Abstract:
This is the fourth quarterly report on the Digital Interface Code Converter program. The purpose of this program is to design, develop, and fabricate one exploratory development model of the code converter. The code converter interfaces two PCM multiplexers which utilize different companding characteristics, bit rates, synchronization code formats and signaling formats. During this quarter work was concentrated on fabrication and testing of the exploratory development model. Changes were implemented to allow laboratory testing of alternate mappings and to allow interfacing of different multiplexers via ROM selection. Signaling information conversion between E and M signaling formats and tone signaling formats was investigated. Proper operation of the code converter was demonstrated in preliminary tests. Author
