* An analog telephone adapter is a device that connects to the network and implements the electronics and firmware to operate a conventional analog telephone attached through a modular phone jack.

Another challenge for VoIP implementations is the proper handling of outgoing calls from other telephony devices such as digital video recorders, satellite television receivers, alarm systems, conventional modems and other similar devices that depend on access to a PSTN telephone line for some or all of their functionality.

If VoIP and cellular substitution becomes very popular, some ancillary equipment makers may be forced to redesign equipment, because it would no longer be possible to assume a conventional PSTN telephone line would be available in consumer's homes.

The conventional solution to efficient handling of telephone communication in businesses was the " message center.

Single-pair high-speed digital subscriber line ( SHDSL ) is a form of digital subscriber line ( DSL ), a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide.

It is a great help on agricultural production and post-harvest activities through the extension of financial services, basic telephone access, providing conventional media such as radio and TV and empower individual by providing training.

At the dawn of the technology, videotelephony also included image phones which would exchange still images between units every few seconds over conventional POTS-type telephone lines, essentially the same as slow scan TV systems.

On a conventional wired telephone, there are 4 connections, each of which may be hardwired, but more often uses a plug and socket:

The term Wideband Audio or ( also termed HD Voice or Wideband Voice ) denotes a telephone conversation using a wideband codec, which uses a greater frequency range of the audio spectrum than conventional voiceband telephone calls, resulting in a clearer sound.

The most common ATA is a box with at least one Foreign eXchange Station ( which includes a telephone jack ), used to connect a conventional telephone, and an Ethernet jack used to connect the adapter to a LAN.

Using such an ATA, it is possible to connect a conventional telephone to a remote VoIP server.

Telemarketers, prank callers, and other telephone system abusers are likely to target VoIP systems increasingly, particularly if VoIP supplants conventional telephony.

Since experience indicates that effluents from oxidation ponds do not create major problems at these BOD concentrations, the goal for the effluent quality of the accelerated treatment system was the same as from conventional oxidation ponds.

The desire to create air portable armoured vehicles that can still take on conventional MBTs has usually resulted ATGM armed light vehicles or in protected / armoured / mobile gun system style vehicles in which a lack of armour protection being in part offset by the provision of a first look / first hit / first kill capability through the mating of a powerful gun to superior targeting electronics, a concept similar in operation to that of the US tank destroyers of WWII.

To slow down, the rider applies resistance to the pedals, acting as a braking system which can be as effective as a conventional rear wheel brake, but not as effective as a front wheel brake.

The conventional explanation of such protection is parasites ( including bacteria ) modulate the sensitivity of the immune system.

A clanking replicator is an artificial self-replicating system that relies on conventional large-scale technology and automation.

The motion of the solar system, and the orientation of the plane of the are aligned with features of the microwave sky, which on conventional thinking are caused by structure at the edge of the observable universe

As the rule base is in everyday language ( the engine is untouchable ), expert system can be written much faster than a conventional program, by users or experts, bypassing professional developers and avoiding the need to explain the subject.

The expert system uses a rule base, unlike conventional programs, which means that the volume of knowledge to program is not a major concern.

The conventional SI system of units is based on seven basic dimensional quantities, namely distance, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

Fly-by-wire ( FBW ) is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface.

Touré had heralded this policy in 1967 when he wrote: ‘ thanks to their special political, physical, and social training, the people's militia will become the indisputable mainspring of our security system, of which the conventional armed forces constitute a fundamental section .’

Another innovation was the continuous dampening system first introduced by Dahlgren instead of the old method which is still used on older presses ( conventional dampening ), which are rollers covered with molleton ( cloth ) which absorbs the water.

Most MIDI synthesizers default to the conventional, Western, equal temperament tuning system of twelve pitches per octave, which makes types of music that depend on different intonation systems inaccessible.

This makes an SN system far easier to program and able to achieve higher sustained-to-peak performance than non-cache-coherent systems like conventional clusters or massively parallel computers which require applications code to be written ( or re-written ) to do explicit message-passing communication between their nodes.

The exception to this conventional approach is the way some large government agencies approach safety engineering from a more proactive and proven process perspective, known as " system safety ".

Plato and Aristotle both explored the relationship between signs and the world, and Augustine considered the nature of the sign within a conventional system.

The active steer system meant that the Eco-Link had a turning circle of just 41 feet, the same as a conventional articulated lorry.

Remarkably, in 1927 Baird also invented the world's first video recording system, " Phonovision ": by modulating the output signal of his TV camera down to the audio range, he was able to capture the signal on a 10-inch wax audio disc using conventional audio recording technology.

microwave radio relay and open-wire lines for conventional system ; combined fixed-line and mobile-cellular teledensity roughly 40 telephones per 100 persons with mobile-cellular use predominating

The notion of " totalitarianism " a " total " political power by state was formulated in 1923 by Giovanni Amendola who described Italian Fascism as a system fundamentally different from conventional dictatorships.
