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 mo dule converts the optical sign al 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.

4 August 30 , 20 02 D3LX CO and RMT Modules

LTPS-UM-8013-03 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 rem ote 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 between 10

-4

and 10

-10

(default is 10-6).

-6

to 10

-10

(default is 10-8). The optical switch threshold may be set

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 th e tr ans mi ssion 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—D3L X modules provide high spe ed ATM

services using D3LX at a fraction of the cost of an OC-3 multiplexer.

LTPS-UM-8013-03 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 installing D3LX modules, refer to “Installing a D3LX CO Module in an LEC” on page 9.

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.

1 Mount the panel in the rack. 2 Secure the panel to the rack by using the provided screws. 3 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 mo st 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 sl ot s 1-2 and 1-4 do not have cables.

For exampl e, a D3LX CO module plugged into slo t 1-1 of the chassis or in a 2 D3LX protected system:

• The DS3 receive cable plugs into the botto m 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 botto m 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.

4 From the rear of the panel, con nect the coax end of an ADC adapter cable to the DS3 IN (receive) conn ector.

The connector number must match the connector number on the front of the panel.

5 Connect the wire-wrap conversion block e nd 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.

connector. The connector number must match the connector number on the front of the panel.

7 Connect the wire-wrap conversion block en d 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 T1 and R1 LINE wire-wrap posts to prevent improper connection.

8 Repeat this entire procedure for each D3LX module installed.

INSTALLING A D3LX CO MODULE IN AN LEC

Avoid exposure to invisible laser radiation.

• Do not look into the end s of any o ptical fib er or directly into the m odule fib er connec tors 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 d i stribution 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 baff le/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.

POWER VERIFICATION

Verification of Electrical DS3 Power Level

1 Apply power to the D3LX CO. 2 Attach the fiber patch cord from the D3LX CO to a meter. 3 Confirm that the readings are within the specification (-5 dBm to -23 dBm).

If the reading is not within the specification, check all fiber-optic connections to the D3LX CO. If the reading is still not within the specification, replace the module.

4 Once the readings are within specification, disconnect the patch cord from the meter.

Now that the DS3 power level meets optical specifications, verify the D3LX CO module.

12 August 30, 2002 D3LX CO and RMT Modules

LTPS-UM-8013-03 Installing a D3LX CO Module in an LEC

Verification of D3LX CO Optical Power

1 Connect an attenuator in series:

• Connect a patch cord from the meter to the attenuator.

• Connect a meter patch cord from the attenuator to the module.

2 Using the retaining latch, press the module into the chassi s until it is properly seated. 3 Is the STATUS indicator lit green?

• If Yes, continue to next step.

• If No, repeat steps 1 through 3 with a new D3LX CO module.

4 On the APU, as shown in Figure 6 on page 11, press the LMPTST/APS pushbutton. Did all D3LX CO

indicators light?

• If Yes, continue to next step.

• If No, repeat steps 1 through 3 with a new D3LX CO module.

The module laser is transmitting when power is applied to the module.

5 Confirm that the transmit power is -7 dBm ± 2 dBm.

If the reading is not within this specification, replace the module.

6 Reduce the voltage on the attenuator and confirm that the receive dynamic range is -5 dBm to 123 dBm.

If the reading is not within this specification, replace the module.

Verify that unit is completely disconnected from the chassis connectors before removing the optical fiber from the plug-in unit. Verify that the far end transmitter is off before proceeding. Exposure to invisible laser radiation from the optical fiber is possible if the far end transmitter is transmitting. Verify that all LEDs are off (not illuminated).

7 Release the retaining latch on the D3LX CO module and slide the module out about 3 inches. 8 Disconnect the meter patch cord from the D3LX CO module. 9 Route the fiber out the top of the chassis and adjust as required to remove any excess slack.

10 Guide the fiber with one hand while sliding the module slowly back into the chassis.

Always allow sufficient fiber length to permit routing without severe bends. Fibers may be permanently damaged if bent/curved to a radius of less than 1.5 inches (3.81 cm).

11 Using the retaining latch, press the module into the chassis until it is properly seated. 12 Did the STATUS indicator light green? (If ther e is no DS3 signal p resent, th e OPT FAIL indicator is lit red.)

• If Yes, continue to next step.

• If No, repeat steps 1 through 10 with a new D3LX CO module.

13 If this is to be a DS3 protected system, repeat the preceding steps to install the protect module in the slot

adjacent to the working module.

14 Repeat entire procedure for each D3LX CO module to be installed. 15 Store excess fiber at the fiber storage device specified in the work instruction.

POWER VERIFICATION

Verification of Electrical DS3 Power Level

1 Apply power to the D3LX RMT. 2 Attach the fiber patch cord from the D3LX RMT to a meter. 3 Confirm that the readings are within the specification (-5 dBm to -23 dBm).

If the reading is not within the specification, check all fiber-optic connections to the D3LX RMT. If the reading is still not within the specification, replace the module.

4 Once the readings are within specification, disconnect the patch cord from the meter.

Now that the DS3 power level meets optical specifications, verify the D3LX RMT module.

LTPS-UM-8013-03 Instal ling a D 3LX R MT Module in a Remote Cabinet

Verification of Optical Power

1 Connect an attenuator in series:

• Connect a patch cord from the meter to the attenuator.

• Connect a meter patch cord from the attenuator to the module.

2 Using the retaining latch, press the module into the chassis until it is properly seated. 3 Is the STATUS indicator lit green?

• If Yes, continue to next step.

• If No, repeat step s 1 through 3 w ith a new D3LX RMT modul e.

4 On the APU, as shown in Figure 9 on p age 15, press the LMPTST/APS pushbutton. Did all D3LX RMT

indicators light?

• If Yes, continue to next step.

• If No, repeat steps 1 through 3 with a new D3LX RMT module.

The module laser is transmitting when power is applied to the module.

5 Confirm that the transmit power is -7 dBm ± 2 dBm.

If the reading is not within this specification, replace the module.

6 Reduce the voltage on the attenuator and confirm that the receive dynamic range is -5 to -23 dBm.

If the reading is not within this specification, replace the module.

7 Release the retaining latch on the D3LX RMT module and slide the module out about 3 inches. 8 Disconnect the meter patch cord from the D3LX RMT module.

The D3LX RMT module optical power level specification is now verified.

9 Route the fiber out the top of the chassis and adjust as required to remove any excess slack.

10 Guide the fiber with one hand while sliding the module slowly back into the chassis.

Always allow sufficient fiber length to permit routing without severe bends. Fibers may be permanently damaged if bent/curved to a radius of less than 1.5 inches (3.81 cm).

11 Using the retaining latch, press the module into the chassis until it is properly seated. If there is excessiv e

resistance, withdraw the module and check for alignment or obstructions.

12 Did the STATUS indicator light green? (If ther e is no DS3 signal p resent, th e OPT FAIL indicator is lit red.)

• If Yes, continue to next step.

• If No, repeat steps 1 through 10 with a new D3LX RMT module.

13 If this is to be a DS3 protected system, repeat the preceding steps to install the protect module in the slot

adjacent to the working module.

14 Repeat entire procedure for each D3LX RMT module to be installed.

PROVISIONING

In D3LX systems, provisioning occurs automatically if a remote module is inst alled. 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-fr iendly 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 p rov isioning, 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 p rovisionin g databas e up to 24 hours after power is los t.

The following items are configured during provisioning:

• Protect or Non-Protect operation

-6

-10

• BER Minor Alarm Threshold (range, 10

• BER Switch Threshold (range, 10

• Equipped/Unequipped state

• Line State – In-Service (IS) – Out of Service (OOS)

-4

to 10

-10

)

• Alarm reporting options. For more information, see “Alarm Setting During Provisioning” on page 19.

• Line Buildout (range: two segments between 0 - 450 ft)

LTPS-UM-8013-03 Setting Up System Options

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 monitoring equipment. For more information on alarms, see “Configuring D3LX Alarms” on page 25.

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 Ter minal to the D3RCAM Craft Port” on

page 20.

CONNECTING A MAINTENANCE TERMINAL TO THE SCU CRAFT PORT

Connect the VT100 compatible terminal or host computer to the interface port as follows: 1 For initial setup, connect the local maintenance terminal to the SCU craft port (on front panel). After

configuration, the SCU may be con nected to ports 2 o r 3 on the back plane of the LEC. For more informat ion on Ports 2 and 3 located on the LEC, refer to Soneplex Loop Extender System Operation and Maintenance Manual, ADCP-61-494. See Table 3 for chassis port description s.

Troubleshooting LTPS-UM-8013-03

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.

MATING

Mate the SC and FC connectors by inserting the connector into the adapter and aligning the connector key with the adapter key slot as follows:

• FC connectors—Align the housing key with the slot in the adapter. Push the connector into the adapter and

screw the threaded cap clockwise onto the adapter to complete the connection.

• SC connector—Align the housing key with the slot in the adapter. Push the connector into the adapter until

a click is heard/felt, indicating that the latching system is engaged. When connector is fully engaged, the white stripes on the sides of the connector housing should be hidden inside the adapter.
