Trial Fiber-optic IP Connection Service Scheduled for Launch


NTT East and NTT West plan to launch a new high-speed fiber-optic IP connection service on a trial basis beginning December 26, 2000.


Service outline

NTT East and NTT West will commence a trial network service that connects customers to their contracted Internet service providers (ISPs) through the NTT East and NTT West regional IP network using fiber-optic subscriber lines that run directly to customer homes and buildings. The service will allow subscribers to access their ISPs at connection speeds of up to 10 Mbps.

We are now examining a transmission method of fiber-optic subscriber lines that offer connection speeds of up to 100 Mbps, introducing around the spring of 2001.

At the request of ISPs, we will also provide an access service that directly links ISPs and NTT East and NTT West central offices.


Objectives of trial service

(i) Evaluate transmission quality and communications features from the perspective of subscribers and ISPs
(ii) Gauge future demand under a variety of use scenarios
(iii) Evaluate methodologies for the installation and operation of fiber-optic subscriber lines
(iv) Evaluate a variety of transmission protocols and hardware architectures for fiber-optic subscriber lines


Scheduled trial service period

Six months, beginning December 26, 2000 (planned)


1.An outline of the trial service through the NTT East and NTT West regional IP networks
