Notes

When a blocked DPC screening reference is created, the first entry for a point code must be c-c-c or npc=c parameter. Subsequent entries must be specific point codes.

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 the blocked DPC screens to allow the screening process to continue. This entry consists of a screening reference, point code, nsfi, and nsr. The point code is npc=c or subfields equal to c-c-c. When the character c is specified, the nsfi and nsr parameters must be specified.

If the character c is specified for the parameters ni-nc-ncm, zone-area-id, un-sna-mna, or msa-ssa-sp, the character c is the only value that can be specified for all three parameters. No other values can be used. For example, a point code c-c-255 is not allowed. The point code must be c-c-c. The asterisk (*) value cannot be used with the character c (for example, a point code c-c-* is not allowed).

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-c-c or npc=c. The nsfi and nsr in this entry are examined to determine the next step in the screening process.

If the current ni-nc-ncm, zone-area-id, un-sna-mna, or msa-ssa-sp is equal to c-c-c or npc=c, only the nsfi and nsr can be changed. Otherwise, only the blocked DPC can be changed.

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.

An asterisk cannot be specified for a parameter value in this command unless an asterisk was specified for the parameter value in the ent-scr-blkdpc command.

If the screen set reaches 100% capacity (indicated by the 100% Full message), the system allows subsequent entries. An error occurs, however, when downloading the screen set to an LIM. Ensure that screen sets do not exceed 100% capacity. Remove screen set entries until the capacity is below 100%.

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

There is no feature dependency on ANSI point code parameters i.e., ni, nc, ncm, nni, nnc, or nncm. The command can be entered successfully whether the J7 feature is enabled or not enabled.

If there are more than 200 affected screensets and the force parameter is set to yes, then the following warning message is displayed: "WARNING: Command may take up to 30 minutes" and the command proceeds successfully.

If there are more than 200 affected screensets and the force parameter is set to no, then the following notice is displayed: "Notice: Force parameter is required for affected screensets greater than 200" and the command is aborted.
