R2511-HP MSR Router Series Terminal Access Configuration Guide(V5)

INPUT YOUR CHOICE:

Pressing any key to return

When the following events happen, this feature enables the terminal to display an error message, and

you can press any key to return to the menu interface:

• An invalid menu option is entered.

• The FEP providing the service you select is unreachable.

• A connection is terminated.

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 dynamically switch between the services.

In terminal access, each terminal is logically divided into eight virtual type terminals (VTYs), each of

which can be configured to correspond to a service (also known as an application). The operator can

press the VTY switching menu hotkey to bring up the VTY switching menu and select a VTY to dynamically

switch between different services. 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, 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 automatically

disconnected from each other.

Terminal number fixing

As shown in Figure 2, the terminal access program running on the router 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 terminals and banking services are established to implement fixed terminal

numbering.

Data encryption

Due to the extensive use of terminal access in banking systems, the requirements of data security become

higher and higher. The terminal access data encryption function can be used to encrypt the data

transmitted between the router and FEPs to improve data security.
