SS7 to SIP Gateway

Option 1 is used when it is required to replace the TDM Switch with the SoftSwitch. If multiple subscriber nodes are connected to the TDM Switch over the SS7 interface they can be switched to the SoftSwitch using the gateway as indicated on the following figure.

In this case the SS7 interface disconnects from the TDM Switch and connects to the gateway that is connected to the SoftSwitch via the SIP data communications network.

Option 2 is used when it is required to connect VoIP subscribers from the local network to the PSTN number capacity. If the operator has the existing TDM Switch with free SS7 interfaces the gateway on the TDM network side looks as the SS7 subscriber node while on the IP network side it looks as the IP ATE where IP subscribers register (please see the figure).
