Dependencies

ANSI point code value 000-000-000 and ITU-International point code value 0-000-0 are not allowed.

The specified screening reference (sr ) must be in the allowed DPC entity set.

Any specified ni parameter must already exist in the allowed DPC entity for the screening reference.

The Spare Point Code Support feature must be enabled before the pcst parameter can be specified.

The spare point code subtype prefix (s-) is not supported for ANSI point codes (parameters ni, nc, ncm) or for 24-bit ITU national point codes (parameters msa, ssa, sp) or for 16-bit ITU national point codes (parameters un, sna, mna). The pcst parameter cannot be specified for ANSI, ITU-N16 or ITU-N24 point codes.

If the pcst parameter is specified, point codes with the specified subtype prefix (no prefix or s- ) must exist in the database.

If the ni=* parameter is specified, then the nc=* and ncm=* parameters must be specified.

If the nc=* parameter is specified, then the ncm=* parameter must be specified.

If the zone=* parameter is specified, then the area=* and the id=* parameters must be specified.

If the area=* parameter is specified, then the id=* parameter must be specified.

If the msa=* parameter is specified, then the ssa=* and the sp=* parameters must be specified.

If the un=* parameter is specified, then the sna=* and the mna=* parameters must be specified.

If the ssa=* parameter is specified, then the sp=* parameter must be specified.

If the sna=* parameter is specified, then the mna=* parameter must be specified.

If the value of the nsfi=stop parameter is specified, then the nsr parameter cannot be specified.

If the nsr parameter is specified, then the actname parameter cannot be specified.

If the actname parameter is specified, then the nsfi=stop parameter must be specified.

The value of the actname parameter must already be defined in the Gateway Screening Stop Action table with the chg-gws-actset command. These values are shown in the ACT NAME field of the rtrv-gws-actset command output.

If the actname parameter is specified with the screening reference name parameter, the specified value for the actname parameter must be assigned to that screening reference name.

Any specified npc parameter must already exist in the allowed DPC entity for the screening reference.

Any specified ncm parameter must already exist in the allowed DPC entity for the screening reference.

Any specified nc parameter must already exist in the allowed DPC entity for the screening reference.

Any specified nsfi parameter must already exist in the allowed DPC entity for the screening reference.

Any specified nsr parameter must already exist in the allowed DPC entity for the screening reference.

Any specified pcst parameter must already exist in the allowed DPC entity for the screening reference.

Any specified area, sna or ssa parameter must already exist in the allowed DPC entity for the screening reference.

Any specified id, mna or sp parameter must already exist in the allowed DPC entity for the screening reference.

Any specified zone, un or msa parameter must already exist in the allowed DPC entity for the screening reference.

If the nsfi=fail parameter is specified, then the ni, nc, ncm, area, zone, nid, msa, ssa, sp, un, sna, mna, and npc parameters cannot have a value of c.

The Gateway Screening Stop Action table must be accessible.

The GWSOA parameter combination should be known and valid.

Notes

This command can be canceled using the F9 function key or the canc-cmd command. See canc-cmd for more information.

If no parameters are specified, a list of allowed DPC references is displayed indicating whether they are referenced or not.

If a single allowed DPC screening reference is specified, the specified entity set requested is shown.

If all=yes and no other parameter is specified, detailed information for all of the screening reference entities in the allowed DPC entity set are shown.

If the all parameter is specified and other parameters are also specified, the all parameter is ignored.

An asterisk as a parameter value in this command displays only entries that have an asterisk as the same parameter value in the entry.

A range of values is specified by separating the values that define the range by two ampersands (&&); for example, ni=025&&100 specifies all network indicators for ANSI point codes from 25 - 100 .

The spare point code subtype prefix (s-) is supported only for ITU international and ITU national point codes. The pcst parameter indicates whether the specified point code has no subtype prefix or has the spare point code prefix.

Legend

For a summary report:

REF—Indicates whether a screen is referenced by another screen. If NO, the screen is not used. For more detailed output, use the rtrv-scr-dpc:all=yes command, or specify the specific screening reference.
RULES—Number of screening rules in that screening table

For a detailed report:

SCREEN = ALLOWED DPC—Screen type
SR—Identifies the screen sets being used. It can be up to four characters in length.
NI-NC-NCM—Point code referenced within the screen. For international point codes, these columns are ZONE-AREA-ID. For 24-bit ITU national point codes, these columns are MSA-SSA-SP. For 16-bit ITU national point codes, these columns are UN-SNA-MNA. For national point codes, these columns become the single column NPC.
NSFI—Next screening category to be used
NSR/ACT—Name of the next screening reference (NSR - up to four characters) or action to be taken (ACT - up to six characters), if the message passes this screen.
