The media converter remains in the Diagnostic state until the following condition is met: the link status for
both of the media converter’s ports is up, simultaneously.
After that condition is met, ALPT
enters the Active state. It remains in the Active state until the converter
is powered down. In the Active state, Active LPT works as shown below (the same as when regular LPT
is enabled).
See the
ALPT description
on the Transition Networks website for more information.
Automatic Link
Restoration
The media converter will automatically re-establish the link when connected to switches if the link is lost.
Distance Extension
The M/GE-ISW-SFP-01-PD media converters can segment one Ethernet and/or Fast Ethernet and one
fiber Fast Ethernet collision domain:
•
In a half-duplex Ethernet or Fast Ethernet environment, the M/GE-ISW-SFP-01-PD media
converters extend network distances by segmenting collision domains so that the 512-Bit Rule
applies separately to each collision domain.
•
In a full-duplex Ethernet or Fast Ethernet environment, the M/GE-ISW-SFP-01-PD media
converters extend network distances to the physical cable limitations imposed by the selected
twisted-pair copper fiber cables.
Rate Conversion
The M/GE-ISW-SFP-01-PD media converters allow connection of 10Mbps terminal devices on a 10Base-
T legacy Ethernet copper network to terminal devices on a 100Mbps Fast Ethernet or 1000Mbps Gigabit
Ethernet copper network and/or terminal devices on a 100Mbps Fast Ethernet or 1000Mbps Gigabit
Ethernet fiber network.
