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 remote D3LX module. APS is non-revertive and bidirectional and may be forced or disabled through the front-panel pushbuttons or the SCU software.
Preparing to Install D3LX Modules LTPS-UM-8013-03 PREPARING TO INSTALL D3LX MODULES Prior to installing D3LX modules in chassis confirm that: 6 • chassis are installed for each module (an LEC for the D3LX CO and a Four-Position Remote Terminal Cabinet or Two-Position QLX Remote BNC Chassis for the D3LX RMT). • a BNC Patch Panel with ADC adapter cables is installed in the CO rack and at the remote site. For more information about this operation, refer to “Installing the BNC Panel” on page 7.
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.
Installing the BNC Panel LTPS-UM-8013-03 6 From the rear of the panel, connect the coax end of an ADC adapter cable to the DS3 OUT (transmit). connector. The connector number must match the connector number on the front of the panel. 7 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.
LTPS-UM-8013-03 Installing a D3LX CO Module in an LEC 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.

Installing a D3LX RMT Module in a Remote Cabinet LTPS-UM-8013-03 INSTALLING A D3LX RMT MODULE IN A REMOTE CABINET 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.
LTPS-UM-8013-03 Installing a D3LX RMT Module in a Remote Cabinet 3 Locate the mounting slots designated for the D3LX RMT modules in the chassis. If protection switching is required, a working module installs in the first slot of a quad group, such as 1-1 or 2-1. The protection module installs in the slot to the right of the working module, slot 1-2 or 2-2. 4 Refer to Figure 9 for D3LX RMT module locations chassis and slot corresponding to the DS3 signal.

Provisioning 15 LTPS-UM-8013-03 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.
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.
