Fast 
selection
Increases the amount of Call User Data that you can include in the Call Request

Fast selection is designed for short-duration, low-volume, transaction-oriented 
applications.
• ‘No’: Turns off Fast Selection.
• ‘Without Restriction’: Host replies with a Call Accept packet that can contain up 
to 128 bytes of data. The connection is established and data transfer can occur.
• ‘With Restriction’: Host replies with a Call Clear packet that can contain up to
128 bytes of data. The connection is terminated.
Closed user 
group

corresponds to the CUG specification in your network subscription.
• ‘None’: Does not subscribe to any CUG.
• ‘Standard’: Subscribes to a CUG. Enter the CUG number in the Group Number 
box.
• ‘Outgoing Access’: Can receive calls only from members of the CUG, but can
make calls to any DTE.
• ‘Bilateral’: Can receive calls from or make calls to only a specific DTE.
Group

number from your system administrator or network subscription.
