Adding an Allowed Calling Party Address Screen
This procedure is used to add an allowed calling party
address (CGPA) screen to the database using the
ent-scr-cgpa
command. The parameters
used by the
ent-scr-cgpa
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 CGPA screen data shown in Table 6-2 and based on the example configurations shown in Figure 2-3 through Figure 2-5.
Table 6-2 Example Gateway Screening Allowed CGPA Configuration Table
Screening Reference | ZONE | AREA | ID | SN | RI | SCCPMT | NSFI | NSR |
---|---|---|---|---|---|---|---|---|
gw11 | 7 | 100 | 4 | 254 | * | 010 | cdpa | gw15 |
Screening Reference | NI | NC | NCM | SSN | RI | SCCPMT | NSFI | NSR |
---|---|---|---|---|---|---|---|---|
gw13 | 007 | 007 | 007 | 250 | gt | 017 | tt | gw16 |
gw14 | 006 | 006 | 006 | 253 | dpc | 009 | cdpa | gw17 |
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 CGPA screen can reference one of the following screens.
- Allowed TT
- Allowed CDPA
Verifying the Gateway Screening Configuration
Enter the following commands to verify that these screens are in the database.
rtrv-scr-tt:all=yes
rtrv-scr-cdpa:all=yes
Gateway Screening Configuration Procedures
If the desired screen is not in the database, perform one of the following procedures to add the desired screen to the database or change an existing screen in the database.
- Adding an Allowed Translation Type Screen
- Adding an Allowed Called Party Address Screen
- Changing an Allowed Translation Type Screen
- Changing an Allowed Called Party Address Screen
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 RI SCCPMT NSFI NSR/ACT
SCR1 240 001 010 012 DPC 009 STOP ------
SCR1 241 010 020 * GT 017 TT SCR1
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 6-3
shows the valid combinations of these parameter values.

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 6-4 shows the valid combinations of the ITU-I parameter values. Table 6-5 shows the valid combinations of the 24-bit ITU-N parameter values.
