Section 2 - Installing The Router

• Connect an RJ-11 cable between the wall phone jack and the line-end of the splitter (see diagram below).

• Attach another RJ-11 phone cable to the router-end of the splitter and the ADSL port on the rear panel of the router.

• The phone-end of the splitter will be connected to the telephone using a third RJ-11 phone cable.

Installing the Router

Connect the ADSL and Telephone Lines

NOTE: See connections on the installation diagram.

Connect the PC to the Router

• To use the Ethernet connection, connect the Ethernet cable from the computer directly to the router. Connect one end of the Ethernet cable to the port labeled LAN on the back of the router and attach the other end to the Ethernet port of your computer.

• If your LAN has more than one computer, you can attach one end of an Ethernet cable to a hub or a switch and the other to the Ethernet port (labeled LAN) on the router. Note that either a crossover or straight-through Ethernet cable can be used. The router automatically recognizes the type of connection that is required.

UBR service is suitable for applications that can tolerate variable delays and some cell losses. Applications suitable for UBR service include text/ data/image transfer, messaging, distribution, and retrieval and also for remote terminal applications such as telecommuting.

UBR service is suitable for applications that can tolerate variable delays and some cell losses. The Peak Cell Rate is a determining factor in how often cells are sent in an effort to minimize lag or jitter caused by trafﬁc inconsistencies.

Used by applications that require a ﬁxed data rate that is continuously available during the connection time. It is commonly used for uncompressed audio and video information such as videoconferencing, interactive audio (telephony), audio / video distribution (e.g. television, distance learning, and pay-per-view), and audio / video retrieval (e.g. video-on-demand and audio library).
