As shown in the figure above, the arrowhead of a dotted line indicates the
direction of an established TCP connection, from the initiator to the receiver.
The purple dotted line represents TTY/Telnet terminal access. The bank outlet is
connected to the FEP of the branch through Router A, which is capable of terminal
access, over an IP network. Banking services run on the FEP, and the information
entered by an employee at the bank outlet is sent to the FEP through Router A.
The FEP then sends the corresponding service display to the service terminal
through Router A, thereby implementing data exchange between the outlet and
the branch.
The orange dotted line represents RTC terminal access. Router B acts as an RTC
client and Router A the RTC server. Router B initiates monitoring requests and
Router A, upon receiving a monitoring request, sends the data from the monitored
terminal to the monitoring device through Router B, so as to implement terminal
monitoring.
The following table lists the features of terminal access. "All" in this table means
that all the terminal access types, including TTY, Telnet, and RTC (RTC client or RTC
server), support the feature.
