Disconnecting Data Calls

89

Disconnecting Calls There are a number of ways by which you can configure calls to be disconnected Automatically Using automatically. You can set timers and disconnect thresholds from the Data Call

Timers Parameters window. Specifically, the parameters you can set are as follows.

Minimum Call Duration

Enter the minimum length of a call that is measured before the ISDN LAN Modem detects inactivity on the connection and then starts an inactivity timer. The default is 2 minutes.

Idle Timeout

In the field Disconnect a data call after how long of an inactivity period?, enter the number of seconds after which a call should be disconnected because of inactivity. Once the minimum call duration is satisfied and then no activity is detected for a call, this timer is started. To prevent a data call from being disconnected because of inactivity, enter 0. The default for an automatic call is 30 seconds. The default for a manual call is 15 minutes.

Bandwidth on Demand You can specify when you want a second B channel to be added automatically Parameters based on the utilization of the first B channel.

Connect/Disconnect threshold for the second B channel

If you specified that you want to use the second B channel only when needed, indicate the percentage of bandwidth on the first B channel which must be reached before the second B channel is allocated. By default the threshold is 60%.

Connect Delay

This field defines the length of time the ISDN LAN Modem should wait before adding the second B channel. By default the length of time is 10 seconds. Therefore, this default, in combination with the Connect/Disconnect Threshold default means that after a B channel reaches over 60% throughput for

10 seconds, a second B channel is added, if not already in use.

Disconnect Delay

This field defines the length of time the ISDN LAN Modem should wait before removing the second B channel. By default the length of time is 20 seconds. Therefore, this default, in combination with the Connect/Disconnect Threshold default means that if throughput falls below 60% for 20 seconds, a B channel is removed.
