Feature Overview

Simple INAP is required to support functionality within MML that allows for the simple provisioning of some of the message sending parameters within the trigger.dat table that mainly affect Signaling Connection Control Part (SCCP).

The Service Key value is not standard in EMEA and depends on the SCP and the defined services.

For EMEA, the SCCP default values for routing for should be set to be SSN and not set to Global Title.

Benefits

Customizing the trigger.dat Entries

The generic customizable trigger.dat entry is added with a simple EMEA format for sending and receiving. For example, for a generic translation type service that is similar to TT17.

Configuring Fields within the Message Sending Table

This feature allows the user to configure the parameters F6 Service Key or Trigger Criteria value, F9 gtSSN, and F16 gtFormat within the Message Sending (MS) table data in the additional IN Service table in the trigger.dat file.

Removed Unused Fields from the Message Sending.dat File

Table 1 lists the previous Message Sending.dat fields, the fields that have migrated to the STP.dat file, and the fields that exist in the current Message Sending.dat file.

Restrictions

Support for Field 15 SSN is now moved to the STP.dat file, which is currently configurable. If Field 11 SSNPRES is enabled, data from Field 15 is migrated to the STP.dat file.

Caution Improperly editing the trigger.dat file can cause service interruption and prevent the Cisco MGC from correctly performing SCP database queries.

Note SSN has been renamed LOCALSSN to clarify the intent of the parameter. There is continued support of SSN for the MML command line. If both SSN and LOCALSSN are specified, LOCALSSN is used. When using the prov-exp command, LOCALSSN is used.

For information on the rest of the components in the Cisco MGC software, refer to the Cisco Media Gateway Controller Software Release 9 Provisioning Guide.

Saving

The data is available for call processing after the session that the messaging sending information is configured in has been made active using either prov-cpy or prov-dply.

Provisioning Example

The intelligent network service can be changed at any time, as it is dynamically re-configurable.

The following MML commands allow you to add, retrieve, edit, and delete information related to the to intelligent network service functionality.

Intelligent Network Service Creating Example

Example of creating intelligent network service entries:

prov-add:inservice:name="serviceone",skortcv=37,gtorssn="routebygt",gtformat="gttt",msname ="generic_lnp"
prov-add:inservice:name="servicetwo",skortcv=0,gtorssn="routebyssn",gtformat="nogt"

Intelligent Network Service Editing Example

To add a entry for intelligent network service one:

prov-ed:inservice:name="serviceone",skortcv=255

Intelligent Network Service Deleting Example

To delete the intelligent network service:

prov-dlt:inservice:name="serviceone"

Intelligent Network Service Retrieving Example

To retrieve all of the intelligent network services:

prov-rtrv:inservice:"all"

To retrieve the intelligent network service one:

prov-rtrv:inservice:name="serviceone"

Record Type Message Sending (MS) Table

The Message Sending table is a collection of data necessary to send a TCAP message. The previous fields are listed in the first column, the migrated fields are listed in the second column, and the current table fields are listed in the third column of Table 1.

The MDL parameter for ssnPres is always passed to the TCAP with a value of false.

The Message Sending table exists in the trigger.dat file. The Message Sending table has been modified to support the current 11 parameters instead of the 21 parameters it previously supported.

Packaging and Installation Scripts

Currently the trigger.template is installed onto the system during installation. If there is a trigger.dat file currently in the /<BASEDIR>/etc directory then it is left. However, if a trigger.dat file is not present, the trigger.template file is copied to trigger.dat. In the clearcase repository the file is stored as /vobs/NSSU_Main/callproc/Tables.trigger.

To support this feature, information in the trigger.dat file, which is now configurable, is moved to the inService.dat file. The inService.dat file is handled the same as other *.dat files in the system, which is installed into the file /<BASEDIR>/etc/CONFIG_LIB/new/inService.dat.

Migration

When migrating to a software release that supports INAP provisioning, the trigger.dat file is migrated and the inService.dat file is created. Also, the file stp.dat has three more columns added to it.

During installation, the trigger file treatment remains unchanged and is copied from the /<BASEDIR>/etc directory to the /<BASEDIR>/etc/CONFIG_LIB/INSTALL-<version>/previous directory. For example, if the BASEDIR was opt/CiscoMGC and the version was 9.2.2, the directory would be /opt/CiscoMGC/etc/CONFIG_LIB/new/INSTALL-<version>/previous 9.2.2, and the migrated contents of this directory are placed in /<BASEDIR>/etc/CONFIG_LIB/new/INSTALL-<version>/migrated.

When this feature is installed onto the MGC, the trigger.dat message-sending table is migrated to the new format at this time. If the data is migrated successfully, then the directory /<BASEDIR>/etc/CONFIG_LIB/CFG_Migrated becomes the active link with the files from the migrated directory.

When migrating to a software release that supports INAP provisioning, the trigger.dat file is installed in <BASEDIR>/etc as trigger.dat.new. If you do not want to use the migrated trigger.dat and inService.dat files, you can do the following:

•Copy trigger.dat.new to trigger.dat in <BASEDIR>/etc

•Delete all of the entries in the inService.dat file using prov-dlt

•Reprovision the entries in the inService.dat file using prov-add

You can choose to do this if you would like to use the more meaningful names in the trigger.dat file and in the inService.dat file.

Configuring the Translation Type Attribute

Perform the following steps to configure the Translation Type (translationType) attribute:

Step 1 Back up the trigger.dat file.

Step 2 Determine the Trigger Number you are to edit. Get this information from your network administrator.

Step 3 Navigate to directory /opt/CiscoMGC/etc.

Step 4 Open the trigger definition file in an ASCII text editor and search for the string $TriggerTable.

Step 5 Starting after the $TriggerTable line, count the number of rows that equal to the TriggerType beginning from the number 1.

Note Do not count any row that is blank or begins with a # (pound sign).

Step 6 When you find your row, write down the second number in that row, which is the index to the $MessageSending table.

Caution You must verify that column 1 is equal to 2 or 3 before changing Translation Type. If column 1 is not equal to 2 or 3, it is not an ANSI trigger and Translation Type is not used.

Step 7 Edit the file as follows:

a. In the $MessageSending table, select translationType, in column 5 (see Table 3).

b. In the table for your translation type, change the value (from 0 through 255) for your translationType, which you can get from your network administrator.

Step 8 Save your changes and close the editor.

Step 9 For your changes to take effect you must reboot the Cisco MGC by entering the following command:

# /etc/init.d/CiscoMGC start

Initializing the Call Screening Database

Caution Cisco does not support the direct use of TimesTen commands (files found in /opt/TimesTen/32/bin). Incorrect use of these commands can cause database corruption.

During installation, the installation script (install.sh) installs and initializes the Main Memory Database (MMDB) that the Cisco MGC can use for the following:

•Store call-screening information for calling- and called-number analysis

•Ported Numbers

•Number Termination

•Multiple Dial Plan

•Advice of Charge II

You can perform whitelist and black list screening to include or exclude calls from certain numbers. You can provision white lists that specify allowed A-numbers (calling numbers) or B-numbers (called numbers). Black lists block specified A-numbers (calling numbers) or B-numbers (called numbers).

Note When provisioning dial plans, the *.SysConnectDataAccess property (in XECfgParm.dat) must be set to true to allow database access for A-number screening, LNP, and other dial plan functions. Refer to the Cisco Media Gateway Controller Software Release 9 Installation and Configuration Guide for more information on software configuration settings.

The call screening database is stored in the /opt/TimesTen/datastore directory. The database name is howdydb. The maximum database size, 256 MB, is specified in the .odbc.ini file.

Caution Do not change the database name.
