Concord Data Systems’ UK distributor Dacom Systems of Milton Keynes is now selling the CDS V32 trellis modem from the Marlboro, Massachusetts company in the UK at UKP2,895: the product, running at 4,800 or 9,600bps over dial-up and leased lines, uses the trellis coded modulation technique, which Dacom claims reduces errors by a ratio of about 1,000 to one by greatly improving the signal-to-noise ratio.
