ISDN Network & Equipment

IS IT POSSIBLE TO USE ISDN OVER AN IP NETWORK?

Despite the rumors of IP-based networking and communications equipment declining, legacy products will be with us for a long time. Many products were based on a network of ISDN with BRI or PRI interfaces. Some of these products include video conferencing, encryption, point of sale, telemetry, PBX, and fax machines.

Connecting legacy ISDN equipment to your existing IP network would save money. The cost savings obtained by using legacy equipment cannot be ignored, especially when you are trying to solve simple networking problems requiring limited features. Moving to a newer IP-based solution may increase features you don't need and the cost rises dramatically.

Introducing the PacketBand ISDN over IP network appliance. The PacketBand appliance delivers transparent switched ISDN services across packet networks. All ports are synchronized with central, or network clocks, providing a fully clock-locked environment across asynchronous packet networks - no there is no data loss due to free-running and slipping clocks. This system provides ISDN over Ethernet/IP networks for both voice and, more critically, data applications.

The PacketBand-ISDN Network model provides an important and unique method for transporting ISDN traffic across packet networks. For some types of devices, it is the only reliable and error-free solution.

ISDN networks from carriers deliver clocked transparent 64k channels which can transport any type of traffic anywhere in the world; PacketBand does the same. ISDN "B" channels are set up dynamically across the packet network giving inter-connectivity between any device, and can "break out" into the global ISDN PSTN, accessing any other device worldwide.

All PacketBands are locked and synchronized to the network clock via an advanced clock-recovery system ensuring reliable slip-free services for all applications. This means not only can high-quality voice be transported over low-cost packet networks using existing PBXs, but so can synchronous applications such as videoconference units, voice codecs, encryptors, fax machines, PoS terminals, etc.

Not only does PacketBand deliver high-quality clock-locked transparent channels as and when needed, but it also has great flexibility in terms of adding CLIs for billing, converting numbers, and alternate routing and resiliency options.

For larger networks a low-cost SIP Server solution is available. If you are a carrier looking to deliver reliable ISDN equipment to customers, a military, governmental, or broadcast organization needing to transport or distribute synchronous ISDN, or perhaps in another vertical or a corporate with some specific ISDN/IP issues, PacketBand may be able to assist.
