AddLLCCard

Type

SwitchKit API message

Overview

Use the SK_AddLLCCard message as an external application connected to the LLC. This message opens sockets to the SS7 cards on the node and sets up routing to the SS7 card.

AddLLCCard is used to create and connect pairs of card level device to the LLC. It has the ability to accommodate various card types including SS7 TCAP. Additional routing ID’s can be added to the same connection by sending multiple AddLLCCard messages to the same IP pair and specifying a different Routing ID. By setting the action field to 0x01 (Remove Connection), it is assumed that all routing IDs on this connection will no longer be used and will therefore be removed by the LLC. For an application to maintain communication to the card, there must always be at least one routing ID configured for that IP pair.

This message cannot be used in a SwitchManager configuration file. Instead use the Add SS7TCAPCard message.SwitchManager will generate the appropriate AddLLCCard messages for you.

AddLLCCardAck

The LLC will acknowledge AddLLCCard messages with an AddLLCCardAck message.

AddLLCCardAck( Status= <*Response Value>,

RoutingID= < Unique ID for Card Pair Added>,

Reserved1= <Not currently used>);

Status field

Possible Response Values found in the status field of an AddLLCCardAck message.

RoutingID Macros

To avoid duplicate values, the routing ID for each type of sub-component card must be derived using that cards corresponding get_RoutingID macro. Macros will be defined within SK_API.h so that they are globally accessible.

Macros available for deriving RoutingID’s.
