DCS
DCS (digital coded squelch), also known as DPL (digital private line), is a
type of subaudible signalling used for segregating groups of users. DCS
codes are identified by a three-digit octal number, which forms part of the
continuously repeating code word. When assigning DCS signalling for a
channel, you specify the three-digit code.
