To verify remote device connectivity to the CyberSWITCH, the WAN lines that are connected to
the system must be available for use, and the bridging and/or routing options must be properly
initialized. The remote devices must be operational and available to initiate ISDN WAN
connections.
the system must be available for use, and the bridging and/or routing options must be properly

connections.
The method of connection initiation is dependent upon the remote device type. Refer to the remote
device documentation to determine how to initiate an ISDN WAN connection.
device documentation to determine how to initiate an ISDN WAN connection.
To verify connectivity:
1.
1.
In a controlled manner, initiate an ISDN connection from each remote device.
2.
When each remote device connects to the system, it will appear as either a “REMOTE site” or
as the configured Device Name (if security is enabled) on the Monitor Connections screen. To
display the Monitor Connections screen, enter the following console command:

Note:
The terminal type must be the same for Telnet and the terminal emulation. Use the
administration console command to set the terminal type.
If each remote device is able to connect to the CyberSWITCH, then WAN connectivity is

Set-up:
The system software should be up and running. (At the administration console: if you are
in the Connection Monitor window, exit to the “[
System Name

•
Enable the call trace messages with the
trace on
console command.
•
Erase the current system messages using the
er
console command.
•
In a controlled manner, initiate an ISDN connection from the remote device.

•
After a connection has been initiated, view the system messages (by issuing the
dr
console command). Look for the following call request messages among the system
messages:
