Where to Deploy VoIP and Legacy PBX Phone Systems in an Office Building

Deploying communication systems in a modern office building requires careful planning to ensure that the network infrastructure can handle both VoIP and legacy PBX phone systems efficiently. This article discusses the best practices and common locations for these systems and explains why certain areas of the office building are more suitable than others.

Introduction to VoIP and Legacy PBX Phone Systems

VoIP (Voice over Internet Protocol) and legacy TDM (Time Division Multiplexing) PBX are two types of communication systems that support voice connectivity in a corporate environment. VoIP leverages the internet to send voice data, while legacy PBX systems traditionally use dedicated copper loops or T1 lines for voice communication. Understanding the differences between these systems is crucial for effective deployment.

VoIP Deployment in the Server Room

The server room is typically the best location for deploying VoIP systems due to its proximity to the internet and the necessary network equipment. Here are the key reasons why the server room is ideal for VoIP:

Proximity to Ethernet Drops: In a typical office setup, the server room is equipped with numerous Ethernet drops, which provide the necessary connectivity for VoIP phones and other network devices. Data Network Compatibility: VoIP systems operate on the data network, making the server room a natural location for deployment. This setup ensures that the voice traffic is handled along with other data traffic with minimal performance impact. Centralized Management: Having the VoIP system colocated in the server room allows for easier management and maintenance, ensuring that the system remains reliable and up-to-date with the latest network configurations.

Legacy PBX Deployment in the Exchange Room

The exchange room is a traditional location for legacy PBX systems due to its central position in the office building and its proximity to key infrastructure. Here are the reasons why the exchange room is suitable for legacy PBX:

Historical Integration: Legacy PBX systems were designed to integrate with old-school phone lines, such as T1 or copper loops, which often enter the building at the exchange room. Direct Access to PSTN: The exchange room is generally where punch blocks and other hardware are located, making it easier to connect to the Public Switched Telephone Network (PSTN) and facilitating call traffic between the PBX and external lines. Physical Security: The exchange room is usually a secure area with limited access, providing a safe environment for sensitive equipment.

Comparison of Server Room and Exchange Room

While the server room is optimal for VoIP due to its integration with the data network and proximity to Ethernet drops, the exchange room is better suited for legacy PBX due to its historical and technical integration with legacy phone lines and its role in connecting to the PSTN.

Understanding these differences can help you make the right decisions when deploying both VoIP and legacy PBX systems in your office building, ensuring that your communication infrastructure is both reliable and efficient.

Conclusion

The placement of VoIP and legacy PBX systems in an office building is crucial for effective communication. By deploying VoIP in the server room and legacy PBX in the exchange room, you can leverage the strengths of each system to provide a seamless and robust communication experience for your employees.
