Does it make sense to change TDM to IP?

alternative way of development, IP-telephony, construction of NGN

IP-technology approved by the communications market stronger with each passing year. Already no one doubts that the future belongs to IP networks that will keep pace with the ever-growing needs of network users, as opposed to TDM networks that already today are outdated. Is it possible to “painless” transition, we consider in this article.

SS7 to SIP

SS7, an individual network, telephone connection

SS7 – is an individual network, so voice and data are transmitted one-way, all the signals it sends completely different. Before there was a network of SS7, telephone connection going through the same channels on which there was talk of subscribers. The fact that the user information and signals transmitted at different times. Has contrast SS7 ISDN. The latest network subscribers and switches can send each other signaling channel D, and here in the SS7 this exchange of information is possible only between network components.

SS7 to SIP: how does it work

SS7, architecture for performing out-band signaling

SS7 is architecture for performing out-band signaling in support of the creation of call billing, routing information exchange functions of the PSTN (public switched telephone network). SS7 is what functions are executed common channel signaling network, as well as what protocols tedious for its successful execution.
