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.
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.
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 & User’s
Guide or WebBeacon Management Software Installation & User’s Guide for software management information.

6 Installation Guide
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.

Install the Line Card
The Radiance SONET single interface line card offers the ease of plug-
and-play installation and is hot-swappable. All cards must be firmly
secured to the chassis before network connections are made. Follow the
simple steps outlined below to install your line card.
• 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.

8 Installation Guide
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.
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.

User Guide
This section contains more information regarding the operating features of
the Radiance SONET single interface line card.
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.

10 User Guide
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.
*Units are shipped with the LLR function disabled (DOWN).
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.

Radiance SONET Single Interface Line Cards 11
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.
If a connection breaks, the line cards carriy that link loss forward to the switch/
hub which generates a trap to the management station. The network administra-
tor can then determine the source of the problem.
