1. INTRODUCTION
The Garnet Systems GTM-56KM6 Host Software Processed
V.90/K56flex Modem Device Family supports high speed analog data,
high speed fax operation over the PSTN world-wide and is offered in
severaldevice models.
Modemdata pump and controller functions, traditionally enabled using
dedicated hardware, are processed in a Pentium MMX-compatible
CPU using host-signal processing modemsoftware which is included in
the SoftK56 modem. Refer to the Product Release Notice for the feature
set available.
In ITU-TV.90/K56flexdata mode, the modemcan receive data at speeds
up to 56 kbps from a digitallyconnected V.90 or
K56flex-compatible central site modem. A V.90/K56flex modem takes
advantage of the PSTN which is primarily digital except
for the client modem to central office local loop and are ideal for
applications such as remote access to an Internet Service
Provider (ISP), on-line service, or corporate site. In this mode, the
modemcantransmit data at speeds up to V.34 rates.
In V.34 data mode, the modemoperates at line speeds up to 33.6 kbps.
When applicable, error correction (V.42/MNP 2-4)
and data compression (V.42 bis/MNP 5) maximize data transfer integrity
and boost average data throughput. Non-error-correcting mode is also
supported.
Fax Group 3 send and receive rates are supported up to 14.4 kbps, with
T.30 protocol.
