D9 wire wrapping DDF block for A8 connector

    Descriptions    

12 systems D9 DDF block 120Ω (TP-1306-D9) is used on Digital Distribution Frame (DDF) working as the interface for E1/T1 (2Mbps) where the 120ohm shielded twisted pair cable has to be interconnected, cross-connected and organized. It also features monitoring of signals for supervising digital transmission equipment.

 
In fixed networks the DDF should be placed in a centralized location and serve as the interface between the exchange and transmission equipment 
 
In mobile networks, the DDF serves as the interface between a MSC (Mobile Service Switching Center) or BSC (Base Station Controller) and the transmission equipment.

    Main Features    

• Modular Design: DDF blocks have a modular design, allowing for easy expansion or customization as the network's requirements change.
• Cable Management: DDF blocks typically offer cable management features, such as cable routing channels, cable ties, and cable entry/exit points, to ensure organized and neat cable installations.
• Termination Points: DDF blocks have termination points where incoming and outgoing cables can be connected.
• Front Access: DDF blocks are designed with front access, which can be useful for maintenance and cable management. Front access allows for easy connection changes.
• Ease of Installation: Consider the ease of installation and setup of the DDF block, especially if it requires complex configurations.
• Cross-Connect Density: a high cross-connect density is essential to accommodate a large number of cross-connections between cables and equipment.
