Removing an Allowed Called Party Address Screen

This procedure is used to remove an allowed called party address (CDPA) screen from the database using the dlt-scr-cdpa command. The parameters used by the dlt-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 example in this procedure removes the allowed CDPA screen gw17 from the database.

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 be referenced by one of the following screens.

Allowed SIO
Allowed CGPA
Allowed TT

Verifying the Gateway Screening Configuration

Enter the following commands to verify that none of these screens reference the allowed CDPA screen being removed from the database.

rtrv-scr-sio:nsfi=cdpa
rtrv-scr-cgpa:nsfi=cdpa
rtrv-scr-tt:nsfi=cdpa

Gateway Screening Configuration Procedures

To change the NSFI of any of these screens, preform one of these procedures.

Display the allowed CDPA screens in the database using the rtrv-scr-cdpa command.
The following is an example of the possible output.
```
rlghncxa03w 06-10-25 15:25:30 GMT  EAGLE5 36.0.0
SCREEN = ALLOWED CDPA
SR    REF  RULES
GW15  YES     1
GW17  YES     1
GW18  YES     1
IEC   YES     2
LS03  YES     1
WRD2  YES     1
WRD4  YES     9
```
From the rtrv-scr-cdpa output, display the allowed CDPA screen you wish to remove using the rtrv-scr-cdpa command with the screening reference name. For this example, enter the rtrv-scr-cdpa:sr=gw17 command. The following is an example of the possible output.

The following is an example of the possible output.
```
rlghncxa03w 06-10-25 15:25:30 GMT  EAGLE5 36.0.0
SCREEN = ALLOWED CDPA
SR    NI       NC      NCM       SSN      SCMGFID  NSFI    NSR/ACT
GW17  003      003     003       001      050      AFTPC   GW20
```
Enter the commands in the Verifying the Gateway Screening Configuration section to verify that the screen being removed is not referenced by other screens in the database.

If the screen being removed is referenced by other screens, perform the procedures shown in the Gateway Screening Configuration Procedures section to change the NSFI of those screens to reference other screens or change the NSFI of these screens to STOP.
Remove the allowed CDPA screen from the database using the dlt-scr-cdpa command.
The current values for the ni, nc, ncm, zone, area, id, npc, msa, ssa, sp, and ssn parameters must be entered exactly as shown in the rtrv-scr-cdpa output in 1.
To remove an entry containing either an ITU-I or a 14-bit ITU-N spare point code, the pcst=s parameter must be specified with the dlt-scr-cdpa command.

To remove an entry containing either an ITU-I or a 14-bit ITU-N non-spare point code, the pcst parameter does not have to be specified with the dlt-scr-cdpa command. If the pcst parameter is specified, the value must be none.

For this command, enter this command:

dlt-scr-cdpa:sr=gw17:ni=003:nc=003:ncm=003:ssn=001

A message similar to the following should appear.
```
rlghncxa03w 06-10-25 15:26:30 GMT  EAGLE5 36.0.0
DLT-SCR-CDPA: SCREEN SET AFFECTED - GW17  0% FULL
DLT-SCR-CDPA: MASP A - COMPLTD
```
Verify the changes using the rtrv-scr-cdpa command with the screening reference name used in 3 .
For this example, enter this command.

rtrv-scr-cdpa:sr=gw17

The following is an example of the possible output.
```
E2573 Cmd Rej: SR or NSR does not reference an existing SR
```
This message shows that the specified screening reference name is not in the database and the action of the dlt-scr-cdpa command in 3 was successful. If the specified screening reference name contained more than one entry when the dlt-scr-cdpa command was executed in 3 , the rtrv-scr-cdpa:sr= command output would show the remaining entries in the screening reference instead of error message E2573.

Backup the new changes using the chg-db:action=backup:dest=fixed command.

The following messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.

BACKUP (FIXED) : MASP A - Backup starts on active MASP.
BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
