Attributes for SNAX/XF and SNAX/APN

SNAX/XF and SNAX/APN Configuration and Management Manual—425836-006

14-26

INTERFACE

For line type 58,5 (SDLC), INTERFACE defines the physical interface between the

controller and the modem or modem eliminator.

The following values are valid for this attribute in an ADD or ALTER command:

If a value is specified in the SCF ADD DEVICE command, that value is the default. If

no value is specified, the PSX1TS Profile default value is RS232. Use RS232 unless

V25 or X21 are employed.

For X.21, only leased line connections are supported; switched line connections are

not supported.

For X.25 and Token-Ring lines, this attribute cannot be set in the ADD or ALTER

command. However, the following values are automatically set by SNAX/XF and

appear in the detailed INFO LINE display:

IOPAGES

IOPAGES specifies the number of pages in extended memory to allocate for I/O

buffers and the poll list. Valid values are from 0 through 64 pages. The recommended

value for this attribute is 0. If 0 is specified, SNAX/XF calculates the appropriate value.

If IOPAGES is not specified using an SCF ADD or ALTER command, SNAX/XF

calculates a value. For line type 58,5 (SDLC), this value is based on the values of the

RECSIZE, WINDOW, and MAXPUS attributes.

Default: RS232

Value: RS232 | RS422 | V25 | X21| X25 (INFO only) | TR (INFO only)

Objects: LINE

RS232 specifies that the line uses the RS-232 electrical interface. This value has

no functional meaning for the SWAN concentrator.

RS422 specifies that the line uses the RS-422 electrical interface. This value has

no functional meaning for the SWAN concentrator.

V25 Specifies that the line uses the V.25 bis data-communications protocol.

X21 specifies that the line uses the X.21 electrical interface.

X25 specifies that the line uses the X.25 protocol through X25AM. SNAX/APN

does not support X.25 SVCs.

TR specifies that the line uses the Token-Ring protocol through TLAM.

Default: See following description

Value: 0 - 64

Objects: LINE
