number CNNNBR 411 3274 DTE Address
For X.25 SVCs, the connection number specified on the
CRTCTLRWS command and in sequence number 411 must
match.
Exchange
identifier EXCHID 215 Physical Unit Identification
For switched connections, the 5-digit hexadecimal value specified
for sequence number 215 must match the last 5 digits of the
exchange identifier specified on the CRTCTLRWS command.
X.25 link
protocol LINKPCL 403 Logical Link Control
For X.25 connections, values specified must match. Specify
LINKPCL(*QLLC) on the CRTCTLRWS command; specify
1
(QLLC) for sequence number 403.
Link type LINKTYPE 331 BSC/SDLC/X.25 Protocol
Values specified on the CRTCTLRWS command and in
sequence number 331 must match as follows:
v
If LINKTYPE(*SDLC), 331 = 1
v
If LINKTYPE(*X25), 331 = 2
Local network
address NETADR 410 Host DTE Address (HNAD)
For X.25 SVCs, the network address specified on the
CRTLINX25 command and in sequence number 410 must match.
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 sequence
number 318 as follows:
v
If MODEMRATE(*FULL), 318 = 0
v
If MODEMRATE(*HALF), 318 = 1
NRZI data
encoding NRZI 313 NRZ or NRZI Encoding
For SDLC lines only, the values specified must match as follows:
v
If NRZI(*NO), 313 = 0
v
If NRZI(*YES), 313 = 1
Short-hold
mode SHM 362 X.21 Switched Options
If SHM(*YES) is specified on the CRTCTLRWS command, digit 7
or 8 of question 362 must be set to 1. (For example, xxxxxx10
indicates that the DCE is supported for direct calls.)
Station address STNADR 302 Control Unit Address
Value specified for item 302 must match that specified on the
CRTCTLRWS command.
Example: Connecting an AS/400 to a 3174 control unit
Configuration parameters must be coordinated when you connect an AS/400 system to a 3174 controller.
