CHAPTER 8
TAXI Configuration
The TAXI network modules for the Cabletron
ATM
switches use the 4B/5B
TAXI format and are shipped preconfigured. No additional configuration is
needed for the TAXI network modules to interoperate with another Cabletron
Systems
ATM
switch or with any other 4B/5B TAXI interface.
8.1 TAXI Front Panel LEDs
There is an LED corresponding to both the transmit and receive lines of each
TAXI port. These LEDs provide some information about the state of the port
depending on their color.
8.1.1 Transmit Indicators
The LED corresponding to the transmit line of the port has the following
meaning depending on its color:
off Indicates that there are currently no cells being transmitted from
the port.
green Indicates that a cell is being transmitted on the port. The intensity
of the green light increases as the traffic on the port increases.
8.1.2 Receive Indicators
The LED corresponding to the receive line of the port has the following mean-
ing depending on its color:
off Indicates that a carrier has been detected on the line. A carrier is
detected when there is a proper optical signal on the line.
green Indicates that a cell is being received on the port. The intensity of
the green light increases as the traffic on the port increases.
red Indicates a loss of carrier.
