Pause Control Frame
When the Pause Control Frame feature is activated (see page 2), it allows one
end of the link to signal the other to discontinue frame transmission for a set
period of time, relieving buffer congestion and improving network
performance.
NOTE: Both ends of a (full-duplex) Media Converter link must be able to send
and receive Pause Control Frames.
Link Pass-Through
When the Link Pass-Through feature is activated (see page 2), a fault on one
side of the Media Converter stops the signal and data transmission on the
other side of the Media Converter. If the Media Converter does not detect a
good link on the copper side, the Media Converter disables all transmission
(including active-idle) on the fiber side.
Far-End Fault
When the Far-End Fault feature is activated (see page 2), a fault on an
incoming fiber link causes the Media Converter to transmit a Far-End Fault
signal on the outgoing fiber link.
AutoCross™
When the AutoCross™ feature is activated (see page 3), it allows either
straight-through or crossover cables to be used when connecting to 100Base-
TX devices. AutoCross determines the characteristics of the connection and
automatically configures the unit to link up, regardless of the cable
configuration.

SNMP
See the on-line documentation that comes with Transition Networks
FocalPoint™ software for applicable commands and usage.
Use SNMP at an attached terminal or at a remote location to monitor the Media
Converter by monitoring:
•
Media Converter power
• Copper link and fiber link status
• Twisted-pair cable length
• Hardware switch settings
• Fault Condition
Also, use SNMP to enter network commands that:
•
Enable/disable Full- / Half-Duplex
•
Enable/disable Link Pass-Through (LPT)
•
Enable/disable Far-End Fault (FEF)
•
Enable/disable Pause
•
Enable/disable AutoCross™
• Power down the Media Converter
