Service Overview
"Business Ether WIDE" from NTT EAST is a next-generation broadband Ethernet service that utilizes NGN technology to deliver much higher quality, higher reliability than ordinary broadband Ethernet services.
Broadband network including inter-prefecture services, and charging options
With Business Ether WIDE, a broadband network that spans multiple prefectures in Eastern Japan can be provided with a single one-stop service that covers all steps from application to development, maintenance and invoicing. (*1)
Connecting to networks of participating carriers means a seamless network can be developed that spans the entire country. (*2)
If the customer has offices within the same zone, they can select either an "inter-prefecture trunk line" or an "intra-zone trunk line" to suit their network configuration so that the service can be used at the optimum charges. (*3)
Zones designated by NTT EAST
| Tohoku Zone | Aomori Prefecture, Akita Prefecture, Iwate Prefecture, Yamagata Prefecture, Miyagi Prefecture, Fukushima Prefecture |
|---|---|
| Kanto-Koushin'etsu Zone | Niigata Prefecture, Nagano Prefecture, Yamanashi Prefecture, Gunma Prefecture, Tochigi Prefecture, Ibaraki Prefecture, Saitama Prefecture, Tokyo Metropolis, Chiba Prefecture, Kanagawa Prefecture |
- *1:Customers may have to wait for the service to become available, or the service may not be available at all, depending on the state of equipment and other circumstances, even within the area the service is provided.
Please contact NTT EAST sales staff for more information. - *2:To use the service throughout Japan, a separate contract for a line or connection with participating carriers (such as NTT WEST) is required.
- *3:If all offices are within the same zone of the same communication group, customers can select either an "intra-zone trunk line" or an "inter-prefecture trunk line."
Each zone includes the following prefectures.
Tohoku Zone: Aomori Prefecture, Akita Prefecture, Iwate Prefecture, Yamagata Prefecture, Miyagi Prefecture, Fukushima Prefecture
Kanto-Koushin'etsu Zone: Niigata Prefecture, Nagano Prefecture, Yamanashi Prefecture, Gunma Prefecture, Tochigi Prefecture, Ibaraki Prefecture, Saitama Prefecture, Tokyo Metropolis, Chiba Prefecture, Kanagawa Prefecture- An "intra-zone trunk line" and "inter-prefecture trunk line "cannot be used together with the same communication group.
To use an "intra-zone trunk line," no connection can be made with the networks of participating carriers. - To change between "intra-zone trunk line" ? "inter-prefecture trunk line," installation work is required that will result in interruptions to communications. Selecting "inter-prefecture trunk line" is recommended if there are plans to add offices in the future that extend beyond zones.
- An "intra-zone trunk line" and "inter-prefecture trunk line "cannot be used together with the same communication group.
- *4:MA (Message Area) refers to an area designated by NTT EAST in which calls can be made at the local call rate.
Please contact NTT EAST sales staff about the MA of your office.
High reliability with constant monitoring and malfunction notification for each line
Business Ether WIDE utilizes Ethernet OAM technology (for checking communication with monitoring frames) to constantly monitor each line. In the event that there is a malfunction, the maintenance center quickly sends a notification of the malfunction, resulting in reliability that is so much higher than ordinary Ethernet services.
- *Constant monitoring by Ethernet OAM uses a portion of the subscribed bandwidth.
- *Specify an email address that can be used even if there is a malfunction in the Business Ether WIDE line for sending malfunction notifications.
Comprehensive security and a high level of reliability
Business Ether WIDE is a closed network equivalent to a dedicated service. Virtual LAN technologies are employed to provide ample security for each customer, so there is no need to worry about unauthorized access.
The network between trunk lines is designed with redundancy as standard, and additional redundancy options are also available between access sections (Dual Access). In the event of malfunctions, the network will automatically switch to the backup line. This allows business networks that require extremely high levels of reliability to be developed.
In order to reduce costs for the customer when implementing Dual Access, the "Dual Access Selector Type" is available in a single optical network unit (ONU) to provide redundancy between access sections in addition to "Dual Access Normal Type," which requires two optical network units (ONU).
SLA (Service Level Agreement)
NTT EAST's SLA is one of the highest levels available in the industry. A high level SLA is available in three areas: "failure recovery time," "delay time" and "uptime."
A new failure recovery time SLA of less than 10 minutes has been set for the Dual Access category with Business Ether WIDE. This delivers a much higher service quality than ordinary Business Ether.
- Failure Recovery Time SLA (less than 10 minutes/less than 30 minutes)
- Delay Time SLA
- Uptime SLA
Developing an efficient network by interworking with FLET'S VPN WIDE
An interworking connection with FLET'S VPN WIDE means a well-modulated network with an ideal balance between reliability and cost to suit the number of offices and application can be developed. (*5)
- *5:To use FLET'S VPN WIDE, a separate contract is required.
Seeherefor more information on FLET'S VPN WIDE service details.
Extensive Range of Optional Services
An even more effective and efficient communication solution can be developed as Business Ether WIDE can be used with any combination of a wide range of optional services.
| Network equipment can be rented | Rental CPE |
|---|---|
| Improved network stability and reliability | LAN / WAN Monitor |
| Other Optional Services | Subgroup Setting Function |
| QoS Control Function | |
Filtering Setting Function * In Japanese only |

| Reporting Service* In Japanese only |
Dual Access
Ethernet with a greater level of reliability
As a means of safeguarding against intra-access zone failure, the line redundancy service has enabled a significant reduction to the cost of 2 single access lines, which in the past was necessary.
It is not only for those who need reliability and stability across backbone and core banking networks, but together with the growing requirements of BCPs(Business Continuity Planning), it acts as a precautionary measure for those who want a more reliable Ethernet service, or for those who are concerned about the reliability of their current Ethernet service.
- *1:UNI=User-Network Interface
- *Dual access requires 1 subscription for 2 lines.
- *Back-up lines can only be used during times of line failure.
