Relationship of SCS, ISP, OSP, DAS

SCS: Structured Cabling System 【Or Premises Distribution System(PDS)】

A structured cabling system is a standardized, systematic approach to telecommunications cabling within a building or campus. It provides a flexible and organized infrastructure for voice, data, video, and multimedia signals.

ISP: Inside Plant

ISP refers to the cabling and equipment within a building

OSP: Outside Plant

OSP refers to the cabling and infrastructure outside the building connecting to the wider network or other buildings.

DAS: Distributed Antenna System

DAS is a network of antennas used to improve cellular and Wi-Fi coverage within a building or area.

Structured Cabling System

• Organization

It's a standardized, organized way to manage cabling, unlike traditional point-to-point systems.

• Subsystems

It consists of subsystems (e.g., horizontal cabling, backbone cabling) that work together to create a comprehensive network.

• Standards

It adheres to standards like TIA/EIA-568, ensuring compatibility and reliability.

• Flexibility

It allows for easy changes and upgrades to the network without disrupting the entire system.

• Components

It includes elements like patch panels, switches, and trunks that facilitate connectivity and management.

• Benefits

It offers improved performance, scalability, and manageability. 

ISP (Inside Plant)

• Location: Cabling and equipment within a building.
• Examples: Patch panels, switches, cables, and jacks within the building. 

OSP (Outside Plant)

• Location: Cabling and equipment outside the building.
• Examples: Underground or aerial cables, support structures like poles and trenches.
• Purpose: Connects the building's network to the broader network or other buildings. 

DAS (Distributed Antenna System)

• Purpose: Improves wireless signal strength and coverage within a confined area.
• Components: A network of antennas, cables, and other equipment.
• Applications: Used in buildings, stadiums, and other areas with poor cellular or Wi-Fi reception. 

Relationship of CSC/ISP/OSP/DAS

• A structured cabling system can be used to support both ISP and OSP networks.
• The structured cabling system provides the foundation for connecting the inside network (ISP) to the outside network (OSP).
• DAS often relies on a structured cabling system to distribute the wireless signals throughout a building or area.
