METRObility Optical Systems R231-51, R231-61, R231-14, R231-47, R231-59 Radiance Access Line Cards

The Radiance access line card provides the following key features:

•Remote management using Metrobility’s unique Radiance technology which enables communication with an unmanaged remote device.

•Complete Remote Monitoring (RMON) Group 1 Ethernet Statistics support.

•Remote link testing capability that does not affect the customer’s available bandwidth.

•User-selectable maximum burst size and bandwidth allocation.

•Individual port enable/disable.

•Far End Fault functionality to detect a loss of the remote card’s fiber port receiver.

•Duplex auto-negotiation on the copper port.

•Half and full duplex support on the copper port.

•Write protect to enable or disable a remote line card from controlling a locally managed card.

•Link Loss Carry Forward (LLCF) and Link Loss Return (LLR) functionality to aid in troubleshooting.

•Push-button MDI-II/MDI-X switch on the front panel to eliminate the need for crossover cables on the copper port.

•Fused power on each line card to protect the rest of the cards in the chassis from a short circuit. The power (PWR) LED on an affected card is not lit if its fuse is blown.

•Hot swap circuitry.

•Auto-polarity on the copper port.

•Compliance with applicable sections of IEEE 802.3.

•Data frame size transparency.
