download or fax services using the high speed data/fax modem. The software-upgradeable
feature ensures continuous support of future ITU 56K standards as they become available.
The Data/Fax Modem is installed as a COM port and runs an extended AT command set,
and works with all major Windows Fax/Modem software. You don’t have to change your
current communications software.
The video-ready interface supplied by the CardBus 56k Modem Card provides
videoconferencing capability using traditional POTS lines.
Note:
56Kbps refers to download speed only, and requires compatible modems at both ends.
Other conditions, including telephone line quality and country specific regulation, may
limit modem speed.
56Kbps Technology
The Hypertec CardBus 56k Modem Card uses K56flex× and V.90 modem technologies to
reach speeds of up to 56Kbps over standard phone lines. This, together with downstream
speeds of up to 56Kbps provided by the
user’s Internet Service Provider (ISP) results in dramatically faster delivery of Internet
information.
The higher speeds are achieved by using only one digital-to-analog line conversion in the
connection between the user and the Internet Service Provider. This requires the ISP to
have a direct digital connection, and the modems at both ends must be compatible. Using
V.90 and K56flex× technologies, data is downloaded from the server at speeds of up to
56Kbps, while data sent upstream by the user travels at the standard V.34 maximum rate of
33.6Kbps.
