communications: A modem connector that physically links to a telephone handset,.unlike the more common direct-connect modems that plug into the phone line. Useful if you're traveling or at a location (such as an unfamiliar country or office) with nonstandard phone service. While early versions were less reliable and slower than today's modems, within the last few years a wide variety of acoustic couplers have become available.
This is an acoustic modem that transfers data over phone lines by tones and sounds instead of electronically. Old-fashion handsets fit into a the modem to transmit information.
Equipment used in the conversion of electrical signals into audio signals in order to transmit data over a PSTN.
A device into which a telephone handset slots to produce a modem to be used over standard telephone lines. Return
A device that converts electric signals into audio signals, enabling data to be transmitted over the public telephone network via a conventional telephone handset.
Device that allows a telephone handset to be used for access to the switched telephone network for data transmission. Digital signals are modulated as sound waves, and data rates are typically limited to about 300 bps, some up to 1.2K bps.
A type of modem which generates audible tones so that computer based data can be transferred into a transmission medium using a standard telephone hand-set.
The portion of a modem that physically holds a telephone handset in two rubber cups. The cups house a small microphone and speaker that "talk" and "listen" to the telephone handset. ... more
a device for connecting a computer modem to the handset of a conventional telephone without any wires
a device which plugs into the serial interface at one end and a telephone at the other
a modem that uses the handset on a telephone to connect with the phone lines
A type of communications equipment that converts data to sound nd vice versa so that a telephone handset may be used to transmit data.
Device for establishing a connection with sound signals rather than electricity. Interface for coupling electrical signals by acoustical means, usually into and out of a telephone instrument. A terminal device used to link data terminals and radio sets with the telephone network.
A type of modem which converts digital signals into sound for transmission through telephone lines, and performs the reverse operation when receiving such signals. Acoustic couplers generally have cups for the telephone handset.
An interface device for coupling electrical signals by acoustical means--usually into and out of a telephone instrument. ( 188) terminal device used to link data terminals and radio sets with the telephone network. Note: The link is achieved through acoustic (sound) signals rather than through direct electrical connection.
This is a special cradle in which you place the handset of a phone. This is connected to a modem, and the modem accesses the phone line through this coupler. Modern modems connect directly to the phone line.
A special type of modem that permits a standard telephone headset to attached to a terminal, allowing transmission of data.
A form of modem that does not connect directly to the phone line, but generates audible tones that are then transmitted through the telephone handset
A device which converts data (in digital form) into sequence of tones (analogue signals), so enabling transmission over standard telephone lines. An acoustic coupler is connected by inserting a standard telephone hand set into two rubber cups that are attached directly to the terminal from which data is being transmitted, or to a separate modem. At the receiving end the tones are converted back tot digital form by a modem.
A low speed modem which converts digital signals to and from audible analogue form for transmission via an ordinary telephone handset.
