Appendix C: Troubleshooting guide

After completing installation and activation of the
MetroCell, if the signal strength you receive on your
handset has not improved or you are unable to make calls
or use data applications, follow the steps outlined in this
appendix.
If you have multiple small cells at the same site and are
experiencing poor voice quality, slow data speeds, or dropped
calls, the cause may be interference between the cells. It
may be necessary to increase the separation between cells or
otherwise shield the cells from each other.
Preliminary steps
• Power down the MetroCell and wait 10 minutes.
• Power up the MetroCell and wait at least 15 minutes.
• Ensure that an appropriate (3G-capable) mobile device is
available.
• If the MetroCell has been configured to operate in "Closed"
mode, ensure that the device(s) being used to make test calls
is on the Approved User List (see the AT&T MetroCell User
Guide available at att.com/metrocell).
• Check that an Internet router is installed.
• Check that the Internet line is working properly.
• Ensure that access to the router and MetroCell are available.
LAN configuration requirements
Verify that the LAN Configuration Requirements in
Appendix A are met. This may require adjustment of certain
router parameters.
Debug interface
A number of LEDs and a reset button are located behind the
removable cover for debugging purposes (see Figure 2).
LEDs provide status indication for:
• Power
• System
• Phone (Device)
• Second Ethernet port
(not used in the typical installation)
• GPS
These LEDs can be used to help diagnose problems – see the
troubleshooting steps below.
