ETHERNET LINE SETUP
If the Ethernet port is not used, it can be set to Disabled, via a console session
or via iView², to effectively block all traffic on this port.
PACKET SIZE
The Ethernet transport can accommodate packets up to 1916 bytes.
AUTO NEGOTIATION
The IE-iMcV-E1-Mux/4 ships from the factory with Auto Negotiation enabled
on the Ethernet port. In this mode, the port negotiates for speed, duplex and
flow control.
FORCING THE SPEED, DUPLEX MODE AND FLOW CONTROL
The Ethernet port on the IE-iMcV-E1-Mux/4 can be selectively advertised or
manually forced for 10 Mbps or 100 Mbps operation at Half-Duplex or Full-
Duplex (i.e., 10 Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-
Duplex, etc.). Flow control can also be enabled on the Ethernet port when the
connecting equipment supports this. These features can be enabled through
iView² or the serial port.
FX LINKLOSS AND LFPT
During normal operation, link integrity pulses are transmitted by all point-to-
point Ethernet devices. When an IE-iMcV-E1-Mux/4 receives valid link pulses,
it knows that the device to which it is connected is up and active, and that the
cable coming from that device is intact. The appropriate “LNK” (link)
LED
is lit
to indicate this. However, these signals are not normally transmitted across a
normal store and forward Ethernet bridge function. A failed Ethernet line on
one end of the fiber link is not forwarded to the Ethernet port at the other end
of the optical transport. A failed optical line is also not normally forwarded to
the Ethernet port. The FX LinkLoss and LFPT functions are used to enable
these features.
