Overview

Yeastar EX08 Expansion Board for P560 and P570 IP PBX
The Yeastar EX08 expansion board is engineered to extend the functionality of compatible IP PBX systems with a flexible, modular approach. Designed specifically for the P560 and P570 platforms, it introduces additional connectivity options through multiple onboard module slots and panel interfaces. This enables businesses to scale their telephony infrastructure efficiently while adapting to evolving communication needs.

Description

The Yeastar EX08 provides a practical way to enhance PBX capacity without replacing existing hardware. With four onboard module slots and eight RJ11 ports, it supports a wide range of telephony modules, allowing integration of analog, ISDN, and cellular connectivity. Its modular architecture gives administrators the freedom to configure systems based on current requirements while maintaining room for future expansion. Suitable for growing organisations, the EX08 ensures reliable performance and seamless compatibility with Yeastar P560 and P570 systems.

Features

Flexible Expansion for Growing Communication Needs
The EX08 board allows tailored system configuration by supporting multiple module types. Whether the requirement is additional analog lines, GSM connectivity, or ISDN integration, the board accommodates diverse deployment scenarios. This flexibility reduces the need for multiple standalone devices and simplifies overall system architecture.

Deployment capacity varies depending on the PBX model:

• P560 supports one EX08 expansion board
• P570 supports up to two EX08 expansion boards

This scalability ensures that businesses can expand incrementally without overhauling their entire communication system.

Compatibility and Module Support
The EX08 is built to integrate seamlessly with supported Yeastar systems and modules, ensuring stable and consistent operation across deployments.

Supported systems:

• Yeastar P560 IP PBX
• Yeastar P570 IP PBX

Supported modules:

• S2 Module
• O2 Module
• SO Module
• B2 Module
• GSM Module
• 3G Module
• 4G LTE Module

Technical Details and Interface Capacity
For environments requiring clear technical parameters, the EX08 provides a balanced mix of interface density and modular flexibility:

• Part Number / SKU: YST-EX08
• RJ11 ports: 8
• Onboard module slots: 4
• Panel interfaces: 8
• Compatible systems: P560 and P570

These specifications make it suitable for mid-sized to larger deployments where both scalability and structured connectivity are required.

Efficient System Customisation
The modular design of the EX08 simplifies system upgrades and adjustments. Instead of replacing core PBX hardware, users can add or swap modules to match changing communication demands. This approach reduces downtime and preserves investment in existing infrastructure.

By incorporating the YST-EX08 into a Yeastar PBX environment, organisations gain a controlled and cost-effective way to expand telephony capabilities while maintaining system reliability.
