Unique ISDN over IP products from Patapsco

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.

VoIP equipment do what they say; "Voice over IP". They convert voice to packets and transport this data across a network and then de-packetise it at the other end. they also generally compress the traffic.

The differences between a VoIP solution and PacketBand are many. The most significant ones are:

A VoIP unit can communicate across the public Internet to any other VoIP phone; the PacketBand is a 2-ended solution that resides at the edges of private networks (although it does also work across the Internet between two PacketBands).

A VoIP system is not clocked so calls between devices are not synchronised or locked. This causes data loss which is not necessarily so important for voice (although we have all experienced poor voice calls over VoIP), but it is critical for many data applications.

PacketBands are synchronised and there is no loss of voice/data because of clock slips or incompatibilities. For example video conference calls using multiple BRI ports can be placed across packet networks and then break-out into the PSTN.

PacketBands will transport any type of traffic.

PacketBands also transport signaling end-to-end and by way of an example, supports UUS-3 (User to User Signaling).

Typically in the following scenarios:

Where you need to transport synchronous data traffic across a packet network. This includes video, encryptors, codecs, faxes and modem traffic;

Where you have control over the end-points, such as in a private network or across the Internet between known destinations;

Where you need excellent quality voice with low latency and no clock slips/hits;

Where you have traditional PBXs and want to use your corporate packet network for high quality voice and other non-voice applications

Where you need to migrate customers from a traditional ISDN network to a packet network and you have no control over what they connect. Plus where you do not want the Technical support problems associated with a migration which is CPE dependant.

Where you need to extend ISDN services across a LAN or WAN;

Where ISDN cabling and distances cause you problems and costs and you would rather just plug your ISDN traffic, such as videoconferencing units, into your structured cabling

PacketBand also has extremely flexible routing, resiliency and number manipulation capabilities and special security features.

You will be surprised at the PacketBand's abilities and the number of ways it can be implemented and used. call us to discuss your ideas and applications.
