Table 8-2. X.21 Link Parameters

Option	Default	Description
1. Local X.21	Data Activity	Data Activity is currently the only option on this menu.
Connect Mode	Connect	Therefore, Data Activity Connect is the only option for Multiserver
		ports. For feeder-mux ports, there is another option (DTR). Data
		Activity Connect causes a connection to be made to the X.21 network
		whenever there is data activity on a channel or port that is connected
		to a class of ports (on a feeder mux) via an X.21 link.
		When you select Data Activity Connect, you will be asked to set (in
		seconds) the data-activity timeout period:
		ENTER X.21 NUMBER OF SECONDS: [5]
		Enter the desired time in seconds, from 1 to 20 (the default is 5). You
		must use whole numbers. Press <cr>. To terminate and return to the
		Command Facility Main Menu, press ^X.
		When the X.21 link is in use and the Multiserver does not detect data
		activity within the specified time, it will time out and drop the
		connection. The link will remain in readiness for a call until the next
		call request.
