	T-carrier - Wikipedia, the free encyclopedia
		Originally the T1 format carried 24 pulse-code modulated, time-division multiplexed speech signals each encoded in 64 kbit/s streams, leaving 8 kbit/s of framing information which facilitates the synchronization and demultiplexing at the receiver.
		Since each frame of a T1 is 193 bits in length (24 channels X 8 bits per channel + 1 control bit = 193 bits), 8000 frames per second is multiplied by 193 bits to yield a transfer rate of 1.544 Mbit/s (8000 X 193 = 1544000).
		Technically a DS1 is the data carried on a T1 circuit, and likewise for a DS3 and a T3, but the terms are almost always used interchangeably.

	T1
		T1 Framing Patterns ------------------- To synchronize with the bit stream, the receiver picks a random bit, and then examines every 193rd bit for the presence of the special framing pattern.
		The T1 Carrier standard specified in Bell Pub 62411 specifies minimum ones density in two ways (both minimums must be met) (a) an average ones density of not less than 12.5%, and (b) no more than 15 consecutive zeros between one bits.
		If your T1 channel is multiplexed and demux'ed by the common carrier, B8ZS can't work until all the mux'ing equipment is upgraded to understand receiving intentional bipolar violations and regenerating them at the far end.

	T1
		T1 technology is proving to be a cost-effective means of linking voice and data, both inter-office and intra-office, and serves as an alternative to high speed modems for data transport.
		T1 is a high speed digital network (1.544 mbps) developed by ATandT in 1957 and implemented in the early 1960's to support long-haul pulse-code modulation (PCM) voice transmission.
		What happens is a single T1 signal is generated using channels a and b and goes to the CO. The CO splits this into two T1 trunks one carrying channel a and the other carrying channel b.

	T1 from FOLDOC (Site not responding. Last check: 2007-11-05)
		T1 transmission uses a bipolar Return To Zero alternate mark inversion line coding scheme to keep the DC carrier component from saturating the line.
		Although some consider T1 signaling obsolete, much equipment operates at the "T1 rate" and such signals are either combined for transmission via faster circuits, or demultiplexed into 64 kilobit per second circuits for distribution to individual subscribers.
		Some newer equipment uses the two lines at half the T1 rate and in full-duplex mode; the sent and received signals are separated at each end by components collectively called a "hybrid".

	Howstuffworks "How does a T1 line work?"
		If your office has a T1 line, it means that the phone company has brought a fiber optic line into your office (a T1 line might also come in on copper).
		A T1 line might cost between $1,000 and $1,500 per month depending on who provides it and where it goes.
		The other end of the T1 line needs to be connected to a web server, and the total cost is a combination of the fee the phone company charges and the fee the ISP charges.

	T1, T-Extender T-1 repeater
		T1 modulation is designed for use with twisted pair solid wire phone cables.
		If you have a T1 CSU that is limited to 655 feet, connected to a device limited to 655 feet, and you put the T-Extender at one end, the T-Extender will drive the extra distance.
		The T1 transmitted signal is the issue addressed by the T-Extender, so in this case, the line would be error-prone or possibly only work in one direction.
