Disconnecting Data Calls 89

Disconnecting Calls

Automatically Using

Timers

There are a number of ways by which you can c onfigure calls to be disconnected

automatically. You can set timers and disconnect thresholds from the Data Call

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 beca use of inactivity.

Once the minimum call duration is sati sfied and then no activity is detected for a

call, this timer is started. To prevent a data call from being disco nnected 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

Parameters

You can specify when you want a second B channel to be added automatically

based on the utilization of the first B channe l.

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 f irst 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 Mo dem should wait before

adding the second B channel. By default the length of time is 10 seconds.

Therefore, this default, in combination with the C onnect/Disconnect Threshold

default means that after a B channel reaches ov er 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 Mo dem should wait before

removing the second B channel. By default th e length of time is 20 seconds.

Therefore, this default, in combination with the C onnect/Disconnect Threshold

default means that if throughput falls below 60 % for 20 seconds, a B channel is

removed.
