  • Abstract
    The Jumbogroup Multiplex (JMX) translates basic jumbogroup signals to and from L5 line frequencies. Each of the three jumbogroups contains six mastergroups, any of which may be analog (600 voice channels) or digitally derived (13.29 Mb/s). In addition to frequency translation, the JMX provides regulation and equalization on a jumbogroup basis and automatic 1-for-1 protection. Terminal noise performance is better than 13 dBrncO, and equal level coupling loss (crosstalk loss) exceeds 90 dB.
