Specific Connection

It is possible to connect to more than one remote site through the ADSL modem, for example, your ISP and your corporate network. In this case, the modem's ATM channels are allocated to each site. For example, four ATM channels could be provisioned to the ISP and four channels to the corporate network. The best practice is to specify the site you want to connect to. Otherwise, the modem selects the first available connection, which could be either the corporate site or the ISP.

Check with your ISP and your corporate network administrator to verify which ATM virtual channels are cross-connected to each site. In the example shown in figure 28, channels 0-3 are cross-connected to an ISP and 4-7 to a corporate network.
