Changing Data Call Parameters 69Connect/Disconnect Threshold for the Second B ChannelIf you specified that you want to use the second B channel only when needed,indicate the percentage of bandwidth utilization on the first B channel which mustbe reached before the second B channel is allocated, or below which the firstB channel must fall before the second B channel is removed. By default thethreshold is 60%.Connect DelayThis field defines the length of time the ISDN LAN Modem should wait beforeadding the second B channel. The default is 10 seconds. This default, incombination with the Connect/Disconnect Threshold default,means that after a B channel reaches over 60% throughput for ten seconds, asecond B channel is added, if not in use by another call.Disconnect DelayThis field defines the length of time the ISDN LAN Modem should wait beforeremoving the second B channel. The default is 20 seconds. This default, incombination with the Connect/Disconnect Threshold default, means that ifthroughput falls below 60% for 20 seconds, a B channel is removed.Configuring the DataCall ParametersTo configure data call parameters, do the following.1 From the ISDN LAN Modem main page, click Data Call Parameters.2 Specify the minimum call duration.3 Specify the inactivity period for an automatic data call.4 Specify the inactivity period for a manual data call.5 If you specified that you want to use the second B channel only when needed,enter the percentage of bandwidth that must be reached on the first B channelbefore the second B channel is added or removed.6 If you specified that you want to use the second B channel only when needed,enter the length of time the ISDN LAN Modem should wait before adding thesecond B channel after the percentage in the Connect/Disconnect Threshold fieldis reached.7 If you specified that you want to use the second B channel only when needed,enter the length of time the ISDN LAN Modem should wait before removing thesecond B channel after it falls below the threshold defined in theConnect/Disconnect Threshold field.8 Click Submit.If you want to password protect the configuration profile of the ISDN LANModem, refer to “Locking and Unlocking the Configuration.”
