The ADC DSX-1 and DSX-1C Cross-Aisle Panel is a critical component in multi-lineup DSX-1 Systems, designed to streamline inter-bay wiring and enhance system organization. Its primary function is to serve as a termination field for tie cables that connect different bay lineups, thereby eliminating the need for individual overhead cross-connect wires that would otherwise span between lineups. This design significantly reduces wire congestion and simplifies cross-connect management.

Function Description:

The Cross-Aisle Panel acts as an intermediary connection point. In a typical setup, bay lineups are interconnected via tie cables terminated to these panels on each lineup. DSX circuits within separate lineups are then interconnected by installing cross-connect wires from each DSX circuit to the Cross-Aisle Panel in the same lineup. This approach facilitates a more organized and manageable wiring infrastructure, especially in large-scale DSX-1 systems.

ADC recommends two primary Cross-Aisle Panel cable designs:

1. Direct Cross-Aisle Wiring: In this configuration, all Cross-Aisle Panels are cabled between similarly numbered bays in each lineup. Cross-connect wires run from the originating Cross-Aisle Panel to the associated Cross-Aisle Panel in another lineup. This method often negates the need for a horizontal wireway in the originating bay, with the cross-connect extending to the terminating location, typically using a horizontal wireway in the second lineup.
2. Zoned Cross-Aisle Wiring: This design involves cabling Cross-Aisle Panels between the same bays within a zone and also between like-positioned bays across different zones. For instance, in a two-zone system, the first bays in each zone (e.g., all bay 1s and bay 11s) are interconnected. This method allows for the equal distribution of cable complements between sets of bays. With zoned cross-aisle design, jumpers utilize Cross-Aisle Panels in the originating bay (eliminating horizontal wireway needs there) to an associated Cross-Aisle Panel in the nearest terminating lineup. The cross-connect then extends within that lineup to the terminating location, using horizontal wireways unless the termination is within the same bay. Zoned cabling systems generally result in shorter jumpers and reduced horizontal jumper pileup.

The panel supports both front and rear cross-connect systems. In a front cross-connect DSX system, the front of the Cross-Aisle Panel is used for cross-connect jumpers, while the back connects tie cables between lineups. Conversely, in a rear cross-connect system, the back is used for cross-connect jumpers, and the front connects tie cables.

Important Technical Specifications:

• Terminations: Cross-Aisle Panels are available with either 50, 100, or 200 five-wire terminations. Additionally, 50 or 100 six-wire terminations are also offered.
• Mounting: The panels are installed in assigned bay locations using 12 – 24 × 1/2 inch mounting screws (ordered separately).
• Dimensions: A typical panel has a front view width of approximately 19.80 inches (50.3 cm) and a rear view width of 22.312 inches (56.7 cm). The overall width, including mounting brackets, is around 29.30 inches (74.4 cm). The height is approximately 1.60 inches (4.06 cm), with a maximum depth of 4.00 inches (10.16 cm) and a minimum depth of 3.00 inches (7.64 cm).
• Tie Cable Type: Recommended cable for cross-aisle ties is shielded twisted pair cable, 26 AWG, similar to AT&T 1249 cable. Separate cables should be used for each direction of the circuit, and the cable shield should be grounded at one end only.
• Cross-Connect Wire Type: Recommended cross-connect cable is 24 AWG conductor with independent twisted pairs and a binder wire, all twisted together.
• Maximum Cross-Connect Length: To ensure reliable signal levels and minimize digital signal losses, the recommended maximum cross-connect length, including cross-aisle cables, is 85 feet (25.90 meters). Cross-connections should always be made from OUT to IN and IN to OUT.
• Wiring Connections (Originating DSX Lineup):
  • TL (green wire) from DSX circuit to TL on cross-aisle tie circuit.
  • OUT (blue wire and blue-white wire) from DSX circuit to IN on cross-aisle tie circuit.
  • IN (orange and orange-white wire) from DSX circuit to OUT on cross-aisle tie circuit.
• Wiring Connections (Terminating DSX Lineup):
  • TL (green wire) from cross-aisle tie circuit to TL on DSX circuit.
  • OUT (orange and orange-white wire) from cross-aisle tie circuit to IN on DSX circuit.
  • IN (blue wire and blue-white wire) from cross-aisle tie circuit to OUT on DSX circuit.
• Color Scheme Detail: Every 5th circuit is typically white for easy identification.

Usage Features:

• Simplified Inter-Lineup Wiring: Eliminates the need for individual overhead cross-connect wires, leading to a cleaner and more organized installation.
• Scalability: Supports multiple lineup DSX-1 systems, making it suitable for expanding network infrastructures.
• Flexible Design Options: Offers both direct and zoned wiring configurations to accommodate different network designs and optimize jumper length.
• Clear Termination Fields: Provides dedicated termination points for tie cables and cross-connect wires, improving traceability and reducing installation errors.
• Removable Cable Tray: Features a removable cable tray for easier cable management (not mounted by ADC).
• Safety Admonishments: Includes clear safety warnings (Danger, Warning, Caution) regarding electrical shock prevention, especially when working in wet locations or during lightning storms, and emphasizes disconnecting lines before working with uninsulated lines or terminals.

Maintenance Features:

• Organized Wiring: The structured approach to wiring, especially with zoned systems, results in shorter jumpers and reduced pileup, simplifying maintenance and troubleshooting.
• Traceability: The unique numbering system and clear point-to-point wiring examples enhance circuit traceability, regardless of how circuits are provided.
• Jumper Removal Procedure: Provides a recommended method for removing discontinued jumpers by disconnecting each end, cutting off bare ends, and carefully pulling from wireways to avoid snagging or straining remaining jumpers.
• Cross-Connect Routing Rules: Specific routing rules are provided to ensure minimal wire congestion, optimal traceability, and ease of installation and maintenance. These rules dictate how jumpers should enter/leave bays from vertical wireways (left/right sides), use vertical rings for intrabay cross-connects, and horizontal wireways for interbay cross-connects, distinguishing between upper and lower horizontal wireways based on the jumper's origin in the cross-connect field.
• Installation Drawing: Each panel is shipped with an installation drawing that defines specific input and output terminations, aiding in correct installation and future maintenance.

The ADC DSX-1 and DSX-1C Cross-Aisle Panel is a robust solution for managing DSX-1 inter-lineup connections, promoting an organized, efficient, and maintainable network infrastructure.
