The MARBEN™ Signaling Controller mainly offers a set of standardized procedures leading to the setup and teardown of calls and connections. It invokes services from the Routing Controller and the Link Resource manager to achieve such a goal.

More precisely the MARBEN™ Signaling Controller supports the following procedures:

• Call and connection setup, modification (including rerouting) and teardown,
• Independent (i.e., without any associated connection) call setup and teardown,
• Call/connection setup crankback,
• Make-before-break connection rerouting,
• End-to-end full and preplanned rerouting,
• Inter-area routing using loose hops and exclude route.

Both unidirectional and bidirectional connections are supported. Note that call management is either handled in conformance with the OIF/ITU-T specifications or in conformance with the IETF specifications.

Hereafter the interactions between the signaling controllers and the external component for the call connection setup at the ingress Node:
