Model 139A FDM-to-PCM Transmultiplexer

The Model 139A FDM Transmultiplexer can be used to digitize, demodulate, demultiplex, and remultiplex FDM channels from two 20-MHz baseband inputs into TDM streams carried by up to four HDB3 E3 outputs. These outputs may be connected to the E3 inputs of any CSC-based device. The Model 139A may also supply an FDM-to-TDM case notation map that can be used by the CSC-based units for proper attachment to output SRI.

	Accepts two 0-19.75 MHz FDM basebands, each containing more than 3600 VGCs
	Built-in channel plan identification
	Demultiplexes up to 1920 voice channels taken from up to 160 FDM groups
	Outputs all 1920 channels in four E3 streams conforming to CCITT Recommendation G.751
	NPR of ~35 dB for 8-MHz noise-loaded FDM basebands
	Independent left/right headphone output
	Remote control and status sensing via Ethernet or RS232 interfaces
	1.75-inch-high rack-mount chassis, 18 lb
	85-260V AC, 47-63 Hz, 175 watts
