Synchronous clock-locked dynamically-dialled ISDN PRI and BRI calls over Ip and Ethernet packet networks.
The trend towards low-cost IP and Ethernet networks is building. It is ideal for router-based traffic and packet-based data protocols. And of course voice, where any delays and degradation in quality is not usually critical.
However, there are large numbers devices which cannot, until now, use Packet Networks because of clocking issues, and these are missing out on the IP cost savings.
An additional issue is many carriers are "sun-setting" ISDN and users need a migration path for their ISDN equipment, applications and infrastructure.
The type of equipment that can benefit from PacketBand-ISDN are codecs, encryptors, secure telephones (such as Brents, Elcrodats and STEs), fax machines and any other piece of existing ISDN equipment which needs a quality clocked service.
How many devices and users are missing out on low-cost IP transport? By 2008 it is expected that there will still be 2 million PRI circuits installed; 16 million BRIs; and 56 million leased lines* !
Patapsco's PacketBand family is the first equipment to supply low-cost user-premises equipment which turns a Packet Network into a virtual switched ISDN cloud. Called "Pseudo-Wires", cesoip, ISDN over IP or ISDN over ethernet, these clear-channel ISDN "B" calls open new opportunities for legacy and non-IP devices to reap the benefits of ISDN over IP pseudo wire access.
Connect to PacketBand and you can make and place clock-locked ISDN clear-channel calls across and through Metro, national and international IP and Ethernet networks,
just as if connected to a “real” ISDN network.
PacketBand delivers PRI over IP and BRI over IP where all "B" channels can inter-work.
The diagram below is a representation illustrating examples of equipment and how calls can be established across a Packet Network and breaking-out into the “real” ISDN.
PacketBand can also work over the Public Internet although there are some constraints. Please contact us for information.
Calls can be placed on-demand to other locations on the network or because everything is clock-locked, “break-out” into the local ISDN network. This means any ISDN device in the world can be connected to using the IP network or a combination of IP and ISDN.

Clocks are recovered across the network to a very high accuracy, down to 10ppb. Examples of clocks, MTIEs and TIEs are available once registered.
All devices work in a clock- locked and synchronous mode.
Whilst large cost savings are possible using ISDN over IP or ISDN over Ethernet, particularly when using the IP network for the international element and breaking-out for the last mile if needed, the most significant opportunities are in retaining existing equipment and services.
For carriers the PacketBand gives a low-cost migration that can be offered to existing ISDN users when sun-setting BRIs, providing a consistent service yet gaining the advantages of delivering IP.
PacketBand also support point-to-point Pseudo-Wires or TDM over IP logical circuits, so TDMs, legacy synchronous devices, PABXs can also use IP.

Telos customer comment ".....using this technology codecs in the IP world could "call" other IP codecs or they could place calls to ISDN codecs. For a large company with a WAN with QoS this could result in some big savings since on net access would be "free" and off net access could be aggregated to save on ISDN costs. Pretty slick, eh?"
