Access concentrator; Remote access concentrator
concentrator
<communications> A device that combines the data streams from
many simultaneously active inputs into one shared channel in
such a way that the streams can be separated after
transmission. The concentrator's output bandwidth must be at
least as great as the total bandwidth of all simultaneously
active inputs. A concentrator is one kind of multiplexing
device.
For example, a concentrator may be used to connect 24 2400 bps

Concentrator
In telecommunication, the term concentrator has the following meanings:
- In data transmission, a functional unit that permits a common path to handle more data sources than there are channels currently available within the path. A concentrator usually provides communication capability between many low-speed, usually asynchronous channels and one or more high-speed, usually synchronous channels. Usually different speeds, codes, and protocols can be accommodated on the low-speed side. The low-speed channels usually operate in contention and require buffering.
- A device that connects a number of links with only one destination, the main function of this device is to make a kind of load balancing between two or more servers connected together, data distribution is done according to the server processing rate.
- A patch panel or other component in the cable plant where cable runs converge.
- ISP used concentrators to enable modem dialing; this kind of concentrator is sometimes called a modem concentrator or a remote access concentrator. The term "access concentrator" is also used to describe similar provider edge equipment used in computer networks that doesn't rely on modems anymore, e.g. FTTH.
