A basic rate interface (BRI) is a type of primary rate interface (PRI) for the integrated services digital network (ISDN) that consists of two 64 kbit/s bearer channels and one 16 kbit/s data channel. The data channel is sometimes called the delta channel or delta link. The two bearer channels are sometimes referred to as the B channels.
The B channel is used to carry voice and data while the D channel is used for packet-oriented data and control information for the B channels. The B channels are multiplexed using time-division multiplexing (TDM) while the D channel uses synchronous data link control (SDLC).
configure a BRI line
To configure a BRI line you will need the following:
– A BRI line from your service provider
– An ISDN-compatible router with BRI WAN interface card (WIC)
Configuring your router with a BRI WAN interface card (WIC) will give you the ability to connect to an ISDN network. This will allow you to take advantage of the increased speeds and improved quality of service that ISDN provides.
The first step is to configure your router with a BRI WAN interface card (WIC). You will need to enter the following commands:
interface BRI0
ip address x.x.x.x y.y.y.y
encapsulation ppp
dialer map ip x.x.x.x name yyyyy number 699012345
where x.x.x.x is the IP address of your service provider’s BRI line and y.y.y.y is the IP address of your local network. The number 699012345 is the telephone number of your service provider’s BRI line.
The next step is to configure your computer to use the ISDN line. To do this you will need to enter the following commands:
isdn switch-type basic-5ess
isdn spid1 699012345
isdn spid2 699012346
where 699012345 is the telephone number of your service provider’s BRI line and 699012346 is the telephone number of your computer.
The final step is to connect your computer to the ISDN network. To do this you will need to enter the following commands:
dialer map ip x.x.x.x name yyyyy number 699012345
where x.x.x.x is the IP address of your service provider’s BRI line and y.y.y.y is the IP address of your local network. The number 699012345 is the telephone number of your service provider’s BRI line.
Your computer is now configured to use the ISDN network.
