Some professional systems use a phase-reversal of the CTCSS tone at the end of a transmission to eliminate the squelch crash or squelch tail. This is common with General Electric Mobile Radio and Motorola systems. When the user releases the push-to-talk button the CTCSS tone does a phase shift for about 200 milliseconds.
Some DCS codes are inverted data of others: one code with the marks and spaces inverted may form a different valid DCS code (413 is equivalent to 054 inverted). Because of the use of the 136 Hz code, many receivers will decode a DCS signal when tuned to the CTCSS tone of 136.5 Hz (depending on receiver system tolerance).
As with FRS/GMRS and PMR446, the use of tone squelch systems such as CTCSS/DCS is encouraged. Like the PMR446, LPD433, Japan's 421–422 MHz SLPR service and KDR444 services, use of these frequencies in countries such as the United States is illegal without an amateur radio license as they fall within the 420–450 MHz 70 cm ham radio allocation.

Data collection system (DCS) is a computer application that facilitates the process of data collection, allowing specific, structured information to be gathered in a systematic fashion, subsequently enabling data analysis to be performed on the information.
A distributed control system (DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers ...
The DCS-3000 collects information associated with dialed and incoming numbers like traditional trap-and-trace and pen registers. The article named "Red Hook" as the client for DCS-3000. [1] Wired reported that the DCS-3000 cost $320 per number targeted, and that the software is maintained by Booz Allen Hamilton. [8]
As a result of 2005 BRAC legislation that required the bulk of enlisted technical medical training in the Army, Air Force, and Navy to be collocated to Fort Sam Houston, Texas, much of the enlisted medical training was moved from AHS to the Medical Education and Training Campus (METC). [2] The transition took place during 2010 and 2011.
