Example

dlt-scr-blkdpc:sr=iec:ni=240:nc=010:ncm=010

dlt-scr-blkdpc:sr=bdp1:un=125:sna=12:mna=17

Dependencies

At least one optional parameter must be specified.

A complete point code must be specified, using the ni-nc-ncm, zone-area-id, msa-ssa-sp, un-sna-mna, or npc combination unless a value of c is specified.

The blocked DPC or blocked DPC range specified by ni-nc-ncm, zone-area-id, msa-ssa-sp, un-sna-mna, or the npc parameter must already exist in the specified screening reference.

The point code to delete cannot have the value c-c-c if there is another point code in the blocked screening reference. The last screening reference to be deleted must have ni, zone, msa, un, or npc equal to c.

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

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

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

If the msa=c parameter is specified, then the ssa and sp parameters must have a value of c or must not be specified. If the msa=c parameter is specified, and the ssa and the sp parameters are not specified, then the ssa and sp parameters default to a value of c.

If the un=c parameter is specified, then the sna and mna parameters must have a value of c or must not be specified. If the un=c parameter is specified, and the sna and the mna parameters are not specified, then the sna and mna parameters default to a value of c.

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 of 0–255, the n 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.

If the ni=c parameter is specified, then the nc and the ncm parameters must have a value of c or must not be specified. If the ni=c parameter is specified, and the nc and the ncm parameters are not specified, then the nc and ncm parameters default to a value of c.

The last screening reference (sr) entry cannot be deleted if it is referenced by another screen.

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 zone=c parameter is specified, then the area and id parameters must have a value of c or must not be specified. If the zone=c parameter is specified, and the area and the id parameters are not specified, then the area and id parameters default to a value of c.

The GWSOA parameter combination should be known and valid.

Notes

If the screening reference is not referenced by any other screen, and if all entries are removed, the entire screening reference can be removed using ni-nc-ncm, zone-area-id, un-sna-mna, or msa-ssa-sp equal to c or npc=c. If more than one entry exists, ni-nc-ncm, zone-area-id, msa-ssa-sp, un-sna-mna, or npc cannot equal c.

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-blkdpc: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-blkdpc output with asterisks as the same parameter values specified in the dlt-scr-blkdpc command.

The asterisk (*) value cannot be specified with the character c. For example, a point code c-c-c is not allowed.

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 character c is used in the blocked DPC screens to allow the screening process to continue for messages with point codes that do not match any point codes in the blocked DPC screens. When screening for a blocked DPC and the point code being screened does not match any of the point codes in the blocked DPC screens, the message is not rejected and the screening process continues.

There must be an entry in each unique blocked DPC screening reference to allow the screening process to continue. This entry consists of a screening reference, point code, nsfi, and nsr. The point code is in the form of subfields ni-nc-ncm, zone-area-id, un-sna-mna or msa-ssa-sp equal to c-c-c or npc=c. When the character c is specified, the nsfi and nsr parameters must be specified.

When the point code does not match any entries in the blocked DPC screens, the screening process is directed to the screening reference with the point code c. The nsfi and nsr in this entry are examined to determine the next step in the screening process.

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.
