4.112 chg-prefix

Use this command to enter the name of a feature, the value of a prefix used by the feature, and a prefix number that is used to refer to the prefix from another table.

Parameters

feature (mandatory)
Feature Name. The name of an enabled controlled feature supported by this command. The parameter value must match the feature name as it is displayed in the rtrv-ctrl-feat command output.
Range:
azzzzzzzzzzzzzzzzzzzzzzzz

1 alphabetic character and up to 24 optional alphanumeric characters and spaces, enclosed in double quotation marks

The parameter value is not case-sensitive; upper case or lower case or both can be entered.

Part or all of the feature name can be entered. If part of the feature name is specified, the entry must start with the first letter of the name, and must contain enough of the name to uniquely identify the feature. For example, there are two feature names that begin with “GSM MAP.” Enough additional characters to identify which GSM MAP feature is being entered (at least “GSM MAP SR” to identify the “GSM MAP SRI Redirect” feature). This command supports the following controlled features:

  • GSM MAP SRI Redirect
  • ISUP NP for EPAP
prefix (mandatory)
Prefix Value. Prefix table entries for the GSM MAP SRI Redirect and ISUP NP with EPAP features.
Range:
1-15 hexadecimal digits. Valid digits are 0-9, a-f, A-F
Default:
Current value
prefixnum (mandatory)
Prefix Number. The prefix value to use for the specified feature name.
Range:
1 - 7

1 - 128 for GSM MAP SRI Redirect feature prefix values

1-5 for ISUP NP with EPAP feature prefix values

6 for the ISUP NP with EPAP feature Insertion Country Code

7 for the ISUP NP with EPAP feature Deletion Condition value

Default:
No change to the current value

Example

Define a prefix with prefix number 1 for the ISUP NP with EPAP feature.

chg-prefix:feature="isup np with epap":prefix=1004:prefixnum=1

Define a prefix with prefix number 2 and specify part of the GSM MAP SRI Redirect feature name.

chg–prefix:feature="GSM MAP SRI":prefix=104:prefixnum=2

Define a prefix with prefix number 6 and specify part of the GSM MAP SRI Redirect feature name.

chg-prefix:feature=”GSM MAP SRI Redirect”:prefix=1006:prefixnum=6

Dependencies

The specified feature name value (feature parameter) must be enclosed in double quotation marks

(" ").

The GSM MAP SRI Redirect feature must be enabled before a GSM MAP SRI Redirect prefix can be defined.

The ISUP NP with EPAP feature must be enabled before an ISUP NP with EPAP prefix can be defined.

The specified prefix value must contain a number of digits that is equal to or less than the maximum number of digits required by the specified feature.

The specified prefix number (prefixnum) must be valid for the specified feature.

The specified feature name must be the name of an enabled controlled feature as it is displayed in the rtrv-ctrl-feat command output. The specified feature must be the GSM MAP SRI Redirect or ISUP NP for EPAP feature.

The FEATPFX table is corrupt or cannot be found by the system.

The FEATPFX table cannot be full when a new entry is added.

Notes

The Prefix table contains different groups of entries based on the features that are turned on. For the GSM MAP SRI Redirect for Serving HLR feature, the entries are referenced by the VendID table, based on a Vendor Number matching a Prefix Number. For the ISUP NP with EPAP feature, the entries are referenced by the SubnetID table, based on a Subnet Number matching a Prefix Number. The Prefix table for the ISUP NP with EPAP feature also reserves Prefix Number 6 for the Insertion Country Code value, and reserves Prefix Number 7 for the Deletion Condition value. Figure 4-7  illustrates the references to the Prefix table.

* Reserved for the ISUP NP with EPAP feature Insertion Country Code value

** Reserved for the ISUP NP with EPAP feature Deletion Condition value

For the ISUP NP with EPAP feature:

  • When the Insertion Country Code (prefix number 6) is defined, the following information message appears:

    ISUP NP with EPAP, Insertion Country Code value is now defined

  • When the Deletion Condition (prefix number 7) is defined, the following information message appears:

    ISUP NP with EPAP, Deletion Condition value is now defined

The maximum number of prefixes that can be defined is:

  • 128 for the GSM MAP SRI Redirect feature
  • 5 values, 1 Insertion Country Code, and 1 Deletion Condition for the ISUP NP with EPAP feature
