Telecoms engineering company, Patapsco Communications, has launched PacketBand ISDN, said to be the first Pseudo-Wire1 product to offer clear-channel ISDN tunnelling, so allowing users to run switched and dynamic ISDN services over an IP/MPLS network.
PacketBand ISDN is said to offer opportunities to transport high value, high margin services over standard IP networks. It allows on-demand synchronous services to run over IP, whilst preserving the B channels and all the signalling and data performance characteristics required by ISDN.
PacketBand places individual calls across an IP network on-demand, with the added ability to break-out into national or international ISDN networks, opening application and service opportunities. PacketBand also supports non-switch T1/E1 TDM over IP Pseudo-Wires and also offers opportunities for voice traffic which is sensitive to quality and or delay.
Contrary to rumours of its imminent decline, Ovum estimates that by 2008 worldwide businesses will still be using 15 million basic rate ISDN services and two million primary rate ISDN services. Many of these will be serving legacy applications and terminal equipment such as non-router based applications, Group 4 fax machines, secure terminals, backup equipment and PBXs.
PacketBand ISDN enables these legacy applications to be retained and transported over an IP network, instead of over expensive ISDN switched circuits.
