Auto-Negotiation, Duplex Mode and Speed
The twisted pair port on the IE Managed Miniature Media Converter auto-negotiates
for speed and duplex mode, while also providing the option of selectively advertising
or forcing the speed and duplex mode. The optics port does not auto-negotiate; it
operates at 100 Mbps Full-Duplex. Use the management software to configure the
features on the twisted pair ports.
The IE Managed Miniature Media Converter ships from the factory with Auto-
Negotiation enabled on the twisted pair port. In this mode, the port automatically
negotiates for speed and duplex.
The twisted pair port on the IE Managed Miniature Media Converter can also be
manually set for 10 Mbps or 100 Mbps operation and for Half- or Full-Duplex (i.e. 10
Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex or 100 Mbps Half-
Duplex).
Selective Advertising, when used in combination with Auto-Negotiation, advertises
only the configured speed and duplex mode for the twisted pair port. If a specific
speed and/or duplex mode is desired, Selective Advertising should be used rather
than Force Mode, when connecting to devices that only auto-negotiate.
Bandwidth Control
The IE Managed Miniature Media Converter includes bi-directional bandwidth
control, which can be independently set, in 32 Kbps increments up to 100 Mbps.
Bandwidth control can only be configured through iView². The device features an
integrating algorithm with a 64 Kb buffer, allowing bursty traffic. This allows
operators to offer tiered services. See the iView² online help for configuration
information.
FX/TX LinkLoss and FiberAlert
The IE Managed Miniature Media Converter includes the troubleshooting features
FX/TX LinkLoss and FiberAlert. These features are enabled and monitored using
the Management software. When a fault occurs on the fiber segment, FX/TX
LinkLoss detects the fault and passes this information to the twisted pair segment.
This will display a loss-of-link signal on the remote twisted pair device.
