Using the Telnet Viewer
The DSView 3 management software ships bundled with a built-in proprietary Telnet Viewer that 
provides features unavailable in many other Telnet programs. These features include configurable 
session properties tailored for each device, configurable user preferences for all sessions, a 
scripting function for automatic device login, a macro function and a logging function.
About the Telnet Viewer
DSView 3 software clients may use the DSView 3 management software Telnet Viewer to access 
CPS810 and 1610 appliances and their ports, CCM 850, 1650 and 4850 appliances and their ports, 
or any generic appliance that supports Telnet Viewer connections.
NOTE: Throughout this chapter, the term “appliance” or “managed appliance” will be used to indicate a 
supported CPS appliance, CCM appliance or generic appliance that supports Telnet Viewer connections.
When a session is established with a supported appliance, the Telnet client switches to SSH (Secure 
Shell) mode and opens an SSH shell to/through the appliance. The SSH shell can use any of the 
Telnet client’s terminal emulations. See Security Property on page 290.
The Telnet Viewer uses the credentials provided by the DSView 3 software to establish a session 
and will automatically accept the appliance server key. The username and password provided by 
the users when they log in are authenticated by the authentication service configured in the 
DSView 3 software.
Requirements
The Telnet Viewer is actually an applet that runs within the Java 1.5.0_02 plug-in (JRE). The 
Telnet Viewer may also work with other Java versions. The DSView 3 software client 
automatically downloads and installs the JRE (Java Runtime Environment) the first time the Video 
Viewer or the Telnet Viewer is launched. SeJava Installation on page 19 for information about 
user interaction with the JRE installer.
Telnet Viewer Window Features
A new Telnet Viewer window will open for each new Telnet session established by a user. The 
Telnet Viewer window contains menus, a toolbar and a window that provides virtual terminal 
emulation.
