Match iSeries system line description parameters for a remote iSeries system

You must coordinate communications configuration parameters between local and remote iSeries™ systems. These parameters are described in the following table. This table shows those prompts and parameters that must be coordinated when you specify line descriptions for the local and remote iSeries systems.
To configure a local iSeries server to a remote iSeries server:

See Connect one iSeries server to another iSeries server for an example of connecting one iSeries server to another iSeries server.
Use the following table for the line descriptions.

iSeries system Prompt iSeries Parameter Remote iSeries Parameter Notes

Local adapter address ADPTADR ADPTADR Adapter address of the local system (specified on the line description) must be matched at the remote system in the controller description ADPTADR parameter.
If the iSeries system uses an Ethernet line through an 8209 LAN Bridge, see "Appendix C: Local Area Network Addressing Considerations" in the Communications Configurationbook.
Insert network address in packets ADRINSERT ADRINSERT If X.25 DCE support is specified (X25DCE(*YES) or X25DCE(*NEG)), ADRINSERT(*YES) should be specified for both systems.
Data bits per character BITSCHAR BITSCHAR Values specified for each system must match.
Connection initiation CNNINIT CNNINIT If X.25 DCE support is specified (X25DCE(*YES)) for either system, CNNINIT(*LOCAL) should also be specified on that system's line description. The other system (with X25DCE(*NO) specified) should specify CNNINIT(*REMOTE) or CNNINIT(*WAIT).
For switched connections, both systems can also specify X25DCE(*NEG) to negotiate the Distributed Computing Environment (DCE) and data terminal equipment (DTE) roles and CNNINIT(*CALLER) to allow either system to initiate the connection by making the call.
See the X25DCE parameter for additional considerations.
Duplex DUPLEX DUPLEX Depending on the type of communications used, the values specified for the DUPLEX parameters may need to be coordinated.
Ethernet standard ETHSTD ETHSTD Values specified for each system must be coordinated. Both systems must specify the same standard (*ETHV2 or *IEEE8023) or at least one system must specify *ALL.
Exchange identifier EXCHID EXCHID Remote iSeries controller description EXCHID must match the local iSeries line description EXCHID. The first three digits of the exchange identifier, known as the block number, is 056 for the iSeries line. You can use the Work with Line Descriptions (WRKLIND) command to determine this value.
Logical channel entries LGLCHLE LGLCHLE If X.25 DCE support is specified (X25DCE(*YES) or X25DCE(*NEG)), logical channel types and channel numbers must be coordinated. See also the considerations for the X25DCE parameter.
Line speed LINESPEED LINESPEED For asynchronous lines, the line speeds specified for each system must match.
Modulus MODULUS MODULUS If X.25 DCE support is specified (X25DCE(*YES) or X25DCE(*NEG)), modulus values specified for each system must match.
The values specified for this parameter should match for all communications types.
Local network address NETADR CNNNBR For switched virtual circuits (SVCs), the NETADR parameter on the local system line description must match the CNNNBR parameter on the controller description for the remote system.
NRZI data encoding NRZI NRZI Values specified for each system must match (*YES or *NO).
Data link role ROLE ROLE The value specified for the local system line description ROLE parameter should match the controller description ROLE parameter specified at the remote system.
Number of stop bits STOPBITS STOPBITS Values specified for each system must match.
Switched connection type SWTCNN SWTCNN Values specified for each system must be compatible. (*DIAL or *ANS must not be specified for both systems.)
X.25 DCE support X25DCE X25DCE If X.25 DCE support is used (X25DCE(*YES)), only one of the iSeries line descriptions should specify *YES. The system specifying X25DCE(*YES) should also specify CNNINIT(*LOCAL); the other iSeries server should specify X25DCE(*NO) and CNNINIT(*REMOTE) or CNNINIT(*WAIT).
For switched connections, both systems can also specify X25DCE(*NEG) to negotiate the DCE and DTE roles, and CNNINIT(*CALLER) to allow either system to initiate the connection by making the call.
