small, fixed-length cells require lower processing overhead. Second, these small, fixed-length cells allow higher trans-
mission speeds than traditional packet switching methods.
ATM allocates bandwidth on demand, making it suitable for high-speed connection of voice, data, and video services.
Conventional networks carry data in a synchronous manner. Because empty slots are circulating even when the link is
not needed, network capacity is wasted. ATM automatically adjusts the network capacity to meet the system needs.

VOICE OVER DSL APPLICATION
Figure 2 shows a typical VoDSL application. The TA 544 connects to the ATM network, via a DSLAM, to provide
both voice and high speed data from a single platform.
