Example

dlt-scr-aftpc:sr=iec:ni=240:nc=010:ncm=010:ssn=012

dlt-scr-aftpc:sr=aft1:zone=1:area=2:id=3:ssn=1:pcst=s

dlt-scr-aftpc:sr=aft2:un=1:sna=2:mna=3:ssn=1

Dependencies

A complete point code must be specified, and must be one, and only one of the five point code parameter combinations: ni-nc-ncm, zone-area-id, msa-ssa-sp, un-sna-mna or npc.

The affected point code or point code range (given by ni-nc-ncm/ssn, zone-area-id, msa-ssa-sp, un-sna-mna or npc) to be removed from the table must already exist in the screening reference.

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

If asterisk values are specified, the range cannot overlap or contain any of the point code ranges that already exist in the allowed affected point code screening category.

If zone=* is specified, area=* and id=* must be specified.

If area=* is specified, id=* must be specified.

If ssa=* is specified, sp=* must be specified.

If msa=* is specified, ssa=* and sp=* must be specified.

If sna=* is specified, mna=* must be specified.

If un=* is specified, sna=* and mna=* must be specified.

If the nc parameter is specified as a range, the ncm parameter must be specified as an asterisk or as the full range.

If the nc parameter is specified as a single value or a range, a single value must be specified for the ni parameter.

If the nc parameter is specified as an asterisk, the ncm parameter must be specified as an asterisk or as the full range.

If the ncm parameter is specified as a single value, or a range other than the full range 0-255, the ni and the nc parameters must be specified with a single value.

If the ni parameter is specified as an asterisk or as a range, the nc and ncm parameters must be specified as an asterisk or as the full range.

The character c is not a valid value for the ni, nc, ncm, zone, area, id, msa, ssa, sp, un, sna, mna, and npc parameters.

The specified screening reference (sr) must already exist in the database.

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-N24 or ITU-N16 point codes.

No AFTPC screening reference (sr) can be deleted that is referenced by an entity in another screening set.

The sr, ni, nc, ncm, and ssn parameters, or the zone, area, id, and npc parameters cannot be deleted if they are the last entry in the screening reference and the screening reference is part of a screen set.

If only one entry exists, the sr cannot be referenced by another screening table. If the sr is not referenced by another screening table, the entire screening table is deleted.

The GWSOA parameter combination should be known and valid.

Notes

The asterisk is a parameter value indicating that the gateway screening process is screening all values for that parameter in the MSU. The asterisk parameter value does not mean that multiple entries whose values may be in the range implied by the asterisk will be removed. The only entry that will be removed by this command when the asterisk is specified as a parameter value is the entry that contains an asterisk as that parameter value.

For example, if the dlt-scr-aftpc:sr=ied:ni=240:nc=010:nccm=":ssn=* command is entered, the only entry that will be removed from the database is the entry in screening reference iec that contains the values ni=240, nc=010, ncm=*, and ssn=*. For an entry to be specified in this command with asterisks as parameter values, that entry must be shown in the rtrv-scr-aftpc output with asterisks as the same parameter values specified in the dlt-scr-aftpc command.

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.
