8 Configuring SS7 Signaling Server Units for TDM

The following sections describe how to configure Service Broker SS7 SSUs using the Service Broker Administration Console and Java MBeans:

Configuring SS7 SSU TDM with the Administration Console
Configuring SSU SS7 TDM with Java MBeans

Configuring SS7 SSU TDM with the Administration Console

This section describes how to configure an SS7 SSU in a network in which SS7 traffic is carried over the traditional TDM. Because deployment of Service Broker involves configuration of two SSU instances, SS7 equipment connected to both instances must be configured as described in the following sections. The section provides graphical representations of deployment examples.

You can configure SS7 SSUs using the SSU SS7 TDM configuration screen.

To access the SSU SS7 TDM Configuration Page:

On the Domain Navigation pane, select OCSB > Signaling Tier > SSU SS7 TDM. The SSU SS7 TDM configuration screen is displayed in the Configuration pane.

The SSU SS7 TDM configuration screen enables you to configure parameters in tabs described in Table 8-1.

Note:

You must configure the parameters exactly in the same order as they are presented in Table 8-1.

Routing

The Routing tab enables you to define an IM to which SS7 SSU routes an incoming session by specifying a set of parameters known as incoming routing rules. For each incoming routing rule, you need to configure the following parameters:

IM to which SS7 SSU routes an incoming session
Criteria that an incoming session must meet to be routed to this IM
Priority in which SS7 SSU checks incoming routing rules to evaluate whether an incoming session fits the criteria defined in a rule. SS7 SSU applies the first found rule which criteria are met by an incoming session.

For example, if you created multiple rules for the same IM, SS7 SSU begins with the rule that has the highest priority. If an incoming session fits the criteria defined in this rule, SS7 SSU applies the rule and do not check the rest of the rules. Otherwise, SS7 SSU checks whether an incoming session fits the criteria of a rule with a lower priority. SS7 SSU performs this check until SS7 SSU finds a rule whose criteria are met by an incoming session.

You can define incoming routing rules using the Routing tab. The process of defining an incoming routing rule consists of the following steps:

You create a rule and define its name, priority, and the IM for which you are creating the rule. You perform these actions using the Incoming Routing Rules subtab.
You define criteria for each rule that you created in step 1.

Accessing the Routing Tab

The Routing tab enables you to define rules for routing incoming sessions to IMs.

To access the Routing tab:

On the Domain Navigation pane, select OCSB > Signaling Tier > SSU SS7 TDM. The SSU SS7 TDM Configuration screen is displayed.
Click the Routing tab. The Routing tab contains the subtabs described in Table 8-22.

For more information, see "Configuring Incoming Routing Criteria Parameters".

Configuring Incoming Routing Rules Parameters

The Incoming Routing Rules subtab enables you to define a name, priority, and an IM for which you create a rule. The Incoming Routing Rules subtab contains a table in which each row represents an individual rule.

When you define a rule, you need to specify the fields defined in Table 8-23.

Table 8-23 Incoming Routing Rule Fields

Name	Type	Description
Name	STRING	Specifies a unique rule name
Priority	INT	Specifies an order in which SS7 SSU checks routing rules to evaluate if an incoming session fits rule's criteria. SS7 SSU applies the first found rule which criteria are met by an incoming session. The lower the number, the higher the priority. For example, if you created two rules and set Priority of one rule to" 1" and set Priority of another rule to "2", SS7 SSU checks the rule with Priority set to "1" first. You can define an incoming routing rule that SS7 SSU applies if no other rule can be applied, by setting the Priority parameter of this rule to the largest number (that is lowest priority). There is no need to specify incoming routing criteria for such a rule.
Module Instance	STRING	Specifies the URI of an IM to which the SS7 SSU routes an incoming session. The URI has the following format: <IM-instance-name>.<IM-type>@<domain-id> <IM-instance-name>: The IM instance name that you specified when you added this IM in the IM Managment Configuration screen. <IM-type>: The type of the IM instance <domain-id>: The name of a Processing Domain or a Processing Domain Group where the relevant IM is deployed. To set a Processing Domain, you must specify the name you configured for the domain during its creation.For more information, see "Setting a Service Broker Domain Name". To set a Processing Domain Group, you must specify the group name.For more information about Processing Domain Groups, see "Managing Processing Domain Groups".

Specifies the URI of an IM to which the SS7 SSU routes an incoming session.

The URI has the following format:

<IM-instance-name>.<IM-type>@<domain-id>

<IM-instance-name>: The IM instance name that you specified when you added this IM in the IM Managment Configuration screen.
<IM-type>: The type of the IM instance
<domain-id>: The name of a Processing Domain or a Processing Domain Group where the relevant IM is deployed.

To set a Processing Domain, you must specify the name you configured for the domain during its creation.For more information, see "Setting a Service Broker Domain Name".

To set a Processing Domain Group, you must specify the group name.For more information about Processing Domain Groups, see "Managing Processing Domain Groups".

Example:

imscfcap4_instance.IMSCFCAP4@processing-domain-1

Configuring Incoming Routing Criteria Parameters

The Incoming Routing Criteria subtab enables you to define criteria for rules that you created on the Incoming Routing Rules subtab. The Incoming Routing Criteria contains a table in which each row represents a routing rule.

When you define criteria, you need to specify the fields defined in Table 8-24.

Table 8-24 Incoming Routing Criteria Fields

Name	Type	Description
Parent	STRING	Specifies the name of a rule for which you want to define criteria. This drop-down list contains names of the rules that you created on the Incoming Routing Rules subtab.
Name	STRING	Specifies a unique rule name
Session Key	STRING	Specifies a parameter inside an SCCP message based on which the SS7 SSU performs routing. The SS7 SSU will route incoming messages to a specified module instance, if the value of this parameter matches the Value field. Possible values: DEST_ADDRESS_ALIAS SOURCE_ADDRESS_ALIAS APPLICATION_CONTEXT SERVICE_KEY OPCODE
Value	STRING	Specifies a value that the Session Key parameter of an SCCP message must match, in order for the rule specified in Parent to apply. You can define one of the following in the Value parameter: Single value Range of dash-separated values Comma-separated values

Configuring SSU SS7 TDM with Java MBeans

Service Broker provides a set of MBeans that expose attributes and operations for configuring SSU SS7 TDM through JMX, shown in Figure 8-12. Because a Service Broker deployment includes two SSU instances, you need to configure an SsuTargetMBean for each SSU instance separately.

The following sections provide reference information for the SS7 SSU configuration MBeans.
