Reference Guide for the Model RT328 and Model RH348 ISDN Routers

Troubleshooting 10-5

Testing the Path from Your PC to a Remote Device

After verifying that the LAN path works correctly, test the path from your PC to a remote device.

From the Windows run menu, type PING -n 10 followed by the IP address of the remote device

you are calling.

If the path is functioning correctly, the B1 or B2 LED on the router should turn on, indicating that

a call is being placed. If the B1 or B2 LEDs do not turn on, follow these instructions:

• Check that your PC has the IP address of your router listed as the default gateway. If the IP

conﬁguration of your PC is assigned by DHCP, this information will not be visible in the

control panel network utility. Go to the Run… window and run winipcfg. The IP address of the

router should appear as the Default Gateway.

• Check to see that the network address of your PC (the portion of the IP address speciﬁed by

the netmask) is different from the network address of the remote device.

• Check Menu 12 and verify that at least one static route exists.

As the ISDN call is being set up, your PC should display a few timeouts followed shortly by

replies. If the path is not functioning correctly, only timeouts are displayed. This response

indicates that the router is unable to establish a PPP connection with the remote LAN. Refer to

the next section, “Troubleshooting a Remote Node or ISP Connection.”

Troubleshooting a Remote Node or ISP Connection

To troubleshoot a remote node or an ISP connection, follow these instructions:

• Check Menu 24.1 to verify the ISDN status. If the menu indicates the ISDN status as down,

then refer to “Troubleshooting the ISDN Line,” on page 10-2.

• Place a manual call to the remote node, using Menu 24.4.5. The progress of the call is

displayed on the screen. If the call does not connect, verify the following parameters in

Menu 11:

– Pri(mary) Phone #

– Sec(ondary) Phone #

– Transfer Rate
