Page 16 NAMPS telephones. But one thing remained constant, there were 21 control channels for each carrier. In 1992, when Motorola tested its TDMA digi- tal product, digitizing three communication links on each of 395 voice channels, one thing remained constant: there were still 21 con- trol channels for each carrier.
