MD-IWF Options Elements

Table 5-1 describes the fields on the MD-IWF Options page.

Table 5-1 MD-IWF Options Elements

Field (* indicates a required field) Description Data Input Notes
*Diameter Response Timeout

Timeout value, in seconds, to use when sending a Diameter Request message to the Diameter network (through DM-IWF) and waiting for the Diameter Answer message to arrive. It is suggested that this timer be greater than the Diameter Routing Function's Transaction Lifetime configured under Diameter > Configuration > Routing Option Sets.

Note:

If the Diameter Pending Answer Timer is less than this value, the Diameter Error Responses from the DSR will be seen.

Format: text box; numeric

Range: 3-30

Default: 15

*MAP Response Timeout Timeout value, in seconds, to use when sending a MAP Request message to the SS7 network and waiting for the MAP Response message to arrive. This is the time from begin-dialog to close-dialog; it controls how long all of the dialogs within a transaction can continue until the dialog times out. It is suggested that this timer shall be greater than the Segmentation/Reassembly timeout value configured under the SCCP Options folder.

Format: text box; numeric

Range: 5-30

Default: 15

EIR Host Name When translating an incoming MAP-CheckIMEI (EIR) Request message to a Diameter Request message, the Destination-Host AVP will be populated with this FQDN value when the GTA that is derived from the SCCP Called Party Address cannot be mapped to a Diameter Host/Realm using Diameter Identity - GTA entries. If this value is not configured, then an error response is sent back to the SS7 network.

Format: text box

FQDN is a case-insensitive string consisting of a list of labels separated by dots, where a label may contain letters, digits, dashes (-) and underscore (_). A label must start with a letter, digit or underscore and must end with a letter or digit. Underscores may be used only as the first character. A label must be at most 63 characters long and a FQDN must be at most 255 characters long.

Range: a valid FQDN or empty

Default: N/A

EIR Realm When translating an incoming MAP-CheckIMEI (EIR) Request message to a Diameter Request message, the Destination-Realm AVP will be populated with this value when the GTA that is derived from the SCCP Called Party Address cannot be mapped to a Diameter Host/Realm using Diameter Identity - GTA entries. If this value is not configured, then an error response is sent back to the SS7 network.

Format: text box

Realm is a case-insensitive string consisting of a list of labels separated by dots, where a label may contain letters, digits, dashes (-) and underscore (_). A label must start with a letter, digit or underscore and must end with a letter or digit. Underscores may be used only as the first character. A label must be at most 63 characters long and a FQDN must be at most 255 characters long.

Range: a valid Realm or empty

Default: N/A

EIR Destination GTA When translating an incoming ECR (ME-Identity-Check) Diameter Request message to a MAP Request message, if the Destination-Host AVP is absent in the ECR message, then the SCCP Called Party GTA will be populated with this value when the ECR Request Message with no Dest-Host AVP option is configured as Translate Using EIR Dest GTA.

Format: text box; numeric

Range: a valid Global Title Address in E.164 format, or empty

Default: N/A

IWF HSS Destination Host When translating an incoming (non-EIR) MAP Request message to a Diameter Request message, the Destination-Host AVP will be populated with this FQDN value when the GTA that is derived from the SCCP Called Party Address cannot be mapped to a Diameter Host/Realm using Diameter Identity - GTA entries. If this value is not configured, then MD-IWF will not populate the Destination-Host AVP; it could be resolved on the DSR by FABR or RBAR, or by another upstream Peer.

Format: text box

FQDN is a case-insensitive string consisting of a list of labels separated by dots, where a label may contain letters, digits, dashes (-) and underscore (_). A label must start with a letter, digit or underscore and must end with a letter or digit. Underscores may be used only as the first character. A label must be at most 63 characters long and a FQDN must be at most 255 characters long.

Range: a valid FQDN or empty

Default: N/A

IWF HSS Destination Realm When translating an incoming (non-EIR) MAP Request message to a Diameter Request message, the Destination-Realm AVP will be populated with this value when the GTA that is derived from the SCCP Called Party Address cannot be mapped to a Diameter Host/Realm using Diameter Identity - GTA entries. If this value is not configured, then an error response is sent back to the SS7 network.

Format: text box Realm is a case-insensitive string consisting of a list of labels separated by dots, where a label may contain letters, digits, dashes (-) and underscore (_). A label must start with a letter, digit or underscore and must end with a letter or digit. Underscores may be used only as the first character. A label must be at most 63 characters long and a FQDN must be at most 255 characters long.

Range: a valid Realm or empty

Default: N/A

*Shutdown Mode Allows the operator to specify the shutdown method used when the Admin State is changed to Disabled. The application can be disabled using either a graceful or forced shutdown method. Graceful allows in-process transactions to continue for a configurable time period before disabling. Forced is an immediate shutdown.

Format: radio buttons

Range: Forced or Graceful

*Shutdown Timer Number of seconds that the Shutdown Timer will run during a Graceful shutdown.

Format: text box, numeric

Range: 1-30

Default: 15

ECR Request Message with no Destination Host AVP
Action
When translating an incoming ECR (ME-Identity-Check) Diameter Request message to a MAP Request message, this indicates the action to take if the Destination-Host AVP is absent in the ECR message. If the Destination-Host AVP is present, it is used in the translation to derive the SCCP Called Party GTA.
  • Discard: The Diameter to MAP transaction is discarded; a Diameter Answer message is NOT sent back to the Diameter network.
  • Send Answer: A Diameter Answer message with Experimental- Result AVP or Result-Code is sent back to the Diameter network.
  • Translate Using EIR: Translate the ECR message to a MAP Request message using the configured EIR Destination GTA as the SCCP Called Party GTA.

Format: radio buttons

Range: Discard, Send Answer, Translate using EIR

Response Result Code AVP If the configured Action is Send Answer, this value is used in the Result-Code or Experimental-Result AVP of the Diameter Answer message

Format: text box, 4-digit numeric; or pulldown list of known Result Codes

Range: 1000-5999

Response Vendor ID If zero, then a Result-Code AVP will be sent when the DSR Application is not Available. If non-zero, then an Experimental-Result AVP will be sent will the Vendor-Id AVP set to this value. Available when Send Answer is selected for the Action.

Format: text box; numeric

Range: 0-4294967295

Response Error String If a non-empty string, this configured string will be appended to the Error-Message AVP that is sent in the Diameter Answer message. Available when Send Answer is selected for the Unavailable Action field.

Format: text box; string of printable ASCII characters.

Range 0-64 characters

ECR Request Message with Dest-Host present but Not Found in mapping table
Action
When translating an incoming ECR (ME-Identity-Check) Diameter Request message to a MAP Request message, this indicates the action to take if the Destination-Host AVP is absent in the ECR message. If the Destination-Host AVP is present, it is used in the translation to derive the SCCP Called Party GTA.
  • Discard: The Diameter to MAP transaction is discarded; a Diameter Answer message is NOT sent back to the Diameter network.
  • Send Answer: A Diameter Answer message with Experimental- Result AVP or Result-Code is sent back to the Diameter network.
  • Translate Using EIR: Translate the ECR message to a MAP Request message using the configured EIR Destination GTA as the SCCP Called Party GTA.

Format: text box, numeric

Range 1-30

Default: 15
