See the Command Reference for more detailed command descriptions and instructions.WAN ports uses is explained in detail in Chapter 7, Router Installation and Configuration Manual/Configuring a Synchronous Serial WAN Interface and in Chapter 31 Router Installation and Configuration Manual/Basic Networking.The file is explained in detail in Chapter 5, Router Installation and Configuration Manual/Configuring a LAN Interface, and in Chapter 31, Router Installation and Configuration Manual/Basic Networking.

voice interface must be shutdown before updating configuration-83voice interface must be shutdown before updating configuration-90

The first ISDN BRI port will be bri0, then bri1 and so forth.

Using the router's default configuration below, we have modified the interface name to reflect the use of ISDN BRI interface: You can assign description to all WAN ports.

Once you have determined the type of synchronous connection to use between your remote locations, the synchronous port on each end of the connection must be configured. In general, Image Stream follows this ordering convention: The default configuration uses "Serial0" as the device name.

If your WAN interface is not an ISDN BRI interface, please see the appropriate chapter in this manual. In this chapter, we will discuss the configuration of ISDN BRI interfaces. To assign the proper device name to a port, enter this command in the file in the Serial interface configuration section: The "XX" above denotes the number of the BRI interface.

The syntax of this command is: Set the IP address to the address to be used by the serial interface of the router on your network.

If you have divided your network into subnets, enter the subnet mask that identifies how your network addresses are divided between the network portion and the host portion.Before configuring the WAN interface, you must make the appropriate cabling connection for your needs.Refer to the hardware installation guide for your Image Stream product for information on making the WAN connection.The default setting is for the North American National ISDN, or NI-1, switch, but the BRI card can also support German 1tr6 and European EDSS-1/NET3 (Euro-ISDN) switches.For use in most other environments, a none option that does not set any specific ISDN switch variables is supported.It is not necessary to enter "no" and a command to negate the command.
