Fast VTY service switching
The characteristics of banking services require each bank branch to provide
services such as deposit and corporate services. However, a terminal at an outlet
can process only one type of service. To solve this problem, the terminal access
feature of the router implements the VTY switching function, enabling a terminal
to process multiple services at the same time and to switch between the services
dynamically.
In terminal access, each terminal is divided into eight virtual type terminals (VTYs)
logically, each of which can be configured to correspond to a service (also known
as an application). An operator of a terminal can press the VTY switching menu
hotkey to bring up the VTY switching menu and select a VTY to switch between
different services dynamically. This allows more flexible use of terminal access. In
addition, the VTY switching feature provides the screen saving function. When an
operator switches from service 1 to service 2, the operating interface of service 1 is
automatically saved. When the operator switches from service 2 back to service 1,
the original operating interface is automatically restored. If the original operating
interface is lost due to a fault, the operator can use the terminal redrawing
function to recover it.
VTY redrawing
You can set the VTY redrawing hotkey on the router. When a terminal does not
display the normal terminal interface for some reasons (for example, when illegible
characters appear after the terminal is turned off and then turned on), pressing
the terminal redrawing hotkey can restore the normal terminal interface.
Idle connection timeout
If the idle connection timeout function is enabled and no data is transmitted
between the initiator and receiver within the idle connection timeout period, the
initiator and receiver are disconnected from each other automatically.
Terminal number fixing
As shown in Figure
connected to the terminal enables the terminals to access the FEPs. The terminals
are connected to the router through asynchronous serial interfaces. The router
numbers all the terminals. On the other side, the router connects to multiple FEPs
over the network. Each FEP runs multiple applications. Terminal access universally
numbers all the applications, regardless of whether these applications are running
on the same FEP or on multiple FEPs. With the numbering of the terminals and the
applications and the special processing through the router, the mappings between
the terminals and the banking services are established to implement fixed terminal
numbering.
