International Private Leased Circuit (IPLC)
Realization of secure, high-qualified communications between two specified locations
As our customers' businesses become more international, the need for timely communications with their overseas operations is increasing. Corporate communications networks that can communicate information efficiently and reliably have become essential as the backbone of management strategy. The IPLC service is provided in more than 190 countries and regions.
Highly reliable communication
Circuits are not affected by congestion unlike overcrowded public networks, so communication is always reliable.
Communication media can be combined freely
As there are no restrictions on the communication media that may be used, you can combine voice, fax, teletype, data, images, etc., simultaneously. Under certain conditions, you can also connect to other electronic communication circuits or share the IPLC service with non-contracting parties, making for an economic and efficient network.
The IPLC service offers a varied menu to suit your applications and communication volume. Based on our close connections with overseas telecommunications carriers, we provide also solid support for your business from the time you place your order, through network establishment, operation, and maintenance.

KDDI reduces the administrative work involved in applying for the IPLC service by offering one-stop shopping in Japan. For example, you may apply for a circuit between Japan and the US, as well as another circuit between third countries such as the US and the UK at the same time.
To help customers use the IPLC service more economically, KDDI offers discount plans for three- and five-year regular usage contracts. We will discount 5% and 10% from the monthly IPLC Service charges in Japan for three-year and five-year contracts, respectively.
Depending on the areas where you will be using our IPLC service, we offer a 5-15% discount per month for all international circuit service charges. The larger the number of areas you are connected to, the higher the discount you receive.
Domestic/international service combination discount（*1）
If you use both our domestic and international IPLC services and have a single billing address, you can apply for and receive a discount on service charges. Discounts of 5% for domestic services and 15% or 30% for international services (depending on bandwidth) are offered.
Route diversity service
This service completely duplicates two high-bit links between different international zones in the same area. If a failure occurs in one circuit, you will still be able to communicate using the other route. A 10% discount on the monthly IPLC service charges is offered for each circuit.
Backup circuit service
For each IPLC that you sign up for, you will be able to use one backup circuit (reserve circuit) via a different route for the applicable international zone. If a failure occurs in the main circuit, you will still be able to communicate by switching to the backup circuit that was set up in advance using a different route. The backup circuit comes with a 40% discount on the regular monthly charges for the IPLC service, plus additional charges.
One-way circuit service
If you only send or receive data over the IPLC, we offer a discount of approximately 30% on the monthly IPLC service charges compared with the two-way service charges.
International zone change service
This is a service to temporarily switch the KDDI private leased circuit station for international zones in Japan to another pre-determined KDDI private leased circuit station when a failure occurs in your terminal equipment. Even if a fire or failure occurs within your premises, you will still be able to communicate using other communication centers. It is also possible to set up reserve domestic zones.
Zone multiplexing service in Japan
This service multiplexes domestic zones into one circuit when multiple international private leased circuits are used. This gives you the benefit of reduced domestic circuit costs, shorter lead time when increasing the number of circuits, and lower installation costs.
Diversity service in Japan（*2）
When the IPLC cannot be used due to a failure in the Japan zone, this service switches you to another domestic circuit KDDI has set up in advance. Charges for the reserve domestic circuit and additional charges apply.
- *1 Domestic ultra high-bandwidth digital service, ATM-dedicated service, and international voice-level and ultra high-bandwidth digital service are not included in this discount plan.
- *2 Discounts apply only if the fees stipulated in the contract are the standard fees (except in the case of the international diversity service).
