The Universal ISDN Port technology of Cologne Chip allows the construction of ISDN phones and PABXs with only one ISDN transceiver serving both ISDN line interface standards, S/T and U_pN/U_p0.

Thanks to the feature of automatic detection of the cabling type, a totally new class of system telephones has been successfully introduced to the world-market by Auerswald, a leading German PABX manufacturer. Thus, Auerswald has been able to reduce their phone models to the half and to save a great amount of logistic costs. On the consumer side, end-users enjoy greater flexibility when moving from one office to another – they can keep their phones even on another type of cabling.

Besides the use in terminal equipment, the same manufacturer presents a new series of modular PABX systems at CeBIT 2007. It is also using Cologne’s Universal ISDN Port approach for line cards: Users can easily convert S/T ports into U_pN/U_p0 ports by installing a tiny Coding Plug.

All new products mentioned are based on the XHFC Series of Cologne Chip.

With XHFC chip family, Cologne Chip introduces its latest development: The successful ISDN HDLC FIFO Controllers (HFC Series) have been eXtended and once more been improved. The chips of XHFC Series are available in four port granularities from 1 up to 4 ISDN interfaces. The line interface mode for each port can be selected independently (TE mode or NT mode).

These components are perfectly suitable for almost all ISDN Basic Rate applications: from price sensitive single-port applications as terminal equipment (e.g. telephones) to sophisticated multi-port applications like VoIP gateways, IP Centrex and PABXs.

More information upon these new ISDN transceivers is available here.

An outstanding member of the new chip family is XHFC-2SU. This ISDN transceiver IC offers two ISDN S/T or U_pN/U_p0 Basic Rate Interfaces. Disposing of an ideal port granularity, XHFC-2SU is the most cost-effective solution for xDSL VoIP routers with ISDN connectivity.

After three years of transition, Cologne Chip has successfully shifted its production to green ICs: All Cologne Chip parts of the current portfolio are available in a RoHS compliant version. Thanks to a common effort with our customers, the compelling deadline of July 1^st, 2006 of European Directive 2002/95/EC can be faced well-prepared.

Cologne Chip is proud to be known as a reliable partner for over 10 years: The company has been founded in 1994 and started its operation in 1995. Since then, the number of satisfied customers continously increased.

A decade of successful chip design has lead to the fact that there is no 'ISDN country' in the world where one cannot find chips with stylized Cologne Cathedral on it. Also have a glance at the company's history.

Manufacturers of electronic components are requested to convert production to lead free processes, as environmental EU legislation sets a deadline of July 1st, 2006. Cologne Chip enables its customers to smoothly convert to a green production by offering lead free ICs at the earliest convenience.
All current products are expected to be available as lead-free within this year.

Analog functions can now be implemented in pure digital logic: DIGICC Technology is an innovative design approach, enabling hardware eingineers to facilitate their design process.

Cologne Chip IP Cores (C3IP) are DIGICC based and available for various demands of ASIC projects:

- G.711/G.712 CODECs,
- ISDN Line Interfaces and
- PLLs.

This innovative technology is silicon-proven as it is successfully in the field as part of Cologne's HFC and XHFC series.

Cologne's reliable ISDN S/T interface becomes capable of ISDN U_p now: S/T interface and U_p interface are integrated into the same transceiver.

The "Universal ISDN Port" technology is perfectly suited for PABX applications and all other ISDN applications requiring both interfaces: S/T and U_p. A brief overview of this innovative interface design can be downloaded here (pdf file).

The operational mode of the ISDN interface is determined by hardware design. Besides the dedicated usage of an external circuitry for either S/T or alternatively U_p mode, there is also a third external circuitry design possible. This combined circuitry enables end users to select between both interface modes. Please click here for a short presentation (pdf file).

The "Universal ISDN Port" will become part of all future ISDN ICs of Cologne Chip.

Despite a deflating IT market over the year 2003 Cologne Chip has achieved more than satisfactory results. Continously fruitful partnerships as well as attractive new customers have contributed to a solid business development. The successful launch of the new chip family (HFC-4S, HFC-8S and HFC-E1) has given rise to a keen demand, underlining the importance of highly integrated ISDN technology on the world market.

For 2004 the management of Cologne Chip expects to continously extend the company's standing on the market of ISDN.
