SS7 Link Set

One or more Signaling Links between a Signaling Point (SP) or Signaling Transfer Point (STP) are identified as a Signaling Link Set. Link Sets provide a level of Redundancy and load sharing between two signaling nodes. The Signaling Link Set object identifies a link set that is used to connect an SS7 stack on the 2020 IMG to an adjacent point code in an SS7 network. The SS7 Link Set object is created under the SS7 Stack object.

Maximum Objects

Up to 128 Link Sets per 2020 IMG Node. This is the maximum number of links that can be created on one 2020 IMG if one signaling link per signaling link set is configured.


Related Topics and Dependencies

The SS7 Signaling Link Set object is configured under the SS7 Stack. The (Adjacent Point Code) APC determines which entity such as a Signaling Point or Signaling Transfer Point to send the ISUP information to. Once the Link Set object is created, the SS7 Signaling Link and SS7 Signaling Route can be configured under it. See links below

Field Descriptions

Link Set ID

The Link Set ID field specifies the ID of the SS7 link set. The ID's are automatically populated with the next available ID. The SS7 Link Set ID can be modified by selecting a different ID from the drop down menu. Link Set ID's range from 0-127.


APC (Adjacent Point Code)

The APC field specifies the adjacent point code of the node that this link set will be communicating with. The format of the APC will follow the same rules that the SS7 stack follows. For example if the OPC is ITU 97, which follows the format of 3-8-3, the APC should also be running ITU 97 and should follow the format of 3-8-3. Point codes are expressed in dotted decimal format. The default format is dotted decimal.
