Model INT-9903

 

PCI FDM Baseband to ITU-T (CCITT) E1 Transmultiplexer

 

 

Overview

The INT-9903 transmultiplexer accepts a frequency division multiplex FDM baseband input. Thirty one embedded 4kHz wide voice grade channels (VGCs) are demultiplexed and output both as an ITU-T E1 PCM signal and as NRZ data and clock signals. Two VGCs may also be selected as analog audio outputs. Each VGC may be either upright or inverted sideband and may be located at any frequency within the baseband. The transmux is a single standard length PCI Bus printed circuit board that is compatible with many host computers and software operating systems. Multiple cards may be installed in a single host computer, limited only by the number of free PCI slots available.
