Neither of these technologies could communicate with each other at anything faster than 33.6Kbps. Therefore, modems based on different types of technology will now be able to communicate and exchange data. The V.90 modem standard was approved in September 1998 by the International Telecommunications Union, a specialized agency of the United Nations responsible for coordinating, regulating, and standardizing global telecommunications standards. Lucent was one of the leading contributors to the V.90 specification. Interoperability V.90 will finally allow you to connect to any ISP that has V.90 interoperable modems.
Interoperability is a key factor that enables different modem brands to connect.
Lucent based V.90 modems will continue to support K56flex, so if your ISP has not upgraded yet, you can still get a high-speed Internet connection. The majority of client modem manufacturers and head-end Internet equipment manufacturers will make the V.90 software upgrade available to their customers as soon as it is available. As the ISPs upgrade their equipment to V.90, K56flex will play an important role during this transition. K56flex, which is currently deployed by many ISPs throughout the world, will allow Internet users to access the web at the fastest possible rate even after the V.90 standard is finalized.
