Changing Data Call Parameters 67Configuring the LANParametersTo configure LAN parameters, do the following.1 From the ISDN LAN Modem main page, click the ISDN LAN Modem graphic.2 In the IP Address field, review the default and enter a different IP address ifrequired.3 In the Subnet Mask field, review the default and enter a different subnet mask ifrequired.4 In the Local Domain Name field, if desired, enter a name you would like to use foryour local domain. This field is not required. If you do not know what to enter,leave it blank.5 Check the Enable DHCP server box to enable DHCP or clear the box to disable it.WARNING: If you changed the IP address and/or the subnet mask of your ISDNLAN Modem, the ISDN LAN Modem will re-initialize itself when you submit thechanges by clicking Submit. When the re-initialization occurs, all calls areterminated, and you may have to reconfigure the IP addresses on the computerson the LAN.6 In the Enable NetBIOS filtering field, if desired, check the box to enable filtering.7 Click Submit.If you want to password protect the configuration profile of the ISDN LANModem, refer to “Locking and Unlocking the Configuration”.Changing Data CallParametersThis section describes how to change the default settings for the data callparameters. The data call parameters consist of time-out values and a thresholdsetting for bandwidth on demand.The timeout values are a useful means of using bandwidth efficiently and keepingtelephone usage and Internet access costs down. If there is no activity on a call foran amount of time you specify, the call is disconnected.The threshold parameters also provide a useful means of using bandwidthefficiently by automatically adding a second B channel only when there is enoughtraffic to justify the extra bandwidth, and by automatically removing the second Bchannel when one B channel is sufficient.
