What does T1 line stand for?
fiber optic line
What device do you use to connect to a T1 line?
A T1 router is simply a router with the necessary interface circuitry to connect directly to a T1 line. Often, it is set up as an Internet access router to provide dedicated Internet service to an organization’s computer networks.
Is a T1 line fiber optic?
A T1 internet line is a fiber optic internet line that carries data at a moderately fast rate of 1.44 megabits per second or 192,000 bits per second. The T1 line carries data approximately 60 percent faster than a home modem can. If you use the majority of the available channels for voice, your data speed can reduce.
How many DS0 are in a T1?
24 64
Why is T1 so expensive?
One of the reasons why the T1 line cost is so high is because it offers you certain specific advantages such as the following: Guarantees on bandwidth. A high level of availability of network. Symmetric upload and download speeds.
What is the difference between a T1 and a DS1?
In colloquial terms, DS1 and T1 mean the same thing. There is a very fine point of technical difference between the two. You can get DS1 service without a T1 line but if you have a T1 line, you’ve got DS1. A T1 line multiplexes or aggregates 24 of these DS0 channels into a DS1 with a total bandwidth of 1.536 Mbps.
How many T1 are in a T3?
28 T1
Which is better T1 or T3?
A T1 line runs at a slower speed and is cheaper in cost to implement. A T3 line runs as a super fast speed but is costly to implement at a rate that can be as much as several thousand dollars more per month.
How fast was a T3 line?
44.736 Mbps
What is T1 on report card?
T1 = Term 1 (first 9 week grading period)
How many semesters are in a trimester?

What is meant by T1 2?
Half-life (symbol t1⁄2) is the time required for a quantity to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.
What is T1 and T2 in medical terms?
T1 and T2 are technical terms applied to different MRI methods used to generate magnetic resonance images. Specifically, T1 and T2 refers to the time taken between magnetic pulses and the image is taken. These different methods are used to detect different structures or chemicals in the central nervous system.
What shows up bright on T1?
T1 weighting tends to have short TE and TR times. Fat quickly realigns its longitudinal magnetization with B0, and it therefore appears bright on a T1 weighted image.
What is T1 hyperintense on MRI?
Hyperintense cerebral changes on T1-weighted images are formed due to accumulation of substances characterized by short longitudinal relaxation time including: gadolinium contrast, intra- and extracellular methemoglobin, melanin, fatty and protein-rich substances and minerals, i.a. calcium, copper and manganese.
What is a T1 hyperintense lesion?
T1 -hypointense lesions (T1-black holes) in multiple sclerosis (MS) are areas of relatively severe central nervous system (CNS) damage compared with the more non-specific T2-hyperintense lesions, which show greater signal intensity than normal brain on T2-weighted magnetic resonance imaging (MRI).
What is a T1 and T2 hyperintense lesion?
T1 lesions were defined as regions with a signal intensity similar to or reduced to the signal intensity of gray matter and corresponding to a hyperintense region on T2-weighted MRI. Hyperintense–T2 lesions were defined as sharply demarcated regions of high signal intensity compared with surrounding brain tissue.
What is the difference between T1 and T2 lesions?
When the area or “lesion” in the brain is white on T2 weighted images, this could mean the area is undergoing a temporary process like inflammation and will recover completely or the area has undergone permanent scaring. T1 lesions are black spots or “holes” observed within the white matter of the brain.
What is the difference between T1 and T2 tax return?
When you are the owner of a business, you must file a T2 corporate tax return for your incorporated business, as well as a T1 personal tax return. Your incorporated business-related income and expenses are claimed on T2; do not claim them on your T1 personal tax return.
How do I know if I have T1 or T2 MRI?
The best way to tell the two apart is to look at the grey-white matter. T1 sequences will have grey matter being darker than white matter. T2 weighted sequences, whether fluid attenuated or not, will have white matter being darker than grey matter.
