Match iSeries system parameters for a 3174 controller

You must match the iSeries™ configuration parameters with the configuration questions and sequence numbers to configure the 3174 controller. These parameters are described in the following table.

For more information about configuring the 3174 controllers, see these books:

To configure the iSeries server to a 3174 controller:

iSeries Prompt iSeries Parameter 3174 Configuration Questions Notes
LAN remote adapter address1 ADPTADR 084, 106 Ethernet Address

If the iSeries system uses an Ethernet line to connect to the 3174 controller, use table C-3 on page C-4 in "Appendix C: Local Area Network Addressing Considerations" of the Communications Configuration Link to PDF book to convert the value specified for question 084. Specify the converted address for the ADPTADR parameter on the CRTCTLRWS or CRTCTLAPPC command.

Token-Ring Network Address of the 3174

If the iSeries server uses a Token-Ring network line to connect to the 3174 controller, values specified for question 106 and for the ADPTADR parameter on the CRTCTLRWS or CRTCTLAPPC command must match.

If the iSeries server uses an Ethernet line through an 8209 LAN Bridge, see "Appendix C: Local Area Network Addressing Considerations" in the Communications Configuration book.
Local adapter address ADPTADR 107 Token-Ring Network Address of the Gateway

If the iSeries server uses a Token-Ring network line to connect to the 3174 controller, values specified for question 107 and for the ADPTADR parameter on the CRTLINTRN command must match.

If the iSeries server uses an Ethernet line through an 8209 LAN Bridge, see "Appendix C: Local Area Network Addressing Considerations" in the the Communications Configuration Link to PDF book, for information about specifying the ADPTADR parameter on the CRTLINETH command.
Connection number CNNNBR 423 Host DTE Address (HNAD)

For X.25 lines, the numbers specified on the CRTLINX25 command and in question 423 must match.
368 X.21 Switched Short-Hold Mode Dial Number

For X.21 short-hold mode connections, the numbers specified on the CRTCTLRWS command and in question 368 must match.
424 3174 DTE Address

For X.25 SVCs, the connection number specified on the CRTCTLRWS command and in question 424 must match.
Destination service access point DSAP 940 Ring Address Assignment

The value specified for the DSAP parameter on the CRTCTLRWS command must match the SAP@ specified for the 3174 on the Ring Address Assignment display. Used for token-ring only.
Exchange identifier EXCHID 215 Physical Unit Identification

For switched connections, the 5-digit hexadecimal value specified for question 215 must match the last 5 digits of the exchange identifier specified on the CRTCTLRWS command.
Link type LINKTYPE 101 Host Attachment (3174)

Values specified on the CRTCTLRWS command and for question 101 must match as follows:

  • LINKTYPE(*SDLC), 101 = 2
  • LINKTYPE(*X25), 101 = 3
  • LINKTYPE(*LAN), 101 = 7 (token ring)
  • LINKTYPE(*LAN), 101 = 8 (Ethernet)
Modem data rate select MODEMRATE 318 Full- or Half-Speed Transmission

The values specified for the MODEMRATE parameter on the CRTLINSDLC and CRTLINX25 commands must match question 318 as follows:

  • If MODEMRATE(*FULL), 318 = 0
  • If MODEMRATE(*HALF), 318 = 1
Local network address NETADR 423 Host DTE Address (HNAD)

For X.25 SVCs, the network address specified on the CRTLINX25 command and in question 423 must match.
NRZI data encoding NRZI 313 NRZ or NRZI Encoding

For SDLC lines only, the values specified on the CRTLINSDLC command and in question 313 must match as follows:

  • If NRZI(*NO), 313 = 0
  • If NRZI(*YES), 313 = 1
Source service access point SSAP 940 Ring Address Assignment

The value specified for the SSAP parameter on the CRTCTLRWS command must match the SAP@ associated with the Ring@ (adapter address) of the iSeries system on the Ring Address Assignment display. Used for token-ring only.
Short-hold mode SHM 367 X.21 Switched Short-Hold Mode

Values specified on the CRTCTLRWS command and in question 367 match as follows:

  • If SHM(*NO), 367 = 0
  • If SHM(*YES), 367 = 2
Station address STNADR 104 Control Unit Address

Value specified for question 104 must match the STNADR specified on the CRTCTLRWS command.
Switched connection SWITCHED 317 Telecommunication Facilities

Values specified on the CRTLINSDLC command and in question 317 match as follows:

  • If SWITCHED(*NO), 317 = 0
  • If SWITCHED(*YES), 317 = 1
Note:
If you are using a 3174 Model 1L Gateway to connect an iSeries server to a host server on a Token-Ring, the value specified for item 900 (Token-Ring Network Address of the Gateway) must match the value specified for the ADPTADR parameter on the CRTCTLHOST command.
