What are concentrators, Computer Engineering

Assignment Help:

What are concentrators? Explain how it helps in connecting number of subscribers.

In rural areas, subscribers are usually dispersed. This is both unessential and expensive to give a dedicated pair for each subscriber. Three techniques are utilized to gain on the number pairs are as following:

1. Parity lines

2. Concentrators

3. Carrier Systems.

In second technique, a concentrator expander (CE) is utilized near the cluster of users and other one at the exchange end as demonstrated in figure.
