IBM System/38
This section describes the generation parameters and restrictions that apply to the
System/38.
System/38 Generation Parameters
The following sections describe the settings recommend or required in the System/38
generation to support the 3708.
• Line Description Name
It is recommended that the line description name (LIND) associated with the
System/38's line description definition match the name defined in the SNA Line
Network Name parameter of the 3708 configuration. This is not required, but
because the 3708 uses the SNA Line Network Name in its alerts to the host,
network management is easier if the two names are the same, related, or
equivalent.
• Line TYPE
The line type defined in the System/38's line description definition must be
*SDLCP.
• NONRTNZ
Both NONRTNZ
=
YES and NONRTNZ=NO may be defined in the
System/38's line definition description. If NONRTNZ = YES is defined, NRZI
data encoding must be set to I in the 3708's configuration. IfNONRTNZ=NO
is defined, NRZI data encoding must be set to O.
• Control Unit Description Name
It is recommended that the control unit description (CUD) name associated with
the System/38's control unit description definition match the name defined in the
3708's SNA PU Network Name. This is not required, but because the 3708 uses
the SNA PU Network Name in its alerts to the host, network management is
easier if the two names are the same, related, or equivalent.
• Control Unit Type
Control unit type must be defined as TYPE
=
3274.
• MODEL
MODEL must be defined as *NONE is the System/38's device description
definition.
• Control Unit Address
The first 2 bytes of the control unit address (CTLADR) parameter in the
System/38's control unit description must be equivalent to the station address
defined in the 3708's configuration. The second 2 bytes of the CTLADR must
be equivalent to the line number defined in the System/38's line description
definition (LINNBR).
• Device Description Name
Device description (DEVD) name associated with the System/38's device
description definition must match the name defined in the 3708's SNA LU
Network Name. This is not required, but because the 3708 uses the SNA LU
Network Name in its alerts to the host, network management is easier if the two
names are the same, related, or equivalent.
