Abstract

Loops via which a signalling point communicates with itself are advantageous for solving various problems. According to the invention, a loop is enabled by a link that is returned in a loop from a signalling point to the same signalling point and to which two different signalling network identities are allocated at the output and input side.

Claims

1-10. -10. (canceled)

11. A signaling node for processing signaling messages, comprising:

(a) links via which the signaling node is connected to other signaling nodes;

(b) at least one signaling system that sends signaling messages to other signaling nodes or, respectively, receives signaling messages from said other signaling nodes, via said links;

characterized by;

(c) said signaling system respectively allocates a signaling network identity to a link;

(d) at least one link that is not connected to other signaling nodes but formed as a loop, what is referred to as a loop link;

whereby different signaling network identities are allocated to the loop link at an output and input side by the signaling system.
