Chapter 6. Troubleshooting

Power/Line LED, B1, and B2 LEDs Flash Green

This indicates a configuration problem. Verify the following in- formation is correct:

•Switch Type

•Service Profile Identifiers (SPIDs) (used in North America only)

•ISDN Phone Numbers

This information can be viewed by choosing the Status Register button under the Diagnostics tab of the ADTRAN Express Con- figuration Wizard window or the Configuration Screen in the VT 100 menu system. The Link Status should indicate Link Up if all configuration information is correct and the unit is properly con- nected. If the link status is good and calls still can not be placed, review the section for Dial-Up Connection Problems on page 55.

Auto-Detect can be used under the Wizard button in the ADT- RAN Express Configuration software (or by using the Auto-De- tect SPIDs/Switch option in the Configuration screen of the VT 100 menus) to automatically detect the SPIDs and the Switch Type. This only applies to North American switches.

1.Look for the following with the COM port setup:

•IRQ conflicts.

•Wrong DTE speed.

•Use Microsoft diagnostics (msd.exe) to verify the COM port has 16550 UART (for speeds of 115.2 kbps and below) or a 16650 UART (for speeds up to 230.4 kbps).

•Proper COM driver is installed (not provided) to support DTE speeds above 19.2 kbps.

2.Verify the correct protocol is selected:

•PPP or V.120 generally for Internet applications

•V.120 or Async BONDING for work-at-home

Power/Line LED, B1, and B2 LEDs flash green sequentially. After a soft- ware upgrade, if the Power/Line, B1 and B2 LEDs flash green in se- quence, a problem occurred. Restart the download using the instructions in on page 49, If the download fails a second time, contact ADTRAN technical support.
