A Signalling gateway becomes at the interface between speaking (TDM) and data network (IP) uses. It serves for the signaling data which are held in all rule in the signaling system SS7 to work on at the net transition in such a way that you can be sent over the respective net (speaking or data network). This is not therefore necessarily, there signaling data in the TDM world on line-obtaining PCM channels with a firm range of 64 kBit/s to be sent and in the data network. In the data network package-obtaining by means of Internet minutes one works.
For the transmission of SS7 over IP minutes SCTP can be used.
The Signalling gateway can be used either solo, around high arising at SS7-Nachrichten instead of by means of TDM technology (e.g. EWSD) assistance of IP technology (e.g. Rout) to send, or however in connection with a Media gateway CONTROLLER in different solutions to the IP-Telefonie.
