4.256 dlt-scr-sio

Use this command to remove a specific screening reference from the allowed service indicator octet (SIO) category.

Parameters

nic (mandatory)
Network indicator code. This parameter specifies whether the message originated from an international (0) or national (2) network.
Range:
0 - 3, *

*—the full range of values from 0–255

pri (mandatory)
New message priority. The new message priority in the SIO.
Range: 0 - 3, *
*—the full range of values from 0–255
Default:
Current value
si (mandatory)
Service indicator. The service indicator identifies the type of message. The values are defined in Telcordia TR-NWT-000246.
Range:
00
01-15
sr (mandatory)
Screening reference. The point code’s unique screening reference name.
Range:
ayyy

1 alphabetic character followed by up to 3 alphanumeric characters

h0 (optional)
This parameter is mandatory if the si parameter has a value of 00, 01, 02, or 03. Otherwise, the h0 parameter is undefined.
Range:
0 - 15
Default:
Current value or undefined
h1 (optional)
This parameter is mandatory if the si parameter has a value of 00, 01, 02, or 03. Otherwise, the h1 parameter is undefined.
Range:
0 - 15
Default:
Current value or undefined

Example

dlt-scr-sio:sr=iec:nic=1:si=1:h0=4:h1=2:pri=*

dlt-scr-sio:sr=iec:nic=1:si=3:pri=2

Dependencies

The h0 and h1 parameters cannot be specified if the si parameter is specified and is not equal to 00, 01, or 02.

The parameter to be removed must be in the screening reference.

Valid combinations for the h0/h1 parameters: 

  • h0 is a single value— h1 can be a single value, range, or an asterisk
  • h0 is a range— h1 can be an asterisk
  • h0 is an asterisk— h1 can be an asterisk

The sr, nic, si, pri, and h0/h1 parameters cannot be removed if they are the last entry in the screening reference and the screening reference is part of a screen set.

If the si parameter has value of 00, 01, or 02, the h0 and h1 parameters must be specified. Otherwise, the h0 parameter cannot be specified.

If the value of the si parameter value is greater than 2, then the h0 and h1 parameters cannot be specified.

If asterisks or ranges are specified for the heading codes, nothing that matches the +combination of nic, si, and the specified heading codes can already exist in the allowed SIO entity set for the screening reference.

The specified screening reference (sr) must already exist in the database.

The GWSOA parameter combination should be known and valid.

For SEAS commands, the pri parameter specified must be in the range 0-3, *.

For SEAS commands, the h0 parameter specified must be in the range 0-15, *.

For SEAS commands, the h1 parameter specified must be in the range 0-15, *.

Notes

The network identifier specifies whether the message originated from an international (0) or a national (2) network.

The asterisk is a parameter value indicating that the gateway screening process is screening all values for that parameter in the MSU. The asterisk parameter value does not mean that multiple entries whose values may be in the range implied by the asterisk will be removed. The only entry that will be removed by this command when the asterisk is specified as a parameter value is the entry that contains an asterisk as that parameter value.

For example, if the dlt-scr-sio:sr=ied:ni=240:nc=010:nccm=":ssn=* command is entered, the only entry that will be removed from the database is the entry in screening reference iec that contains the values ni=240, nc=010, ncm=*, and ssn=*. For an entry to be specified in this command with asterisks as parameter values, that entry must be shown in the rtrv-scr-sio output with asterisks as the same parameter values specified in the dlt-scr-sio command.

A range of values is specified by separating the values that define the range by two ampersands (&&); for example, ni=025&&100 specifies all network indicators for ANSI point codes from 25 - 100.
