Apollo
3
Q:
Why is the Apollo 3 solution described as controllerless?
-
The Apollo
3 PCI NIC requires no embedded NIC processor. All controller processing
is managed by the processor on the host PC.
Q: What
additional features does the Apollo 3 have over Apollo 2?
-
The Apollo
3 chipset consists of the i90388 DMT / ATM framer device and the i80234
AFE (Analog Front End) device. The new chipset further integrates
an external PCI / Utopia interface chip into the DMT transceiver / ATM
framer device, and an analog mux (multiplexer) and line receiver with companion
filtering circuitry into the AFE device.
Q: How
does ADSL achieve high data rates?
-
ADSL
increases the bandwidth of an existing phone line by making use of unused
bandwidth. Most cable is only using 4000 Hz of cable bandwidth for transmission
of voice and modem. By using the 1.1 Megahertz bandwidth capability of
phone cable, data rates of over 8 Million bits per second (bps) are possible
(compared to the maximum rate of 56 kbps for today's V.90 modems).
