Adding IETF M3UA and SUA Components
This section describes how to configure the components necessary to establish IP connections using M3UA or SUA associations on IPGWx signaling links. IPGWx signaling links are signaling links assigned to cards running either the SS7IPGW or IPGWI applications. The SS7IPGW application supports point-to-multipoint connectivity for ANSI networks. The IPGWI application supports point-to-multipoint connectivity for ITU networks.
The configuration of these IP connections consists of these items.
- Configure the IPGWx card with the Adding an IPGWx Card procedure. Turn the ISUP-over-IP (
ipisup
) feature with thechg-feat
command.Note:
Before turning on the ISUP-over-IP feature (ipisup
) feature, make sure you have purchased these features. If you are not sure whether you have purchased the ISUP-over-IP feature, contact your Oracle Sales Representative or Account Representative. Once a feature has been turned on with thechg-feat
command, the feature cannot be turned off. - Configure the required destination point codes - see Chapter 2, “Configuring Destination Tables,” in Database Administration - SS7 User's Guide.
- Configure the required IPGWx linksets with the Configuring an IPGWx Linkset procedure. If you wish to add a mate IPGWx linkset to another IPGWx linkset, perform the Adding a Mate IPGWx Linkset to another IPGWx Linkset procedure.
- Configure the IPGWx signaling links with the Adding an IPGWx Signaling Link procedure. If the addition of these signaling links will exceed the current number of signaling links the EAGLE is allowed to have, the Enabling the Large System # Links Controlled Feature procedure will have to be performed to increase the quantity of signaling links.
- Configure the required routes - see Chapter 3, “SS7 Configuration,” in Database Administration - SS7 User's Guide.
- IP addresses must be assigned to the IPGWx card configured in step 1 by performing theConfiguring an IP Link procedure. There are other IP link parameters that are assigned to the IPGWx card when the IPGWx card is configured. Default values are assigned to these parameters when the IPGWx card is configured. These values can be displayed by the
rtrv-ip-lnk
command. These values can be changed by performing theConfiguring an IP Link procedure. - Local IP hosts, assigned to the IP addresses assigned to step 6, must be configured in the database by performing the Adding an IP Host procedure. Verify the hosts with the
rtrv-ip-host
command. This establishes a relationship between the IP card related information and the connection related information. - When the IP cards are added to the database in step 1, there are IP parameters that control the IP stack that are assigned default values. These parameter values can be displayed by the
rtrv-ip-card
command. These values can be changed by performing the Configuring an IP Card procedure. - Static IP routes provide more flexibility in selecting the path to the remote destination and reduces the dependence on default routers. Static IP routes are provisioned by performing theAdding an IP Route procedure.
- Associations specify a connection between a local host/TCP port and a remote host/TCP port. Three types of associations can be provisioned: M2PA, M3UA, and SUA. Associations that are assigned to IPGWx signaling links must be either M3UA or SUA associations. The M3UA and SUA associations are configured by performing the Adding an M3UA or SUA Association procedure. M2PA associations that are assigned to IPLIMx signaling links are provisioned with the Adding an M2PA Association procedure inIETF M2PA Configuration Procedures. Associations can be assigned to IPSG signaling links also. These associations are configured by performing the Adding an IPSG M2PA Association or Adding an IPSG M3UA Association procedures. A number of fields in the association cannot be configured with the Adding an M3UA or SUA Association procedure and are set to default values. The values of these fields can be displayed using the
rtrv-assoc
command after theAdding an M3UA or SUA Association procedure is performed. These values can be changed by performing these procedures: Changing the Attributes of a M3UA or SUA Association, Changing the Buffer Size of a M3UA or SUA Association. Only one signaling link can be assigned to an IPGWx card. A maximum of 50 IP connections can be assigned to an IPGWx card. - When an M3UA or SUA association is added to the database, UA parameter set 10 is assigned to the association. There are 10 UA parameter sets that can be assigned to an association, but the UA parameter set assignment can be changed, using the Changing the Attributes of a M3UA or SUA Association procedure. The values assigned to each UA parameter set can be changed, except for UA parameter set 10, using the Changing a UA Parameter Set procedure.
- The application server contains a set of one to 16 associations, of which one or more is normally actively processing traffic. Application servers are configured by performing on of these procedures:
- Adding a New Association to a New Application Server
- Adding an Existing Association to a New Application Server
- Adding a New Association to an Existing Application Server
- Adding an Existing Association to an Existing Application Server
If the associations assigned to application server are M3UA associations, and the
open
parameter value for these associations isyes
, then the same UA parameter set must be assigned to all of the associations in the application server. - Routing keys specify MSU filters for the IP connection. Configure the routing keys with theAdding a Routing Key Containing an Application Server procedure.
- An internal point code can be provisioned to provide routing to an IP end office node. Configure the internal point codes by performing the Adding an End Node Internal Point Codeprocedure.
- The network appearance field identifies the SS7 network context for the message, for the purpose of logically separating the signaling traffic between the SGP (signaling gateway process) and the application server over a common SCTP (stream control transmission protocol) association. This field is contained in the DATA, DUNA, DAVA, DRST, DAUD, SCON, and DUPU messages. Network appearances are configured by performing the Adding a Network Appearance procedure.
- The EAGLE processes messages with a service information field (SIF) that is 272 bytes or smaller. The Large MSU Support for IP Signaling feature allows the EAGLE to process messages with a service indicator value of 6 to 15 and with a SIF that is larger than 272 bytes. Perform the Activating the Large MSU Support for IP Signaling Feature procedure to enable and turn on the Large MSU Support for IP Signaling feature.
