Start Connection is used to determine under which conditions is a 
line established. To use this function, the line must not be 
designated as answer only. After a physical connection is made, 
data is transferred. 
The line is established when the unit is turned on. Upon Power Up 
is recommended for leased lines only 
The line is established when any frame that is directed to the link 
arrives 
The line is established only when specific types of frames directed 
to the link arrive. To determine which frames establish a line, filters 
are used to specify the type of frame. 
Any number of filters can be used. Filters work as a Boolean "OR"; 
by specifying a filter for frame type A and filter for frame type B, 
you establish a line for Frame type A or Frame type B. 
Choosing this option automatically opens the Advanced Filter 
menu, with Connect Operation selected 
The line is permanently cutoff. In this case, you manually decide 
when to activate a line.

The line is terminated after a specified time passes without a frame 
passing through the line. You specify the time in which a frame 
must pass. The default is 60 seconds 
The line is terminated after a fixed period of time regardless of the 
traffic. The default is 60 seconds 
The line is terminated if traffic of a specific type of frame falls below 
a certain rate over a period of time. You determine the number of 
frames and the time period in which they must pass. Using filters, 
you specify which type of frames are counted. If frames other than 
those specified pass through, they are not counted. 
Choosing this option automatically opens the Advanced Filter menu
