By stretching the neck the stiffness that can cause aches and pains and lead to further inflammation can be relieved, often resulting in the improvement of the symptoms associated with a pinched nerve.
CDCSS or Digital Code Squelch (DCS) is a further development of the continuous tone-coded squelch system or CTCSS that uses a slow-speed, binary data stream passed as sub-audible data along with the transmission. Motorola calls this Digital Private Line or DPL.
Another outstanding difference between SCADA and DCS is that the former maintains a database of previous good values and secure data and control whenever there are slow and undependable communications, which makes it fast for urgent operator display.
