## Long description

Yeastar EX08 is an expansion card that adds eight telephony ports and four flexible module slots for S2, O2, SO, BRI and GSM interfaces.

Compatibility with Yeastar platforms ensures coordinated signaling and management for unified configuration and monitoring.

Small to medium business PBX expansions where extra analog or digital trunks are needed

How to use
Install the EX08 expansion card into a compatible Yeastar PBX chassis following the vendor’s installation procedure. Populate the four module slots with the required interface modules (S2, O2, SO, BRI or GSM) according to line and network requirements, then connect external trunks or antennas as applicable.
