How do you turn an analog voice in digital?

In Pulse Code Modulation, how many samples are taken per second? (this was based on the Nyquist theorm that determined this was the minimum # of samples that allowed true representation of an analog signal)

After converting an analog signal to a digital one, what allows the joining of several sigital signals into one?

In the video as well as the slides, a train was used an analogy to how a T-1, multiplexed digital signal worked. A train car represented what?

How many wires are in a T-1 signal over a copper cable like shielded twisted pair (STP)?

How many frames per second are transmitted over a T-1 signal?

This early method was used to represent a T-1 signal electrically on a wire. A 'one' was represented by the presence of voltage at the time of sampling and a 'zero' was represented by no voltage. Two one's in a row would have opposite polarity (one positive voltage, the next had negative polarity). This is called:

B8ZS stands for:

With B8ZS, a bi-polar violation would indicate this:

This type of T-1 frame allows monitoring of the data stream to track error rates, as well as initiate loopbacks for testing

This device (located at a business customer location) is where analog signals are converted to digital, then placed together with 23 other signals to form a T-1, DS-1 framed signal, and vice versa at the distant end (which could be a service provider's central office location or at another customer location within the same company)

Choose all valid T-1 test patterns

A yellow alert T-1 alarm condition represents what?

When speaking about a T-1 multiplexor, the trunk side points to the _______ while the line side points toward the _______.

A T-1 signal commonly terminates on a 8-pin RM connector. That standard is a RJ-48. The transmit pair is pins ______ while the receive signal is on pins ______.

How many cities are simulated in the DMACC West Network Technology lab?

When should you register for summer classes at DMACC?
