Exam 5: Making Connections Efficient: Multiplexing and Compression

____ division multiplexing is a good technique for transmitting multiple concurrent signals over a fiber-optic line.

The inability of a single fiber-optic line to meet users' needs is called ____________________.

Multiplexing is a technique typically performed at the network access layer of the TCP/IP protocol suite.

First-generation cellular telephone systems allocated channels using frequency ranges within the 800 to ____ megahertz (MHz) spectrum.

In WDM, the wavelength of each differently colored laser is called the ____________________.

Discrete multitone (DMT) is a multiplexing techinque commonly found in _______ systems.

In Stat TDM, the ____________________, provides information that the receiving multiplexor can use to detect transmission errors within the frame.

To allow multiple users to share a single medium, FDM assigns each user a separate ____.

____ is the technology behind the popular digital subscriber line (DSL) system.

A(n) ____________________ is an assigned set of frequencies that is used to transmit the user's signal.

The big advantage of frequency division multiplexing over synchronous TDM is the lower noise due to the use of digital signals during transmission.

Under normal circumstances, the synchronous time division multiplexor maintains a simple ____ sampling order of the input devices.

Presently, a medium can be divided in three basic ways: a division of ____, a division of time, and a division of transmission codes.

SONET was developed in the United States by ____.

____ gives each incoming source signal a turn to be transmitted, proceeding through the sources in round-robin fashion.

____________________ is a modulation technique that involves a four-bit code in which eight phase angles have a single amplitude, and four phase angles have double amplitudes.
