Yeastar S-Series and P -Series Module EX08
The Yeastar EX08 Expansion Module is a hardware extension card that enhances the connectivity options of Yeastar S-Series and selected P-Series PBX systems. Designed for businesses requiring additional analog or digital interfaces, the EX08 provides modular flexibility by supporting a variety of interface cards. This makes it ideal for integrating legacy telephone lines, analog phones, or GSM/3G/4G networks into a modern VoIP environment.
Flexible Port Expansion with Modular Slots:
The EX08 module features four onboard module slots and one RJ21 port, allowing users to install different types of telephony interface modules based on their specific connectivity needs. Supported module types include FXO (PSTN), FXS (analog phones), BRI (ISDN), GSM/3G/4G, and E1/T1 (digital trunking). This level of flexibility makes the EX08 a valuable tool for hybrid deployments where VoIP coexists with traditional telephony infrastructure.
Support in P-Series PBX Systems:
For the P-Series appliance models, particularly the P560 and P570, the EX08 module extends connectivity in similar ways. When combined with appropriate interface modules, it enables the PBX to support analog trunks, legacy phone lines, and mobile network integration, providing a smooth transition from traditional telephony to modern VoIP. The ability to mix and match modules ensures that the P-Series can adapt to virtually any deployment scenario, from remote branch offices to large-scale unified communications environments.
Compatibility with S-Series PBX Systems:
In the Yeastar S-Series, the EX08 is compatible with the S100 and S300 models. When installed in these systems, it significantly enhances the PBX's capacity to connect with traditional telephony networks. For example, businesses can use FXO modules to connect to analog trunk lines or FXS modules to support legacy analog phones. Additionally, the RJ21 connector provides a high-density option for mass analog port deployment using a single cable, making the EX08 ideal for organizations with a mix of analog and digital requirements.
Ideal Use Cases for the EX08 Module:
The EX08 is particularly useful in hybrid telephony environments where businesses must maintain compatibility with existing infrastructure while adopting modern communication solutions. It supports use cases such as connecting to public telephone networks (PSTN), supporting analog desk phones, adding GSM backup for failover, or providing digital ISDN lines for enterprise-grade calling. Its modular design ensures that organizations can scale and adapt their PBX without unnecessary hardware replacement.
