【What we call ADSL】

《What is ISDN？》

The ISDN was adopted for the purpose of communicating information each other quickly.The ISDN was picked up from the connection of dial-up.😃

We can telephone,and do the internet at the same time with the ISDN because of being two kinds of circuits in a cable.💻

The ISDN has other strong point.Its speed of communication is 64kbps,so it's faster than an ordinary connection of dial-up,moreover we'll find it easy to connect with others.💮

However the ADSL has spread over among us so much that few people haven't used the ISDN recently individually,I'm sure.😃

Contrary to it,when using the ISDN,there is service in which we can exchange information with only no more than a single cable.We can exchange information of no less than 23 times,though it's for business use.🍻
