Siemens has taken an unspecified stake in Efficient Networks, which has agreed to provide the German giant with its range of digital subscriber line (DSL) adapter cards.
Siemens will include the cards in its Xpresslink range of DSL over asynchronous transfer mode (ATM) modems, which are aimed at service providers. DSL enables carriers to soup up their traditional copper networks to offer broadband networking capabilities. For example, DSL technology over copper wire enables consumers to surf the Web and talk on the telephone simultaneously.
Efficient's Speedstream DSL family includes external Ethernet attached modems, external universal serial bus modems, and internal modems and adapters for end user installation.
