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).
