ATM25

From Wikipedia, the free encyclopedia

ATM25 is an ATM (Asynchronous Transfer Mode) version wherein data is transferred at 25.6 Mbit/s, considerably slower than the 155 Mbit/s originally planned for ATM. ATM25 has no particular distinctions from other ATM versions. However, ATM25 chipsets are inexpensive in comparison to faster ATM chipsets, having the result of making ATM technology available for Small office/home office environments. However, these networks no longer have much potential for expansion, as Ethernet has become the first choice in this domain.

The WLAN connection of ATM25 systems often takes place over a fast DSL variant such as RADSL. DSL is often considered in this case, as its' technology is based on an ATM core.
