OCN meaning in Networking ?

Answer:

What is Open Computer Network mean?

OCN (オーシーエヌ), or Open Computer Network(オープン・コンピュータ・ネットワーク:Ōpun Konpyūta nettowāku), is the largest Japanese Internet service provider, with over 7 million subscribers. It is owned by NTT Communications Corp, one of the largest telecommunication companies in the world. It offers dial-up and ISDN, DSL up to 50 Mbit/s and fiber up to 200 Mbit/s download and 100Mbit/s upload.

As a result of regulations intended to promote competition, OCN themselves offer only internet service (routing); the physical line can be offered by NTT (the parent corporation), or by another company. Speeds up to 1Gbit/s are offered in Western Japan, while in East Japan only 200Mbit/s is officially offered for residential use, even though the underlying fiber infrastructure is capable of 1Gbit/s.

OCN also offers an MVNO mobile broadband service called "OCN Mobile One", based on NTT Docomo's LTE infrastructure, but with data only SIM cards issued by OCN. Cards with and without SMS access are available. (In a tie-up with NTT Communications, one can install the "050+" application and use voice over IP so that the data only SIM cards can be used for voice as well.) Recently a voice sim option has also become available.
