IP phones
Each IP phone subscription comes with one phone number (0AB to J number) and eight channels.
Customers add numbers and channels (see Note) optionally.

Note:  The number of channels represents the number of simultaneous connections.

figure: IP phones

* One IP phone subscription allows the use of up to 500 channels. Subscribing to an additional IP phone allows a maximum of 1,000 channels per access line.
* Calls to emergency numbers 110 (police), 119 (fire/ambulance), or 118 (coast guard) are not available. We strongly recommend that you retain at least one telephone line that allows you to call emergency numbers.

Indoor equipment

Equipment supplied by KDDI

We rent out media converters and an EGWs to our customers. Existing PBX/telephone sets may be used continuously. We offer two types of EGWs for rent: analog type (COT: 8 channels) and digital type (PRI: 23 channels). We are also planning to start offering the digital type (BRI: 8 channels) and OD trunk type for rent within fiscal 2005.
Media converter rental fees are included in the basic charge.

* Customers may also arrange for their own GW equipment supporting IP-PBX, PRI, BRI, or OD rather than using rented terminals. Please allow us to advise you on what equipment supports KDDI Hikari Direct.

A router needs to be installed.

* The IP phone and Internet segments are separate.
* The IP phone segment does not require filtering by the router since it already undergoes filtering within the network to control access from the Internet.

If you subscribe to an Internet connection in addition to the IP phone, you will need to use a router for achieving your indoor voice quality standards. Only router models recommended by KDDI may be used.
