	Practical Networking: Moving to 100 Mbit/s
		However, you may not have the time or budget to migrate the entire network to 100 Mbit/s Ethernet at one time: After all, you will need to purchase and install new hubs, new network interface boards in each workstation, and maybe even new workstations to replace older ones that do not have PCI slots.
		If the existing 10 Mbit/s Ethernet hubs resided in a central location, such as in a server room, you might want to purchase and install a stackable dual-speed hub.
		When you were ready to replace a 10 Mbit/s Ethernet hub, you could simply purchase a dual-speed module with the number of ports you needed.

	Doylestown Patriot - MBIT Class of 2006 learns 'tools of the trade' (Site not responding. Last check: 2007-11-07)
		The Middle Bucks Institute of Technology (MBIT) held its Senior Awards and Recognition Ceremony last Tuesday evening in the auditorium of Archbishop Wood High School, providing 250 seniors from surrounding secondary schools with the "tools of the trade," and a head start with practical experience in their vocational career of choice.
		McCombe was handed a plaque acknowledging his role in spearheading what started as a small group of MBIT students, faculty and community volunteers and grew to a national campaign.
		Following a "Hands On USA" food prep drive, which fed 1,500 meals to displaced Biloxians back in November of 2005, the team heard the plight of teens there who lost athletic programs, afterschool jobs and upcoming memory events such as their junior and senior proms scheduled for April 22 of this year.

	Mbit / Fast Ethernet
		For applications which require a throughput higher than 20 Mbit/s, the quite expensive FDDI is one possibility and is especially recommendable for the backbone area, otherwise the solution is a 100 Mbit/s Fast Ethernet Standard.
		As for 10 Mbit/s Ethernet, 100 Mbit/s Fast Ethernet also requires a network adapter, also known as a N etwork I nterface C ard (NIC), for connecting devices (Server/Clients etc.) to the network.
		At 100 Mbit/ s this equals 5.76 microseconds, whereas at 10 Mbit/s it is 57.6 microseconds.

	Megabit per second - Wikipedia, the free encyclopedia
		A megabit per second (Mbit/s or Mbps) is a unit of data transfer rate equal to 1,000,000 bits per second or 1,000 kilobits per second.
		The bandwidths of consumer broadband internet services are often rated in Mbit/s.
		This means they can support a transfer rate of 10 or 100 or 1000 Mbit/s.

	Techworld.com - Speed-Boosted Wi-Fi isn't all that fast
		While public hotspots and most enterprise networks are still moseying along with pokey old 11 Mbit/s 802.11b Wi-Fi network cards and routers, SOHO users have moved to the faster 802.11g standard and are already being offered a new generation of products promising rip-roaring speeds of 108 Mbit/s or 125 Mbit/s.
		The 108 Mbit/s Super G technology, which came out last autumn, is based on Atheros chip sets and is used by D-Link and NetGear, among others.
		The 125 Mbit/s Afterburner vendors claim that their products are all interoperable in high-speed mode, while Super G products may not be.

	Broadband Internet Information Page - broadband-internet
		The FCC definition of broadband is 200 kbit/s (0.2 Mbit/s) in one direction, and advanced broadband is at least 200 kbit/s in both directions.
		It is widely believed Telstra limits their ADSL speed to 1.5 Mbit/s to avoid 'income substitution' as they continue to earn access fees 10-50 times higher than typical Australian ADSL service fees for older generation 'E1', 'ATM' and 'Frame Relay' services.
		Symmetric broadband Internet access of 100 Mbit/s is available for USD 54 a month, as of november 2004.

	MPEG-2 video compression
		For digital terrestrial television broadcasting of standard-definition video, a bit rate of around 6 Mbit/s is thought to be a good compromise between picture quality and transmission bandwidth efficiency.
		The bit rate overhead of using motion-compensated prediction is the need to convey the motion vectors required to predict each block to the decoder.
		For example, an MPEG-2 coder operating at 6 Mbit/s with a buffer size of 1.8 Mbits would have a total delay through the coder and decoder buffers of around 300 ms.

	SANYO > Transistors (Site not responding. Last check: 2007-11-07)
		SANYO low saturation voltage transistors adopt SANYO's unique FBET and MBIT structure technologies, and provide superlative characteristics that were not possible with earlier device structures to meet SANYO's superlative performance design goal.
		The MBIT series products, which adopt the FBET and MBIT structures, achieve a current capacity 1.5 to 2 times larger than chips of the same size with earlier device structures.
		This new structure does not simply increase the ICmax rating of the device, but achieves a 30 to 50% reduction in the saturation voltage, which is a critically important characteristic, as compared to earlier products with the same chip size.

		One of the ATM switches is connected to the ATM Pilot/network of Telefónica by means of a 155 Mbit/s interface and to the ATM network of the ETSI of Telecommunications of Madrid through a similar interface.
		In addition to the ATM 155 Mbit/s interfaces, other ATM interfaces are available, 2 Mbit/s, 34 Mbit/s, 140 Mbit/s and 622 Mbit/s, all conforming to the appropriate international standards.
		The ATM interfaces of 155 Mbit/s are supported on monomode or multimode optical fiber; those of 622 Mbit/s only on monomode fiber.

	EBU's Evaluation of DV Formats
		DV / DV-based 25 Mbit/s with a sampling structure of 4:1:1, and DV-based 50 Mbit/s with a sampling structure of 4:2:2, using fixed bit-rates and intra-frame coding techniques exclusively.
		DV-based 25 Mbit/s with a sampling structure of 4:2:0 should be confined to special applications.
		Post-production potential with 4:1:1 DV-based 25 Mbit/s compression is limited, due to the combined effects of reduced chroma-signal bandwidth and the progressive accumulation of compression artifacts.

		This is an important fuction because, once combined into a single stream, the data are in a form well suited to digital storage or transmission.
		Part 2 was developed to operate principally from storage media offering a continuous transfer rate of about 1,5 Mbit/s.
		Nevertheless it can be used more widely than this because the approach taken is generic.

		For now, "100 Mbit/s" means 100 Mbit/s downstream and 50 Mbit/s upstream, which Sekar says NTT plans to deploy starting in April.
		The U.S. might not be far behind, as Sekar claims Ikanos's VDSL2 chips have drawn the interest of a U.S. carrier that could deploy 100 Mbit/s in trials by year's end.
		That would be a surprising twist, given that U.S. DSL tends to lag Asia the way fashions in Albania lag the latest from Paris.

		Now if you have not been sleeping you will have figured out that for a T1 if you multiply 24 x DS0 (64,000) you do NOT get 1.544 Mbit/s (that would be 24 * 64,000 = 1.536 Mbit/s).
		The extra bits are lost between 'frames' where a frame consists of one 8 bit sample for each of the 24 channels (remember the DS0 basics).
		The final arithmetic is 193 bits x 8K samples = 1.544 Mbit/s.
