Bandwidth Control - IMC Networks IE-MiniFiberLinX-II Operation Manual

Auto-Negotiation, Duplex Mode and Speed
The twisted pair port on the IE-MiniFiberLinX-II 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-MiniFiberLinX-II 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-MiniFiberLinX-II 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-MiniFiberLinX-II 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 for configuration information.
FX/TX LinkLoss and FiberAlert
The IE-MiniFiberLinX-II 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.
