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 i n several device models. Modem data pump and controller functions, traditionally enabled using dedicated hardware, are processed in a Pentium MMX-compatible CPU using host-signal processing modem software which is included in the SoftK56 modem. Refer to the Product Release Notice for the feature set available. In ITU-T V.90/K56flex data mode, the modem can receive data at speeds up to 56 kbps from a digitally connected V.90 or K56flex-compatible central site modem. A V.90/K56flex modem takes advantage of the PSTN which is primari ly 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 modem can transmit data at speeds up to V.34 rates. In V.34 data mode, the modem operates at li ne speeds up to 33.6 kbps. When applicable, error correction (V.42/MNP 2-4) and data compression (V.42 bis/MNP 5) maximi ze data transfer i ntegrity 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.
