Configuring Ethernet Connections on the AS/400 System
__ 2. Type WRKLIND and display the line description for your active line. Make note of the Local Adapter Address and NRZI encoding
__ a. AS/400 Node Address (Local Adapter Address) _____________________
__ b. NRZI Data Encoding (Y or N) ____________
__ 3. While you are configuring your AS/400 for SDLC, write down the following values:
__ a. Exchange Identifier (Block ID and Physical Unit on the PC) __________________________
__ b. Local Station Address __________________________________
__ c. Controller description (name you gave your PC) _________________________
__ d. Station address ______________________________
__ e. Switched line list ____________________________
__ f. Initial connection information (does the PC call the AS/400 (*ANS) or the AS/400 call the PC (*DIAL) or is it a leased line?)
__ g. Connection number (if AS/400 calls the PC) __________________
Client Access supports SDLC for non-switched (such as leased) and switched (dial) connections. For switched connections, V.25bis automatic dial, manual dial, and DTR (stored number) dial are supported.
Modem Notes:
Look in the compatibility section of the Client Access for Windows 95/NT web page for information about SDLC modem testing.

v IBM 7855
– Reset to the factory configuration and change the DSR to always on. Information on performing the factory reset is detailed on page 6-12 of the IBM7855-10 Guide to Operations manual. Information on setting DSR to always on is detailed on page 6-23.

v IBM 7857
– Reset to factory configuration 3 and set C107/C109 to C109 Ctrl. Information on performing the factory reset is detailed on page 53 of the IBM7857 Guide to Operations manual.
v IBM 7852–400
– Reset to the factory configuration and change DSR to always on (switch 15 down).
v IBM 7858
– Reset to the factory configuration preset #3 and change DSR to always on (switch 15 down).
To configure an SDLC connection by usingCFGPCS:
__ 1. TypeGO CFGPCSat the AS/400 command prompt, then select Option 4,
Synchronous data link control (SDLC). The display shown in Figure 58 appears.
This display shows you the name of the line description. Accept the default and press the Enter key.
__ 2. If this is the first time you are adding a user, the display that is shown
inFigure 59 appears. If this is not the first time that you are adding a user, go to step 4 on page 85.
On this display, you need to specify the connection type to be used for this line.
The possible values are:
v *NONSWTPP (Nonswitched point-to-point line). This is for leased lines.
v *SWTPP (Switched point-to-point line). This is for dial-up lines.
Create SDLC Connection Type choices, press Enter.

v *MP (Multipoint). Leased not switched line.
In the NRZI data encoding field, specify whether your SDLC hardware uses non-return-to-zero (inverted) (NRZI) data encoding. The setting you use on the AS/400 system must match the setting you choose on the PC. Accept the default (*YES), unless you have applications or modems that require a *NO setting. For example, if you are using a line splitter or an IBM 7852–400 modem, specify
*No.
__ 3. Press the Enter key to continue.
__ 4. Add SDLC connection information for each user.
You must repeat this step for each PC connection that is using SDLC. Figure 60 lets you create a controller for the line that is shown at the top of the display.
Fill in the prompts for each PC connection that you want to make. The
parameters are explained below. When done with each, press Enter to add more or finish.
Controller description
This associates a controller description with the PC. This is the name by which the PC is known on the network. To make this easy to remember, enter the user ID of the PC user.
Station address
Every PC that is attached to AS/400 through a single SDLC line needs a unique station address. Assign an address for this PC.
Switched line list
This prompt allows you to specify if there are other switched lines this controller will attach to. If you specify Y, up to 10 line description names may be entered. The line descriptions must already be created.
Initial connection
This prompt appears only if you specified the line type as switched, and allows you to specify whether the AS/400 system or the PC initiates the
communications. Select *ANS if the PC initiates the call, or *DIAL if the AS/400 system initiates the call. If you do not know which system initiates the call, accept the default of *ANS.
Add PC to SDLC Connection

Chapter 11. Configuring SNA SDLC & AutoSync Connections on the AS/400 System 85
Fill in the Activate role as Caller or Called, to match the role of the PC.
Connection number
This prompt appears only if you specified *DIAL on a switched line. This is the telephone number that the host system should dial if it wants to initiate communications with the PC.
Vary on line and controller
This prompt appears only if you specified the line type as nonswitched. This prompt allows you to specify if you want the controller to vary on when it is created. Accept the default of Y.
Text Type any description you want for the controller.
Note: If you are using a line type of *SWTPP, you need to vary on the controller. Type WRKCFGSTS *LIN on an AS/400 command line, find your controller and enter 1 next to the line description to vary it on.
You are now finished configuring SNA SDLC Connections to the AS/400 system. Return to the checklist in “Chapter 2. Setup Checklist” on page 15.
