	digital signal X - a Whatis.com definition
		Digital signal X is a term for the series of standard digital transmission rates or levels based on DS0, a transmission rate of 64 kilobits per second (Kbps), the bandwidth normally used for one telephone voice channel.
		DS0 is the base for the digital signal X series.
		DS1, used as the signal in the T1 carrier, is 24 DS0 (64 Kbps) signals transmitted using pulse-code modulation (PCM) and time-division multiplexing (TDM).

	Digital signal 0 : DS0
		Digital signal 0 (DS0): In T-carrier, a basic digital signaling rate of 64 kb/s, corresponding to the capacity of one voice-frequency[?]-equivalent channel.
		Note 1: The DS0 rate forms the basis for the North American digital multiplex transmission hierarchy.
		Note 2: The DS0 rate may support twenty 2.4-kb/s channels, or ten 4.8-kb/s channels, or five 9.67-kb/s channels, or one 56-kb/s channel, or one 64-kb/s clear channel.

	DS0 (Site not responding. Last check: 2007-10-18)
		The DS0 is the basic level of communication upon which all the other Digital Signalling levels (DS1, DS2, DS3 etc.) are built.
		A DS0, being digital, is not actually part of the loop because it is on what is referred to as the trunk side of a Digital Cross Connect Switch (DCCS).
		This is changing, but not because the telephone system is changing, but because users are purchasing equipment that utilizes what is called IP Telephony which encodes both data and voice into a single multiplexed communications path.

	T1
		Including several DS0 channels in one TDM bit stream requires the addition of framing bits, so the individual channels can be identified on recovery.
		The pattern was so simple that putting a 1 KHz tone (the standard Bell test frequency) on one of the DS0 channels would cause the circuitry to synchronize on the wrong bit.
		If a T1 formatted bit stream does not represent 24 DS0 channels, then there is no need to do anything funny with one of the bits from each channel every sixth frame.

	DS0 Server Product Description (Site not responding. Last check: 2007-10-18)
		PCSI is currently developing the DS0 Streaming Server to provide the capability to access any of the 512 DS0 timeslots within 16 E1 lines on multiple networked desktop computers.
		The DS0 Streaming Server extracts all of the DS0 timeslots from 16 separate E1 streams, and stores the information into local memory.
		The DS0 Server can stream the complete timeslot contents from a single channel, or from a set of strapped channels within a single E1, or even the contents of a set of strapped channels multiplexed across several E1s.
