Troubleshooting

4.Monitor the status of the D channel LED

When you are connected to a live ISDN line, the D channel LED will be lit or flashing.

If the D channel LED remains off, it indicates that no ISDN signal present. It is likely that there is a poor connection to the local telephone company. Make sure that the ISDN cable is in good condition, and securely plugged-in. If the LED remains off, call your local telephone company for trouble shooting assistance. The problem may be the ISDN link cable, or the telephone company equipment.

If the D channel LED flashes, there is probably a mismatch between the settings of the ISDN line and the ISDN router configuration. Check the switch type setting, and SPIDs (Northern America). If the D channel LED does not lighted on after these verification, call your reseller for line configuration and troubleshooting assistance.

If the D channel LED remains on, it indicates a valid communication channel has been established and calls may be attempted by the user. The D channel LED should remain on all the time until there is problem on the ISDN line or signaling.

5.Monitor the status of the B channel LEDs

There are two B channel LEDs : B1 LED and B2 LED B1 indicate your ISDN channel activities.

If the B channel LED is off, it indicates that the B channel is in idle state. If the B channel LED is lighted on, the associated B channel is in use. It can be used for data connection or voice/fax/modem connection.

6.Monitor the status of the Ethernet LEDs.

There are four Ethernet LEDs, each designated for an Ethernet Port.

If an Ethernet LED is lighted on, it indicates that there is an Ethernet device connected to the associated Ethernet port transmitting valid Ethernet signal. If the Ethernet LED is off, either no Ethernet device is connected at the remote end, or there is a problem with the Ethernet UTP cable (RJ45) or with the Ethernet Network Interface Card (NIC).

An Ethernet LED will blink when there are Ethernet frames transmitted to or received from that Ethernet device. The Ethernet LED indicates the presence of Ethernet traffic but not the volume of the Ethernet traffic.

7.If your are unable to communicate with the router through console port

The ISDN router is designed to communicate with a VT100 terminal all time. If you are unable to communicate with the router, make sure the RS232 cable is a 9-pin male to female straight- through cable, and the baud rate is set to 9,600 baud per second.
