
Enter a 12-digit decimal number for the IP address of the remote host. The IP address should
be a uniquely assigned value given to the remote device by the network administrator. It
needs to follow the guidelines of any IP address assignment.
Secondary Station Address
Enter a 2-digit hex number, provided by the host systems programmer. The secondary station
address is the X.25 term for SNA PU address, as configured at the SNA host. Make sure that
the PU address you enter is unique for this line.
X.25 can also be used to gateway to downstream nodes, so secondary station address also
appears when X.25 is used for the downstream connection.
Downstream Connection (DSC)
Remote Data Link ID
A Remote Data Link ID field is used in conjunction with the IP Address field to uniquely
identify incoming TCP/IP frames from other host circuits or gateway circuits. This address
combination must be unique throughout the network.
The data link ID fields must be entered in the canonical format for Token Ring, and non-
canonical format for Ethernet, of a LAN Address and SAP.
If the downstream connection is configured for LLC, the Data Link ID will be taken from the
downstream’s Remote LAN Address and SAP fields. If the downstream connection is configured
for TCP/IP, the Data Link ID will be taken from the downstream’s Remote Data Link ID.
The Remote IP address indicates the remote device, and the Remote Data Link ID identifies
the specific circuit on the remote device. The Remote Data Link ID defined on the upstream
gateway connection must match the Remote Data Link ID defined on the downstream
connection of the corresponding upstream node’s gateway circuit.
