Note: The uplink port link parallel cable to LAN Bridge.
WARNING
: When connecting to a wireless LAN bridge, the uplink Ethernet
cable often connects to the outdoor unit, posing danger to lightning strikes that
can seriously damage the equipment. To protect the equipment as well as
people, surge protection devices with good earth connection are strongly
recommended. Poor earth connection may also hinder the operation of the
Ethernet port, causing severe packet losses.

Operation
After successful installation, switch on power. The operation status can be monitored
with LEDs on the front panel. Do not use a loop back cable to suppress unused E1 port
alarms, because that shows the E1 is in operation, and will take up about 2 Mbps
bandwidth. If the uplink channel does not have enough bandwidth, this will affect
packets for the working E1.
Various operational parameters can be set or modified through Web manager.
It is often helpful to use an E1 tester to check the quality of the E1 channels, by
measuring the round trip bit error rate of the channel. The loop back control in Web
manager is useful for this purpose.
