METRObility Optical Systems R231-15 ユーザーズマニュアル

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.
