SDLC Implementation Notes
Keep the following implementation notes in mind when you configure SDLC
services.
Link Stations
With DLSw, you can configure SDLC as a primary or secondary link station only.
With APPN, you can configure primary, secondary, and negotiable link stations.
You set up SDLC link stations as follows:
• Primary link stations -- configure the adjacent link station’s parameters.
• Secondary link stations -- configure the station’s own link station parameters.
• Negotiable link stations -- configure the station’s own link station, as well as a
potential adjacent link station.
Refer to Chapter 4 for information on configuring SDLC link stations.
Synchronous Line Parameters
When you add SDLC to a synchronous line, Site Manager opens the SDLC Line
Parameters window, and you can then edit the following parameters:
• Clock Source
• Internal Clock Speed
• Sync Line Coding
• Cable Type
• RTS Enable
