Patapsco's PacketBand-ISDN range makes available for the first time the ability for customer-premise equipment to dynamically establish clear-channel clock-locked (synchronous) ISDN calls across and through managed Ethernet/IP network. Called ISDN over IP, CESoIP or Pseudowire.
See our NEW and UPDATED web site at www.patapsco.com
A massive market for two types of IP traffic has been established over the recent few years; router traffic; and voice traffic (VoIP).
But what about all the other services that cannot use IP because of clocking issues or interfaces? Such as non-compressible ISDN data traffic for devices like secure phones, encryptors, codecs, videoconferencing, faxes or modems. Or where the quality and latency of VoIP is not acceptable? In fact any device that needs to run in a synchronous clock-locked environment.
There are many applications and services which cannot move to VoIP and which therefore do not benefit from an integrated voice & data network and the cost reductions and savings in equipment and management.
Carriers are looking at ways of delivering ISDN services to customer premises across packet networks and Patapsco has specific solutions for this application. Presenting customers with transparent services means they can connect any type of device/application and maintain high-quality low-latency voice and support issues are minimised. PacketBand also supports other ISDN applications such as UUS-3 (User to User Signaling UUS3).
See Product Datasheet.
PacketBand is designed to allow these types of services to take advantage of packet networks by delivering clear-channel ISDN over IP, or ISDN over IP Pseudo-Wires.
PacketBand-ISDN provides the ability to dynamically switch ISDN "B" channels across and through packet networks, placing calls to either a central location or any other PacketBand within the network dynamically and as-and-when needed.
With, for example a PRI PacketBand connected to a real ISDN PRI service and the packet network (acting in effect as a "gateway"), other PacketBand units on the packet network can not only dial and access each other as-and-when needed, but they can also "break-out" into the ISDN network via a "gateway" and connect to any device in the world. Or be called by them.

PacketBand is also available with BRI interfaces and you can also see a PacketBand-ISDN Product Comparison chart.
The key to this is technology is correct handling of the ISDN stacks and clocking and synchronisation. PacketBand distributes the ISDN clocks to all units so all are locked and synchronised, enabling units to communicate without slips/hits/errors and to access the real clocked ISDN network. Patapsco have been involved in developing our own ISDN protocol stacks for 15 years.
The PacketBand-ISDN-4P is available with 1 – 4 T1 and/or E1 full or fractional interfaces which can be switched between connecting to equipment or connecting to the ISDN network (NT or TE).
All ISDN PacketBands in a network are locked to one or more clock sources using an automatic clocking hierarchy and the remote units recover the clock across the Packet network to a very high accuracy and stability (examples available when you register).
In effect all ISDN PacketBands are synchronised to the same clock, and attached devices see no difference to when connected to a "real" ISDN network.
ISDN calls can be established anywhere on the IP network, or just within Closed User Groups (CUGs) using SIP or alternate methods.
PacketBand is able to manipulate dialled numbers for least cost routing or, for example, converting an emergency "112" or "911" into the full PSTN number for the regional centre.
CLIs can be added/modified, perhaps for billing purposes. In fact the PacketBand is able to switch, route, modify with a great deal of flexibility.
Not only can "legacy" ISDN equipment now take advantage of low-cost and widely available packet networks, but opportunities for significant cost reductions in non-compressible ISDN data calls are achievable, particularly for high-cost international calls.
PacketBand can connect to a variety of networks and also has Ethernet ports for connection to other local services such as routers, IP-PBXs or gateways.
