CIS 6 x 100Bd/120Hz VFT system

fig. 1
CIS 6x100 VFT is a variant of the CIS 3x100 waveform and consists of 6 x 100Bd channels with 120 Hz shift and 100 Baud speed, separation bewteen channels is 480 Hz (figs 2,3). Channels are arranged as in fig. 1.

This system can serve up to six outstations, in this sample only the lower channel is used (one-of-six mode) according to the needs at that time (number of the outstations to serve)  other modes are frequently observed:

in this post it has been verified that the system carries up to six T207/CIS-14 channels for a total of 12 independent 5-bit channels.
