Introduction
The DSP1648C, host-accelerated modem chip is an
exciting new upgrade to Agere Systems Inc. line of
host-based controller modems. The DSP1648C
upgrades the technologies found in the DSP1648
V.90 modem solution to the new ITU-T
recommendations V.92 and V.44 communication
industry standards. V.92 and V.44 have four innova-
tive features, designed to improve modem perfor-
mance in the internet environment. The new features
are as follows:
Modem fast connect: faster start-up times.
Modem on hold
: switch between modem and an
incoming phone call without losing the data
connection.
PCM upstream: send data to central site at rates
approaching 48 kbits/s.
Data compression enhancement focused on
todays internet traffic.
The DSP1648C has an integrated PCI interface,
which eliminates the 16550 UART bottleneck found
in traditional hardware modems. The PCI interface
supports both slave and master operations while pro-
viding greater access to host PC system resources.
Host-based controller modems have the benefit of
using powerful CPUs and accessing their plentiful
RAM and disk space. Modem firmware can therefore
be updated in the field since the code simply resides
on the disk.
With this feature set, designers can create full-fea-
®
4.0,
tured modem solutions which are characterized by
low-cost, low power consumption, and high-perfor-
mance.
* Due to FCC limitations, speeds of 53 kbits/s are the maximum
permissible transmit power levels during download transmis-
sion. Actual data speeds will vary depending on the line
conditions.
† Modem on hold functionality requires call waiting services.
