Removing an Allowed Affected Point Code Screen

This procedure is used to remove an allowed affected point code (AFTPC) screen from the database using the dlt-scr-aftpc command. The parameters used by the dlt-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 example in this procedure removes the allowed AFTPC screen wrd0 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.

Display the allowed AFTPC screens in the database using the rtrv-scr-aftpc command.
The following is an example of the possible output.
```
rlghncxa03w 06-10-25 15:25:30 GMT EAGLE5 36.0.0
SCREEN = ALLOWED AFTPC
SR    REF  RULES
GW20  YES     1
IEC   YES     2
LS04  YES     1
WRD0  YES     1
WRD2  YES     1
WRD4  YES     9
```
From the rtrv-scr-aftpc output, display the allowed AFTPC screen you wish to remove using the rtrv-scr-aftpc command with the screening reference name. For this example, enter the rtrv-scr-aftpc:sr=wrd0 command. The following is an example of the possible output.
```
rlghncxa03w 06-10-25 15:25:30 GMT  EAGLE5 36.0.0
SCREEN = ALLOWED AFTPC
SR      ZONE   AREA     ID       SSN      NSFI    NSR/ACT
WRD0    1      004      6        023      STOP    ------
```
An allowed AFTPC screen can only be referenced by an allowed CDPA screen.
Verify any references to the allowed AFTPC screen being removed from the database using the rtrv-scr-cdpa:nsfi=aftpc command. The following is an example of the possible output.
```
rlghncxa03w 06-10-25 15:26:30 GMT  EAGLE5 36.0.0
SCREEN = ALLOWED CDPA
SR      ZONE   AREA    ID        SSN      SCMGFID  NSFI    NSR/ACT
IEC     1      134     *         001      002      AFTPC   IEC

SR      ZONE   AREA    ID        SSN      SCMGFID  NSFI    NSR/ACT
WRD1    1      004     6         001      005      AFTPC   WRD0

SR      NPC                      SSN      SCMGFID  NSFI    NSR/ACT
WRD4    12345                    001      100      AFTPC   IEC
```
If the screen being removed is referenced by any CDPA screens, perform the Changing an Allowed Called Party Address Screen procedure to change the NSFI of those CDPA screens to reference other AFTPC screens or change the NSFI of these screens to STOP.
Remove the allowed AFTPC screen from the database using the dlt-scr-aftpc command with the screening reference name shown in the rtrv-scr-aftpc output in step 1 and with the point code parameter values (ni, nc, ncm, or zone, area, id, or npc, or msa, ssa, sp) and the ssn parameter value of the screen being removed from the database.
The values for these parameters must be entered exactly as shown in the rtrv-scr-aftpc output.

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-aftpc 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-aftpc command. If the pcst parameter is specified, the value must be none.

For this example, enter this command.

dlt-scr-aftpc:sr=wrd0:zone=1:area=004:id=6:ssn=023

A message similar to the following should appear.
```
rlghncxa03w 06-10-25 15:29:30 GMT  EAGLE5 36.0.0
DLT-SCR-AFTPC: SCREEN SET AFFECTED - WRD0  0% FULL
DLT-SCR-AFTPC: MASP A - COMPLTD
```
Verify the changes using the rtrv-scr-aftpc command with screening reference name used in step 3.
For this example, enter this command.

rtrv-scr-aftpc:sr=wrd0

The following message should appear.
```
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-aftpc command in step 5 was successful. If the specified screening reference name contained more than one entry when the dlt-scr-aftpc command was executed in step 4, the rtrv-scr-aftpc: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.
