Adding an Allowed Called Party Address Screen
This procedure is used to add an allowed called party
address (CDPA) screen to the database using the
ent-scr-cdpa command. The parameters
used by the
ent-scr-cdpa 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 CDPA screen data shown in Table 4-1 and based on the example configurations shown in Figure 2-3 through Figure 2-6.
Table 4-1 Example Gateway Screening Allowed CDPA Configuration Table
| Screening Reference | ZONE | AREA | ID | SSN | SCMGFID | NSFI | NSR |
|---|---|---|---|---|---|---|---|
| gw15 | 5 | 117 | 2 | 254 | ---- | stop | ---- |
| Screening Reference | NI | NC | NCM | SSN | SCMGFID | NSFI | NSR |
|---|---|---|---|---|---|---|---|
| gw17 | 003 | 003 | 003 | 001 | 050 | aftpc | gw20 |
| gw18 | 006 | 006 | 006 | 253 | ---- | stop | ---- |
| ls03 | 007 | 007 | 007 | 001 | 100 | aftpc | ls04 |
Note:
If you using multiple-part ITU national point codes with gateway screening, see the 14-Bit ITU National Point Code Formats section.The allowed CDPA screen can only reference an allowed
AFTPC screen and the allowed AFTPC screen being referenced must be in the
database. This can be verified using the
rtrv-scr-aftpc:all=yes command. If the
desired allowed AFTPC screen is not in the database, perform one of these
procedures to add the required screen to the database or change an existing
screen in the database.
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 SCMGFID NSFI NSR/ACT
SCR1 240 001 010 012 ------ STOP ------
SCR1 241 010 020 001 002 AFTPC SCR1Another 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 4-2
shows the valid combinations of these parameter values.
Table 4-2 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 4-3 shows the valid combinations of the ITU-I parameter values. Table 4-4 shows the valid combinations of the 24-bit ITU-N parameter values.
