What is ISDN over IP?
When you use a carrier's ISDN network the calls are in effect connected together on a point-to-point circuits. The calls are transparent (you can send any kind of traffic voice or data) and they are clocked or synchronised.
A packet network has very different characteristics. As the name says it is packet-based, all traffic goes over common cables and importantly there are no clocks. In addition, the ISDN network delivers data at a steady pre-defined rate whereas a packet network has "jitter".
The PacketBand, uniquely, over-comes all of these issues to turn a packet network into a virtual ISDN network. Any data can be transported. Calls can, if wished, be completely dynamic and be placed between any location, cleared and another site dialled. Clocks are synchronised so all interfaces are clock-locked, even when calls are cleared and remade to different sites.
Idea for all applications, particularly synchronous applications like videoconferencing, codecs, encryptors but also useful for faxes and modems. Plus it gives great PCM toll-quality very low-latency voice connections.
In fact it performs just like the traditional carrier-delivered ISDN but using low-cost packet networks.
PacketBands connected to the packet network and the ISDN PSTN provide users with break-out ability so they can still call anyone anywhere in the world as well as be called.
A great migration tool for carriers and corporates alike. |
