Figure 1. D3LX CO and D3LX RMT Modules
The D3LX CO module occupies two card slots in a local, Soneplex Loop Extender Chassis (LEC). The D3LX
RMT module occupies two card slots in a Four-Position Remote Terminal Cabinet, or Two-Position QLX Remote
BNC Chassis. A D3LX Remote Craft Access Module (D3RCAM) may also installed to provide maintenance
terminal access at the remote site. For more information on the D3RCAM, refer to LTPS-UM-8017-xx, the
Four-Position Remote Terminal Cabinet, refer to ADCP-61-151, or the Two-Position QLX Remote BNC Chassis,
refer to LTPS-UM-8029-xx.
The D3LX modules are part of a system that converts a metallic DS3 circuit at the CO site into a DS3 optical signal
that uses Wavelength Division Multiplexing (WDM) to transmit a signal across one single-mode fiber to a D3LX
RMT via a D3LX LTU at the CPE site. The D3LX RMT module converts the optical signal back into an electrical
DS3 and transmits the signal back to the D3LX CO residing in the LEC as shown in Figure 2 on page 2.
The D3LX modules perform the following functions:
•
•
•
•
•
•
Exchange status, alarm, and protection switching information.
Perform bit error rate monitoring of the optical link.
Monitor the optical input for Loss-Of-Signal (LOS) and Loss-Of-Frame (LOF).
Monitor the laser bias for degradation.
Retrieve remote module status.
Provide 1+1 Protect mode (line protection).

PROTECTION SWITCHING
The D3LX system may be configured for either protected or non-protected mode. For protected mode, two
modules are installed: working and protect. The working module carries the signal, while the protect module is in
standby. Each working module uses 1 group, physically occupying 2 slots. Each protected module occupies an
additional 2 slots; there are four slots required for each D3LX system.
In protected mode, the offline module is switched into service whenever the D3LX determines that a service fault
has occurred in the online module.

Front-Panel Description
Automatic Switching
The 1:1 (Line) Protect mode transmits identical traffic across two parallel systems. The working and protect D3LX
modules provide Automatic Protection Switching (APS) compatible with the remote D3LX module. APS is
non-revertive and bidirectional and may be forced or disabled through the front-panel pushbuttons or the SCU
software.
Service is automatically switched from the online D3LX module to the offline module when one or more of the
following events occur:
•
•
Offline module detects a failure in the online module.
Online module detects an optical failure. (LOS, LOF, or BER threshold is exceeded.)
APS is completed within 50 msec of the initiation of a switch. After the occurrence of three automatic switches
within a 24-hour period, APS is locked out. APS may be enabled again through the front panel interface or the
craft interface.
APS to the offline module can be disabled. To do this, simultaneously press the LMPTST/APS and ENABLE
pushbuttons on the online module’s front panel. APS can be restored by pressing both pushbuttons a second time.
BER Monitoring
The optical link is continuously monitored for bit errors. If the bit errors exceed a predetermined threshold, and
the D3LX is configured for protection, protection switching occurs and an alarm is indicated. The optical alarm
is indicated when the threshold exceeds 10-6 to 10-10 (default is 10-8). The optical switch threshold may be set
between 10-4 and 10-10 (default is 10-6).
Manual Switching
Service can be manually switched from the online D3LX module to the offline module by simultaneously pressing
the LMPTST/APS and ENABLE pushbuttons located on the offline module’s front panel. This disables the APS
causing the APS LED to turn yellow. The ONLINE LED of the new online module (formerly the protect module)
turns green, indicating a successful transfer of service. The ONLINE LED of the new offline module (formerly
the working module) is not lit, indicating it is in standby mode and not carrying the DS3 service.
APPLICATIONS
D3LX modules can be used in a number of solutions:
•
•
•
•
Switched Multimegabit Data Service (SMDS) Applications—D3LX modules support the transmission of
SMDS service through the network.
Private Line Interconnect Applications—D3LX modules provide private point-to-point LAN interconnect
services through the use of the D3LX.
DS3 Video Distance Learning Applications—D3LX modules provide high quality video signal transmission
that is the most cost-effective solution for DS3 video transport.
DS3 Asynchronous Transport Mode (ATM) Applications—D3LX modules provide high speed ATM
services using D3LX at a fraction of the cost of an OC-3 multiplexer.

Installing the BNC Panel
INSTALLING THE BNC PANEL
OVERVIEW
The ADC BNC Panel consists of 14 pairs of 75Ω BNC connectors that are part of a system that converts an
electrical DS3 circuit at the CO site into an optical signal that uses WDM to transmit a signal across one
single-mode fiber to a CPE site. The BNC Panel can support 7 working D3LX lines and 7 protection D3LX lines.
(Table 2 on page 8 lists each working slot location as labelled on the front panel of the chassis and its
corresponding protection slot.)
The D3LX CO (CO module) converts the optical signal at the CO site and the D3LX RMT (remote module)
converts the optical signal back into an electrical DS3 and transmits the signal back to the D3LX CO residing in
the Loop Extender Chassis (LEC).
A BNC Panel and ADC adapter cables are required when D3LX modules are installed. Prior to ordering ADC
adapter cables, measure the distance between the BNC Panel and the chassis. For more information about
INSTALLATION OF THE PANEL
Prior to installing the ADC adapter cables (BNC-3-CBL-WW), remove any existing wires from the
LINE wire-wrap row on the back of the LEC.

Mount the panel in the rack.
Secure the panel to the rack by using the provided screws.
On the front of the panel, connect the DS3 IN (transmit) and DS3 OUT (receive) coax cables as shown in
Figure 4 on page 8. Note the connector numbers on the BNC panel.
In every group of 4 slots, such as 1-1 through 1-4, the right most two slots have cables plugged into the bottom
2 wire-wrap pins (T1 and R1), and the two left most slots have cables plugged into the top 2 wire-wrap pins
(T and R). If it is a protected system or a single D3LX module, then slots 1-2 and 1-4 do not have cables.
For example, a D3LX CO module plugged into slot 1-1 of the chassis or in a 2 D3LX protected system:
•
The DS3 receive cable plugs into the bottom 2 pins T1 and R1 of slot 1-1. This is the DS3 that the D3LX
receives.
•
The DS3 transmit cable is plugged into the top 2 pins T and R of slot 1-3. This is the DS3 that the D3LX
transmits.
In another example, for a D3LX CO module plugged into slot 1-3 of the chassis in an unprotected system:
•
The DS3 receive cable plugs into the bottom 2 pins T1 and R1 of slot 1-2. This is the DS3 that the D3LX
receives.
•
The DS3 transmit cable plugs into the top 2 pins T and R of slot 1-4. This is the DS3 that the D3LX
transmits.

5
From the rear of the panel, connect the coax end of an ADC adapter cable to the DS3 IN (receive) connector.
The connector number must match the connector number on the front of the panel.
Connect the wire-wrap conversion block end of the same ADC adapter cable to the T and R EQUIP wire-wrap
posts on the back of the LEC as shown in Figure 4 on page 8. The top of the conversion block mates with the
T and R LINE wire-wrap posts to prevent improper connection.

INSTALLING A D3LX CO MODULE IN AN LEC
Avoid exposure to invisible laser radiation.
•
Do not look into the ends of any optical fiber or directly into the module fiber connectors as
exposure to invisible laser radiation may result.
•
•
Use a meter to verify active fibers.
Do not insert module edge connectors into the chassis connectors before connecting the
optical fiber to the module. Verify that LED indicators are not lit, and the module is not
engaged with the chassis connectors before proceeding.
When using D3LX CO modules in a group, never install other Soneplex modules in any of the
unused slots in the same group.
Remove any existing wire wraps from the LEC backplane prior to installing any ADC adapter
cables (BNC-3-CBL-WW) for the groups that are being used for D3LX modules.
Use the following procedure to install D3LX CO modules in LECs:
1
Select the fiber-optic patch cord with the appropriate length (the measured distance from the Fiber
Distribution Frame or equivalent distribution device) and the appropriate type optical connector (SC or FC
type).
2
Route the fiber patch cord through the top of the chassis, along the heat baffle/fiber management panel. Lower
the cord through the FiberGuide vertical duct to the location reserved for the D3LX CO module as shown in
Figure 5 on page 10. The protective cover must remain on the fiber connector to prevent dust and damage to
the connection. The fiber should be tagged to identify the circuit.
3
Open the front panel of the LEC into which the D3LX CO will be installed.

LTPS-UM-8013-03
15 Store the remaining slack fiber on the left side of the fiber management enclosure within the remote cabinet,
leaving 5 to 6 inches of slack fiber above the upper card guide to provide a service loop.
PROVISIONING
In D3LX systems, provisioning occurs automatically if a remote module is installed. In the event that a remote
module is not installed or properly functioning, refer to the manual provisioning process below.
MANUAL
Manual provisioning of the D3LX system may be performed locally through the SCU (version 3.7 or later) or
remotely through the D3RCAM. Craft interface software provides a user-friendly menu driven program to option
the modules in the system and maintain a provisioning database at the central office. In the chassis with the SCU,
provisioning instructions pass to resident modules through communication channels embedded in the backplane
of the chassis.
Perform manual provisioning through the craft interface of the D3LX module after installation or when changes
occur in the network system configuration. For complete information about manual provisioning, refer to the
Soneplex Loop Extender System Operation and Maintenance Manual (Version S1.0), document ADCP-61-494
and Soneplex Shelf Controller User Manual (V3.7).
AUTOMATIC
Automatic provisioning occurs in a previously provisioned system when replacing the D3LX module or when
power to the module is lost and then restored. In systems with D3LXs at the CO, the SCU provides provisioning
data to the module (slot) that powers up, based on the database established when the system was previously
provisioned.
When an SCU is replaced at the CO, the new SCU module requests provisioning data from the
D3LX CO modules in the local chassis and from the remote modules optically connected to
them. Additionally, the SCU retains its provisioning database up to 24 hours after power is lost.
The following items are configured during provisioning:
•
•
•
•
•
Protect or Non-Protect operation

OTHER PROVISIONING CONSIDERATIONS
Alarm Setting During Provisioning
The D3LX generates alarms on conditions occurring in the D3LX CO modules DS3 facility. The severity of the
alarm conditions as Critical, Major, Minor, or Event is selected while provisioning. The alarms are handed off to
an Alarm Processing Unit (APU) which acts as an interface between the D3LX modules and the customer alarm
D3 Remote Craft Access Module (D3RCAM) Option
The D3RCAM is a plug-in module for the D3LX system which provides a craft interface at the remote site.
Additionally, the D3RCAM works in conjunction with the APU and the D3LX modules to display alarm
information for the remote chassis or terminal.
SETTING UP SYSTEM OPTIONS
To configure D3LX system options, you must connect a maintenance terminal to an available craft port. You may
select either the SCU or Ports 2 or 3 (local) or the D3RCAM (remote) craft port.
•
•
If you are using the SCU, refer to “Connecting a Maintenance Terminal to the SCU Craft Port” on page 19.
If you are using the D3RCAM, refer to “Connecting a Maintenance Terminal to the D3RCAM Craft Port” on
CONNECTING A MAINTENANCE TERMINAL TO THE SCU CRAFT PORT
Connect the VT100 compatible terminal or host computer to the interface port as follows:

TROUBLESHOOTING
Before the system tests are started, the fiber-optic network and DS3 lines at both ends must be connected. The
STATUS and DS3 ONLINE LEDs should be illuminated green.
Table 8 is intended as an aid in localizing trouble. If trouble is encountered with the operation of the D3LX, verify
that all installer connections are correct and that the options are configured properly. If technical assistance is
required, refer to “Appendix C - Product Support” on page 41. ADC strongly recommends that no internal
(component level) repairs be attempted on the module. The only field service should be a fuse or module
replacement. Any unauthorized adjustments or repairs may void the unit’s warranty.
