By using multicarrier modulation and PEP, the TrailBlazer could maintain high-speed connections even on poor quality phone lines that wouldn't work for normal modems. This was particularly useful on international calls.
The TrailBlazer was particularly well received by the UUCP community, because it spoofed the UUCP "g" protocol for high throughput.
The T1000 was a cost-reduced model that was limited to a maximum of 9600 bps. The T2000 was a version of the TrailBlazer supporting synchronous links.
Initially the NetBlazer only supported IP routing, but support for IPX (Novell) and AppleTalk protocols was added in the version 2 software.
Many NetBlazer models were based on PC platforms, although the NetBlazer PN family used a custom 386-based logic board in a modem case, and the NetBlazer LS family used a Motorola MC68EN360 processor in a modem case.
The T3000 modem added V.32bis support (14400 bps), and the WorldBlazer added fax support.
However, Telebit was somewhat taken by surprise by V.34 (28800 bps), and did not have a product in development soon enough to satisfy the market demand. Instead, the company executives looked for a company with V.34 technology that could be acquired.
Management claimed that the company would keep the west coast office open for NetBlazer engineering. However, as soon as the VP of Engineering resigned (spring 1994), the company announced that the west coast office would be closed.
On October 25, 1996, Telebit Corporation was acquired by Cisco Systems, Inc., although they sold part of it back to the Telebit Corporation executive staff to form a new privately held corporation named Telebit Incorporated.
On August 11, 1997 Telebit Incorporated merged with ITK Telekommunikation AG, forming ITK International, Inc.
On July 1, 1998, Digi International announced that it had signed a definitive agreement to purchase ITK International, Inc.
Digi International had no interest in the Telebit products, and has discontinued them.
