INTRODUCTION
The KS16112 and KS16114 are synchronous, half - duplex modems capable of speeds up to 9600 bps ( KS16112 ) or up to 14400 bps ( KS16114 ).
These modems satisfy the requirements specified in ITU-T recommendations V.17 ( KS16114 ), V.29, V.27 ter, V.21 Channel 2
and T.4, and meet the binary signaling requirements of T.30.
These modem devices can operate over the public switched telephone network ( PSTN ) with the addition of the appropriate data access arrangement ( DAA ).
These products are intended to be used in Group 3 facsimile machines or fax processing boards and can operate at 14400 ( KS16114 ), 12000 ( KS16114 ), 9600, 7200, 4800, 2400 or 300 bps depending on the selected configuration.
These devices also feature V.17 short train ( KS16114 ) and V.27 ter short train and three programmable tone detectors as well as a programmable DTMF receiver. Additionally, HDLC framing ( according to T.30 ) at 14400 ( KS16114 ), 12000 ( KS16114 ), 9600, 7200, 4800, 2400 or 300 bps is also featured.
