58 CHAPTER 5: CONFIGURING THE ROUTER 4 Select the connection type from the Connect Type drop-down menu. ■ Always Connected means the Internet connection to your ISP is always on. ■ Auto - Triggered by Traffic means your Router will automatically connect to your ISP every time a PC needs to access the Internet. ■ Manual - Start in Disconnected means that after re-booting the Router, the Internet connection will need to be re-established manually by the user. ■ Manual - Start in Connected means that after re-booting the Router, it will automatically establish connection to your ISP. ■ Manual - Start in Last State means that after re-booting the Router, the Internet connection will stay in the previous condition before the reboot. 5 If you want your Router to automatically disconnect from the Internet after a period of inactivity, specify a time in the Idle Time (Minutes) field. (Enter a value of 0 to disable this timeout). 6 Enter the MTU value supplied by your ISP. If you do not know this, leave it at the default value. 7 The Router supports the IP Control Protocol (IPCP) Subnet Mask Support feature, check the IPCP subnet checkbox to enable it. 8 To use the IPCP Subnet Mask Support for the DHCP clients, check the IPCP Subnet Populate DHCP Server checkbox. 9 Enter the VPI and VCI parameters provided to you by your ISP in the VPI and VCI fields. You can click Auto Search to automatically find out this information. 10 Select the encapsulation type (LLC or VC MUX) in the Encapsulation Type field. This information is provided to you by your ISP. 11 Select the type of Quality of Service (CBR, UBR or VBR) in the QoS field. ■ CBR (constant bit rate): the CBR service class is intended for real-time applications, for example, those requiring tightly constrained delay and delay variation, such as voice and video applications. The consistent availability of a fixed quantity of bandwidth is considered appropriate for CBR service. ■ VBR (variable bit rate): QoS class defined by the ATM Forum for ATM networks. VBR is subdivided into a real time (RT) class and non-real time (NRT) class. VBR (RT) is used for connections in which there is a fixed timing relationship between samples. VBR (NRT) is
