In conjunction with an appropriate codec using MPEG or various manufacturers proprietary algorithms, an ISDN BRI can be used to send stereo bi-directional audio coded at 128 kbit / s with 20 Hz – 20 kHz audio bandwidth, although commonly the G. 722 algorithm is used with a single 64 kbit / s B channel to send much lower latency mono audio at the expense of audio quality.

Note that, as with multiplexers, links are almost always bi-directional and, at either end of the link, an inverse mux will be combined with its reverse ( an inverse demux ) and still be called an inverse mux.

From as early as 1969 various patents have been issued, covering such uses as uni-directional, bi-directional, and compatibility with auto-shut-off and anti-tape-eating mechanisms.

* Multifunction, bi-directional general-purpose I / O ports with configurable, built-in pull-up resistors

Three years after it opened, the TTC renovated its southwestern terminus at Kennedy Station, because the looped turnaround track, originally designed for uni-directional streetcars under the earlier plan and not needed for the bi-directional ICTS trains, was causing derailments ; it was replaced with a single terminal track and the station was thus quasi-Spanish solution, with one side for boarding and another side for alighting, though the boarding side is also used for alighting during off-peak hours.

DVB has standardised a number of return channels that work together with DVB (- S / T / C ) to create bi-directional communication.

From 2001 onwards, twin-tip bi-directional boards became more popular for most flat water riders, with directional boards still in use for surf conditions.

In the 1970s, the Tokyo Electric Power Co ran experiments which reported successful bi-directional operation with several hundred units.

The line is fully bi-directional, with three crossovers to allow trains to switch tracks in the event of a disruption.

The opposite end is either left open for bi-directional use, or terminated at the opposite sharp angle with a non-inductive resistor.

However, most diesel and electric locomotives ordered in Europe have been designed to be fully bi-directional, symmetrical and normally with two driving cabs.

The mission carried the Wake Shield Facility experiment and a SPACEHAB module into orbit, and carried out a live bi-directional audio and downlink link-up with the cosmonauts aboard the Russian space station Mir.

This decision put Vietnam into a bi-directional war lately with Cambodian and PRC.

The ATC system was augmented with cruise control and station stopping control and was also made suitable for bi-directional operation, and there is a driver vigilance device.

A reasonable number of the more progressive ISPs have recognised the potential for Whirlpool to act as a bi-directional communication channel with their customers.

However, all switching regulator topologies can be made bi-directional by replacing all diodes with independently controlled active rectification.

Upfield-bound trains that terminate at Coburg ( usually only occurs during service disruptions ) do so in platform 2 and can return to the city from platform 2 as well, as that platform is provided with bi-directional signalling.

Originally both platforms were bi-directional, however with the introduction of electronic signalling in 2008, platform 2 can only be used by Hurstbridge-bound trains.

A cable modem is a type of network bridge and modem that provides bi-directional data communication via radio frequency channels on a hybrid fibre-coaxial ( HFC ) and RFoG infrastructure.

A typical controller contains 3 bi-directional outputs ( i. e. frequency controlled three phase output ), which are controlled by a logic circuit.

For example SN74ALS245N means this is a device probably made by Texas Instruments ( SN ), it is a commercial temperature range TTL device ( 74 ), it is a member of the " advanced low-power Schottky " family ( ALS ), and it is a bi-directional eight-bit buffer ( 245 ) in a plastic through-hole DIP package ( N ).

The navigation starts at Weighton Lock, which is bi-directional, due to the tidal range of the River Humber.

The CICA-MIF is a structured guideline for the bi-directional exchange between X12 development tools, the central data store and other technology providers ' software that supports the interchange format.

By incorporating both uni-directional and bi-directional signals, effective switching yards, junctions, and other useful designs could be built.

These were bi-directional and were operated independently of each other.

The corporate headquarters includes: CEO as a key person and his support staff such as the CEO office and other CEO related functions ; the " Corporate policy making " functions: Include all corporate functions necessary to steer the firm by defining and establishing corporate policies ; the Corporate Services: Activities that combine or consolidate certain enterprise-wide needed support services, provided based on specialized knowledge, best practices, and technology to serve internal ( and sometimes external ) customers and business partners ; the Interface: Reporting line and bi-directional link between corporate headquarters and business units.

IEEE 1284 is a standard that defines bi-directional parallel communications between computers and other devices.

* Byte Mode, also known as " Bi-Directional " ( although all modes except Compatibility Mode are in fact bi-directional ), is a half-duplex mode that allows the device to transmit eight bits at a time using the same data lines that are used for the other direction.

The design was such that any traffic moving from one freeway to the other was routed through one common, bi-directional ramp.

# In New York, when the signalling system clears motion in one direction ( on bi-directional track or through an interlocking ), it will automatically drive the trip arms which apply to the other direction.

Shergold had an eye for innovation-pioneering features that would be used by other manufacturers ( bi-directional truss rod, semi through body neck joint on the Cavalier ), and others that have surprisingly been forgotten ( interchangeable control electronics on the Modulator series ).

There may be bi-directional signalling and suitable crossovers to enable trains to move on to the other track expeditiously ( see, for example, the article on the Channel Tunnel ), or there may be some kind of manual safeworking to control trains on what is now a section of single track.

Pod-to-pod communication is both omni-directional and bi-directional where each pod sends out collected data to every other pod in the network.

It allows bi-directional radio communication with a pacemaker or other electronic implants.
