Passive optical network - Enabling technologies
1 The given ONU only transmits optical packet when it is allocated a time
slot and it needs to transmit, and all the ONUs share the upstream channel in the time division multiplexing (TDM) mode

Time-division multiplexing - Statistical time-division multiplexing
1 Statistical time division multiplexing (STDM) is an advanced version of
TDM in which both the address of the terminal and the data itself are transmitted together for better
routing. Using STDM allows bandwidth to be split over one line.
Many college and corporate campuses use this type of TDM to
distribute bandwidth.https://store.theartofservice.com/the-time-division-multiplexing-toolkit.html

Telecom switch - Switch design
1 In other words, each voice channel is represented by a time division
multiplexing|time slot (say 1 or 2) on a physical wire pair (A or B)

GSM - GSM carrier frequencies
1 Regardless of the frequency selected by an operator, it is divided into time division
multiplexing|timeslots for individual phones. This allows eight full-rate or sixteen half-rate speech channels per radio frequency. These eight radio timeslots (or burst transmission|
burst periods) are grouped into a Time division multiple access|TDMA frame. Half-rate channels use alternate frames in the
same timeslot. The channel data rate for all is and the frame duration is

MII (videocassette format) - Recording method
1 For the video, luminance was simply frequency modulated and written to the Y track. The two chrominance signals, Pr and
Pb, were combined into one signal by chrominance time compressed multiplexing
(CTCM), which is a type of time division multiplexing. The resulting CTCM signal was frequency modulated and combined with the FM audio carriers before it was written to the C track.Service Manual, Panasonic MII (P.N. VQS0264) by Panasonic Matsushita Electric

Multiplexer - Telecommunications
1 In telecommunications and signal processing, an analog time division multiplexing|time
division multiplexer (TDM) may take several samples of separate analogue signals and combine them into one wide-band analog signal. Alternatively, a digital TDM may
combine a limited number of constant bit rate digital data streams into one data
stream of a higher data rate, by forming Frame (networking)|data frames consisting of
one timeslot per channel.

Dense WDM - Wavelength converting transponders
1 It essentially performs some relatively simple time division
multiplexing of lower rate signals into a higher rate carrier within the
system (a common example is the ability to accept 4 OC-48s and then
output a single OC-192 in the 1550nm band)

Pulse-code modulation - Nomenclature
1 In this respect, PCM bears little resemblance to these other forms of signal encoding, except that all can
be used in time division multiplexing, and the numbers of the PCM codes are represented as electrical pulses

come-first served).

BBC Four - History
1 This was due to the fact that on the Freeview digital terrestrial television|digital terrestrial platform, BBC Four
is broadcast in a statistical time division multiplexing|statistically multiplexed stream in Multiplex B that timeshares with the CBeebies channel (which is on air from 6.00
until 19.00)

combination of frequency-hopping and either CSMA/CA statistical time division multiplexing communication
(for data communication applications) or TDMA (for audio

Cell relay - How Cell Relay Works
1 Cell relay systems may also carry bitstream-based data such as
Plesiochronous Digital Hierarchy|PDH traffic, by breaking it into streams of
cells, with a lightweight synchronization and clock recovery shim. Thus cell relay systems may
potentially carry any combination of stream-based and packet-based
data. This is a form of statistical time division multiplexing.

DAB-S - Protocol stack
1 From an OSI model protocol stack viewpoint, the technologies used on DAB inhabit the
following layers: the audio codec inhabits the presentation layer. Below that is the data link
layer, in charge of statistical time division multiplexing and frame synchronization.
Finally, the physical layer contains the error-correction coding, OFDM modulation, and dealing with the over-the-air transmission
and reception of data. Some aspects of these are described below.

Time-multiplexing - TDM versus packet-mode communication
1 Bandwidth reservation distinguishes time-division multiplexing from statistical multiplexing such as
statistical time division multiplexing i.e. the time slots are recurrent in a fixed order and pre-allocated to the
channels, rather than scheduled on a packet-by-packet basis.
