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  
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.  
1
Set the DIP Switches*  
A set of six DIP switches is located on the back of the line card. (See  
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.  
2
The remaining switches, including the one labeled LLCF, are nonfunc-  
tional. 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 Command Line Interface Reference Guide, NetBeacon Element Management Software Installation & Users  
Guide or WebBeacon Management Software Installation & Users Guide for software management information.

Link Loss Return Switches  
The Radiance SONET single interface line card incorporates Link Loss  
Return (LLR) functionality as an aid in troubleshooting remote  
connections. LLR is enabled independently on each port. When LLR is  
enabled on a port, loss of its receive (RX) link disables its own transmit  
(TX) link.  
LLR1 enables/disables Link Loss Return on Port 1, and LLR2 enables/  
disables the function on Port 2. To enable Link Loss Return for a port,  
set its LLR switch ON (up). Set the switch OFF (down) to disable the  
function.  
For more information, refer to Link Loss Return in the User Guide  
section of this manual.

to secure each card firmly  
to chassis before making  
network connections.  
Blank Panel  
Grasp the card by the front panel as shown.  
Insert the card into a slot on the chassis making sure that the  
top and bottom edges of the board are aligned with the top and  
bottom card guides in the chassis. Do not force the card into  
the chassis unnecessarily. It should slide in easily and evenly.  
Slide the card in until the top and bottom edges of the front  
panel are flush and even with the top and bottom edges of the  
chassis.  
To secure the line card to the chassis, turn the thumbscrew  
clockwise until it is snug. The card is now properly installed  
and ready for connection to the network.

Connect to the Network  
To connect the Radiance line card to the network, insert the fiber optic  
cables into the appropriate SC connectors. (See the figure below.) Be  
sure the card is secured to the chassis before making network connec-  
tions.  
4
When making network connections, make sure that the transmit (TX)  
optical conductor of the line card connects to the receive (RX) optical  
conductor of the connected device; and be sure that the transmit (TX)  
optical conductor of the device connects to the receive (RX) optical  
conductor of the card.  
Port 1 is the multimode (MM) interface. The OC-3/STM-1 models  
support a maximum segment length of 2 km. The OC-12/STM-4 line  
card supports a maximum segment length of 500 m.  
Port 2 is either a singlemode (SM) or singlemode long haul (LH)  
interface. The SM port supports a maximum segment length of 15 km,  
and the LH port supports a maximum segment length of 40 km.  
Once power is applied to the unit, correct connectivity can be verified  
via the link (LK) LED.

LED Indicators  
The Radiance SONET single interface line card provides three LEDs on the  
front panel for the visible verification of unit status and proper functionality.  
These LEDs can assist with troubleshooting and overall network diagnosis and  
management.  
When lit, the LEDs indicate the following status:  
PWR (power): The unit is powered ON.  
LK (Port 1): Port 1 is receiving valid input light level.  
LK (Port 2): Port 2 is receiving valid input light level.

Link Loss Return (LLR)  
Both ports on the Radiance SONET single interface line card have been de-  
signed with LLR for troubleshooting a remote connection. When LLR is  
enabled*, the port’s transmitter shuts down if its receiver fails to detect a valid  
receive link. LLR should only be enabled on one end of a cable and is typically  
enabled on either the unmanaged or remote device. LLR works with in conjunc-  
tion with Link Loss Carry Forward.  
The diagram below shows a typical network configuration with good link status  
using two SONET line cards for remote connectivity. Note that LLR is enabled  
as indicated in the diagram.

Example: If one of the optical conductors breaks (as shown in the diagram box  
below), Line Card B, with LLR2 enabled, will return a no-link condition to its  
link partner, Line Card A. Because the line cards are designed with LLCF  
functionality, the no-link condition is carried forward to the switch/hub where a  
trap is generated to the management station. The network administrator can then  
determine the source of the loss.

Link Loss Carry Forward (LLCF)  
The Radiance SONET single interface line card incorporates LLCF for trouble-  
shooting a remote connection. With LLCF, the ports do not transmit a signal  
until they receive a signal from the opposite port. For example, if a line card  
loses link on Port 2, the card will not transmit link pulses out of Port 1.  
The diagram below shows a typical network configuration with good link status  
using SONET line cards for remote connectivity.
