VERIFICATION OVER A WAN CONNECTION

1. Determine if a remote IP Host (Host B) can access the system. On the remote IP host type:

ping 100.0.0.1

2. If a message similar to the following is displayed, the IP host mode feature over the specified

WAN connection is operational.

100.0.0.1 is alive

3. If this message is NOT displayed, then IP Host mode feature over the WAN connection is not

operational. Try the following:

a. Verify that the WAN connection is up. Use the

command to check for the connection.

If the connection is up, then continue with the next step.

b. If the connection is NOT up, refer to Remote Device Connectivity.

c. Follow the steps described in the section IP Host Mode Operation Over the LAN Connection.

ALTERNATE ACCESSES

DEDICATED CONNECTIONS

To verify a dedicated connection to the CyberSWITCH, the WAN lines that are connected to the

system must be available for use, and the routing option must be properly initialized.

1. View the system messages by entering the following console command:

2. Look for the following system message among the displayed messages:

Dedicated connection to device <device name> up: Slot=<slot#>,

Port=<port #>

If the above message is displayed, the dedicated connection is functioning.

3. If you see either of the following messages, you may have a problem:

Layer 1 sync not seen - Slot=<slot #> Port=<port #>

Ces=<communication endpoint suffix>

Dedicated connection down: Slot=<slot#>, Port=<port #>

Try the following:

a. With the Layer 1 sync not seen message, a physical problem has been detected on

the indicated line. Check for a proper connection to the CyberSWITCH and to the NT1 or

CIU. If the NT1 or CIU appears to be functioning properly, call your carrier service and

report the problem.

b. With the Dedicated connection down message, a remote device could not be

validated for some reason. Check the configuration for the device that will be using the

dedicated connection.

Refer to Remote Device Connectivity. Because all remote devices that use dedicated connections

are PPP devices, follow the described set-up procedure, then skip to the step specific for PPP

devices.
