XE1486L
12/00
Compact 14,400 BPS Data and Fax Modem
Description
Xecom's XE1486L combines 14,400 BPS data and
Group III send/receive fax in a compact component.
Xecom designed the XE1486L to be embedded by OEM
designers. Xecom also offers pin compatible 2400 BPS,
33,600 BPS and 56 KBPS alternatives to the XE1486L
for applications with other date rate requirements.
The XE1486L is not a modem chip but a complete
modem including the telephone interface integrated into
a compact module. It provides user transferable FCC
Part 68 registration and can connect directly to the
telephone line through an RJ11 jack. The modem
connects to the host through a TTL level serial interface.
The XE1486L also includes MNP2-4, MNP10 and
V.42 error control and MNP5 and V.42bis data
compression to provide an error free connection with the
greatest possible data throughput rate.
