Overview
The Radiance SONET single interface line card provides seamless
integration between fiber optic multimode and singlemode segments in OC-3/
STM-1 or OC-12/STM-4 networks. Use the card’s singlemode connector to
extend your network reach up to 40 km.
The Radiance line card is manageable through console commands, Metrobility’s
GUI-based NetBeacon® or WebBeacon software, or any SNMP application. This
ability provides software control over the card’s configuration and notification
of a failure to a management station.
The Radiance SONET single interface line card offers the following key
features:
•Two Link Loss Return (LLR) switches and Link Loss Carry
Forward (LLCF) to aid in troubleshooting remote network
connections.
•Full-duplex support.
•OC-3/STM-1 (155Mbps) and OC-12/STM-4 (622Mbps) support.
•A link LED on each port to indicate that the port is receiving a
signal.
•Reliable data transmission over multimode cables up to 2 km and
singlemode cables up to 40 km.

Installation Guide
Follow the simple steps outlined in this section to install and start using
your Radiance SONET single interface line card.
NOTE: Electrostatic discharge precautions should be taken when handling any
line card. Proper grounding is recommended (i.e., wear a wrist strap).
Unpack the Line Card
Your order has been provided with the safest possible packaging, but
1
shipping damage does occasionally occur. Inspect your line card
carefully. If you discover any shipping damage, notify your carrier and
follow their instructions for damage and claims. Save the original
shipping carton in case return or storage of the unit is necessary.
Set the DIP Switches*
A set of six DIP switches is located on the back of the line card. (See
2
illustration.) Two of these switches are used to enable/disable Link
Loss Return (LLR) and are clearly marked LLR1 and LLR2 on the
printed circuit board.
The remaining switches, including the one labeled LLCF, are nonfunctional. Pushing these switches up and down has no effect. Link Loss
Carry Forward (LLCF) is a feature that is always enabled.
When setting DIP switches, the UP position is when the lever of the
DIP switch is pushed away from the circuit board. The DOWN position
is when the lever is pushed toward the circuit board.
The default switch settings are LLR1 disabled (DOWN) and LLR2
disabled (DOWN).
*DIP switches also can be controlled by console commands or with Metrobility’s NetBeacon or WebBeacon management
software. Refer to the
