IMG 1010 - Generic Number Translation

Overview:

The IMG supports translating Incoming and Outgoing translations for the purpose of routing calls. Currently the IMG supports matching either the ‘Dialed’ or ‘Originating’ Number and translating it into one of the following parameters: Dialed #, Originating #, Billing #, Info Digits, or Carrier #. Feature F-1624 ‘Generic Number Translation’ adds the SS7 call message ‘Generic Number Parameter’ into multiple aspects of the Incoming/Outgoing Translation Table Object. Below describes which functionality was updated with the ‘Generic Number Translation’ Parameter.

• The Generic Number Parameter was added to the ‘String to Match’ field in both the Incoming and Outgoing Translation Table Entry Objects. By adding this parameter, the IMG can now route a call based on the value of the Generic Number Parameter which is embedded in the incoming ISUP messaging.

• The Generic Number Parameter can now also be translated. A Generic # Translation Field was added to the Incoming\Outgoing Translation Table Entry Object. By adding this field, the IMG can now match on an incoming Originating Number, Dialed Number, or Generic Number. The matched string can now be translated and sent to the Generic Number Parameter portion of ISUP messaging. The ISUP messaging is then interworked to the outgoing protocol.

• The Generic Number Parameter was added to the Re-Run Option within the Incoming/Outgoing Translation Table entry object. By adding the Generic Number Parameter the IMG can first match and translate a Dialed or Originating Number. Once this is accomplished and the Re-Run Option is set to ‘Generic Number’, the IMG will then search the translation table entries for another entry with the ‘String to Match’ field set to ‘Generic Number’. Once it finds the correct entry, the Generic Number is then translated again to a Dialed Number, Originating Number, Generic Number, Billing Number, Info Digits, or Carrier Number.

• A new object was added below the Incoming and Outgoing Translation Entry. The object is named ‘New Advanced Generic Number Translation’. The Advanced Generic Number Translation pane allows the IMG to be able to translate individual portions of the Generic Number Parameter. Information such as Nature of Address and Numbering Plan embedded in the Generic Number Parameter can now be translated. 

Below are steps needed to configure the different aspects of the Generic Number Translation feature. The procedure below assumes that initial configuration has already been accomplished and will focus on configuring F-1624. The procedure below configures F-1624 to be used in an SS7 to SIP configuration.

Procedure:

Initial Configuration:

The procedure below explains how to configure the IMG for feature F-1666. Verify the following entities are configured before proceeding:

• IMG 1010 - Logical IMG

• IMG 1010 - Physical IMG

• IMG 1010 - Configuring T1 or E1 Bearer Profile - 10.5.x

• IMG 1010 - IP Bearer Profile

• IMG 1010 - IP Network (Interface)

• IMG 1010 - Configuring T1 or E1 Bearer Spans - 10.5.x

• IMG 1010 - VoIP Resource

• IMG 1010 - ISDN Signaling Pane

• IMG 1010 - ISDN D Channel

Configure these initial objects before proceeding to the procedure below.

Configure SS7 Channel Group:

• Right Click on Dialogic IMG EMS and select New Routing Configuration. This object is a placeholder for multiple other routing objects and no configuration is completed under this object. See IMG 1010 - Routing Configuration Object for more information.

• Right Click on Routing Configuration and select New Channel Groups. No configuration is needed within the IMG 1010 - Channel Groups object. This object is configured so that multiple Channel Group objects can be configured below it.

• Right Click on the Channel Groups object and select New Channel Group. A Channel Group object will appear. Enter a Name and select SS7 from the ‘Signaling Type’ drop down menu within this object. See IMG 1010 - Channel Group for more information on configuring the SS7 Channel Group.

• Right Click on the SS7 Channel Group created and select New ISUP Group. See ISUP Group for more information on this object. 

Configure Generic Number Parameter in Translation Table Entries:

• Right Click on Routing Configuration and select New Incoming Translation Tables. A Incoming Translation Tables object will appear. This object is a placeholder for multiple Incoming Translation Tables. No configuration is completed in this object.

• Right Click on Incoming Translation Tables and select New Translation Table. Enter a name for this translation table. In this example it is labeled Inc_TT1.

• Right Click on the translation table object just created and select New Translation Entry. In the object that appears select Generic Number from drop down menu in the ‘String to Match’ field and enter a string to match. To translate the Generic Number enter a value in the ‘Generic Number Translation Field. See screen capture below See Incoming Translation Entry topic for more information on configuring the Incoming Translation Table Entry.

Advanced Generic Number Translation:

To translate other aspects of the Generic Number such as Nature Of Address and Numbering Plan, right click on the Translation Entry just created and select New Advanced Generic Number Translation. A screen like below will appear.

Re-Run Option:

The Generic Number Parameter was added to the Re-Run Option within the Incoming/Outgoing Translation Table entry object. By adding the Generic Number Parameter the IMG can first match and translate a Dialed or Originating Number. Once this is accomplished and the Re-Run Option is set to ‘Generic Number’, the IMG will then search the translation table entries for another entry with the ‘String to Match’ field set to ‘Generic Number’. Once it finds the correct entry, the Generic Number is then translated again to a Dialed Number, Originating Number, Generic Number, Billing Number, Info Digits, or Carrier Number.

• Create a Translation Entry by following procedure above except leave the String to Match as either Dialed Number or Originating Number and select Generic Number from the Re-Run Option field. See screen capture below.
  
  

• Create a second Translation Entry with the String to match set to ‘Generic Number’. With the rerun option configured in the first Translation Entry set to Generic Number, the IMG will find this entry. Once the entry is found the IMG will do whatever the second Translation Entry instructs it to do. In this example, the second entry will match the Generic Number of 555& and translate it to 999&. See screen capture below displaying the second translation entry.
  
  

• Once the Translation Table and its entries have been created, they can now be inserted into an ISDN Channel Group. Open the ISDN Channel Group created earlier in this document and select the Translation table just created from the Incoming Translation table fields drop down menu. See screen capture below.
  
  

• Above is a very basic example of using the Re-Route Option with the Generic Number Translation Parameter. There are many other ways to use this functionality. This procedure is created to explain the basics on how the Re-Route Option can be utilized with the Generic Number Parameter.

• Below is screen shot of the tree in ClientView after configuring the Generic Number Translation feature.
  
  

Additional Information:

• The Generic Number Parameter is present only in SS7 IAM message.

• The version of GCEMS software and version of IMG system software must both support the Generic Number Parameter feature. If versions of GCEMS are not compatible, the Translation Table elements may be incorrectly interpreted or table download may be rejected.

• A second compatibility issue exists where a configuration file created from a GCEMS which is not compatible (earlier version) is used with a version of GCEMS that has the feature in it. The incompatible GCEMS will not recognize the format of the Incoming/Outgoing Translation Table.
