Prerequisites
Before configuration can begin you must acquire the Originating Point Code (OPC) and Adjacent Point Code (APC) for the stack being configured. Once these Point Codes have been acquired the configuration can begin.
In order to create links and CIC's the IMG must have spans configured on it. Assign and configure spans on the IMG.
When configuring span profiles configure them as Clear Channel which is what the spans will need to be configured as in order to configure SS7 signaling.
See the Topics Below on how to configure Spans on the IMG
Steps
Creating an SS7 Signaling Entry
The first step to creating SS7 Signaling etc is to configure a signaling entry. The signaling entry will enable you to configure different types of signaling protocols such as SS7, SIP, ISDN, and H.323. To create the Signaling entry, right-click on the Physical IMG object (appears in the tree as the Name of the IMG) and select New Signaling. A Signaling object will get created. Commit the current object.
Now create an SS7 Signaling Object below the main signaling object. To create the SS7 signaling object, right-click on the Signaling object created and select New SS7.
The Redundancy Configuration Field in this object is defaulted to Standalone.
If not configuring redundant SS7 nodes leave the Redundancy Configuration field at Standalone. The Peer Logical Node ID field does not apply in this situation.
If configuring redundant SS7 nodes see IMG 1010 - Configuring SS7 Redundancy - 10.5.1.
Configuring SS7 Signaling Stacks
Under the SS7 Standalone object is where the SS7 signaling stack objects will be created. Right-click the SS7 Standalone object and select New SS7 Stack.
The SS7 Stack object will appear.
The Stack ID field is automatically populated with the next available number (0-3).
In Software 10.5.0+up to (16) SS7 stacks can be created per GCEMS. However, only 4 signaling stacks can be created under each IMG Logical Group. In software 10.5.3 SP7 the number of stacks that can be created in through GCEMS was increased to (32).
Note on SS7 Functionality on the IMG 1004: With each new software release Dialogic has added new SS7 functionality to the IMG 1004. See timeline below:
• Release 10.5.1 – Ability to act as a remote SS7 node and terminate up to four links. (F-1406)
• Release 10.5.3 – Full SS7 functionality. (F-1446)
Information on each individual field in the SS7 Stack 0 pane are explained in the IMG 1010 - SS7 Stack document.
Configuring multiple signaling stacks allows the IMG to interface with multiple SS7 networks. Signaling stacks are automatically assigned to SS7 objects (links, link sets, routes) as each object is configured.
Configuring SS7 Signaling Link Set
Overview on Signaling Link Sets
A "signaling link set" is an abstract path between the IMG and an APC (Adjacent Point Code). Within each linkset multiple physical signaling links are added. The same signaling stack must be assigned to all links in a link set. A typical configuration consists of two link sets.
Signaling links in a link set are “load sharing” that is, signaling traffic is distributed equally on the links to optimize efficiency.
When you configure multiple stacks, the Link Set IDs assigned to each signaling stack must be different. For example, if Link Set ID is assigned to Stack 1, it cannot also be assigned to Stack 2.
Configuring Signaling Link Sets
Right-click the desired SS7 Stack entry and select New SS7 Link Set. The SS7 Link Set pane appears.
The Link Set ID field is automatically populated with the next available number.
In the APC (Adjacent Point Code) field, enter the point code of the adjacent node to which this link set will be connected. The format of the APC will follow the same rules as that of the SS7 stack. For example if the OPC is ITU 97, which follows the format 3-8-3, the APC should also be running ITU 97 and follow the 3-8-3 format.
For more information on the individual fields of the Link Set pane see the IMG 1010 - SS7 Link Set topic
Configuring SS7 Signaling Links
Overview on Signaling Links
A "signaling link" is a point-to-point connection between two SS7 point codes (For example: An IMG and an STP). The signaling link is configured under the Signaling Link Set. The place holder assigns a physical location in the IMG (timeslot) and a previously configured Signaling Link Set to a signaling link.
When you configure multiple stacks on the IMG, the Link IDs assigned to each signaling stack must be different. For example, if Link ID:1 is assigned to Stack 1, it cannot also be assigned to Stack 2.
Configuring SS7 Signaling Links
Right-click the desired SS7 Link Set and select New SS7 Link.
The Link ID field is automatically populated with the next available number.
In the IMG field will be all the IMG's created within the IMG Logical Group. Select from drop down menu which IMG this link will be associated with
The signaling link will need to be configured on a Span/Channel. The Interface - Offset field drop-down menu will include all spans available on the IMG selected. By default the first available span is displayed. Select which span to configure the signaling link on
The Channel field has a drop down menu with all available channels on that Interface - Offset. Select a channel.
For more information on the individual fields in the SS7 Link pane see IMG 1010 - SS7 Link.
Configuring Signaling Routes
Overview on SS7 Signaling Routes
The IMG supports up to 512 routes which are identified by a Route ID.
A Destination ID defines the relationship of a signaling stack and a specific DPC (Destination Point Code)The IMG 1010 will support connecting to 128 different DPC's.
When you configure multiple SS7 stacks, the Route ID's assigned to each signaling stack must be different. For example, if Route ID:1 is assigned to Stack 1, it cannot also be assigned to Stack 2.
Configuring SS7 Signaling Routes
Right-click SS7 Link Set and select New SS7 Route.
The Route ID field is automatically populated with the next available number. The Route ID field has a drop down menu which will allow a Route ID to be selected.
The Route Type field is automatically populated with New Route. This field has a drop down menu with other selections for when configuring combined link sets. Use the default if not configuring combined link sets.
In the New DPC field, enter the DPC for this network.
For ITU, the point codes range from 0-0-0 to 7-255-7.
For ANSI, the point codes range from 0-0-0 to 255-255-255.
The Existing DPC field is automatically populated with the same value as entered in the New DPC field unless combined Link Sets are being configured. If combined link sets are being configured then the option of entering a DPC is allowed.
In the Priority field, select the priority to assign to the route when there are multiple routes to the same destination.
Use the Comments field to enter a meaningful name to identify the route.
