ABSTRACT:
A facility for establishing a signaling link over a telecommunications network connection formed by a number of network switches is provided so that an upstream switch may communicate with a downstream switch in the connection. The facility is particularly useful in controlling the number of times that signals traveling over the connection are subjected to a particular function.
