Adding an Allowed Affected Point Code Screen
This procedure is used to add an allowed affected point
code (AFTPC) screen to the database using the
ent-scr-aftpc command. The parameters
used by the
ent-scr-aftpc command are shown in the
Gateway Screening Attributes
section. The general rules that apply to configuring gateway screening entities
are shown in the
Gateway Screening Configuration
section.
The examples in this procedure are used to add the allowed AFTPC screen data shown in Table 3-1 and based on the example configurations shown in Figure 2-3 and Figure 2-6.
Table 3-1 Example Gateway Screening Allowed AFTPC Configuration Table
| Screening Reference | NI | NC | NCM | SSN | NSFI | ACTNAME |
|---|---|---|---|---|---|---|
| gw20 | 008 | 008 | 008 | 250 | stop | COPY |
| ls04 | 010 | 010 | 010 | 015 | stop | COPY |
Note:
If you using multiple-part ITU national point codes with gateway screening, see the 14-Bit ITU National Point Code Formats section.Specifying a Range of Values
A range of values can be specified for the point code
parameters
ni,
nc, or
ncm.
If a range of values is specified for any of these parameters, and the value of the other parameters match existing values for the screening reference name, the range of values for the point code parameter cannot include any values for that parameter that are currently provisioned for the screening reference name.
For example, screening reference name
scr1 contains these entries:
SR NI NC NCM SSN NSFI NSR/ACT
SCR1 240 001 010 012 STOP ------
SCR1 241 010 020 015 STOP ------Another entry for screening reference
scr1 with the
ni value of 240 and the
nc value of 001 cannot be specified if
the range of values for the
ncm parameter includes the value 010.
The ANSI point code parameter values can be specified as
a single value, a range of values, or with an asterisk (*). The asterisk
specifies all possible values for the
ni,
nc, and
ncm parameters.
Table 3-2
shows the valid combinations of these parameter values.
Table 3-2 Valid Value Combinations for ANSI Point Code Parameters
| NI | NC | NCM |
|---|---|---|
| Single Value | Single Value | Single Value |
| Single Value | Single Value | Range of Values |
| Single Value | Single Value | Asterisk |
| Single Value | Range of Values | Asterisk |
| Single Value | Asterisk | Asterisk |
| Range of Values | Asterisk | Asterisk |
| Asterisk | Asterisk | Asterisk |
A range of values can also be specified for an ITU-I or 24-bit ITU-N point code parameter using a combination of asterisks (*) and single values for the point code parameters. Table 3-3 shows the valid combinations of the ITU-I parameter values. Table 3-4 shows the valid combinations of the 24-bit ITU-N parameter values.
