CarpeStar NGN Switching Platform​

Softswitching Technology

Based on distributed switching/control layer, SPBX separates call controls from application layers, and could be seamlessly compliant with multiple communication devices and add applications on effortlessly.

Multimedia Convergence

Adopt 1000M-Ethernet switching chipset, SPBX’s media stream exchanges in IP-packets, and access to soft-switching system via Media Gateway Controller, ensuring high-level applications are streamlined.

High Scalability

Flattening architectures based on Soft-Switching ensures unlimited expandability from low density and high density. Modular design allows for easy configurations, system upgrading or general maintenance.

Diverse Media Resources

Support high-capacity voice playback and Codecs, conferencing, faxing and video; Support T.38/T.30; Set up Built-in IVR and ACD applications, with EXT IVR server or GUI management.

Standard TSAPI Interface

With standard TSAPI, the SPBX could be compatible with existing TSAPI-based call center and other applications, which greatly reduces development costs and shortens time to market.

Embedded Switching Application

SPBX possesses a complete range of switcher features, and helps set up efficient enterprise communication and call center systems, without developing any additional PBX software.

Telco Grade Reliability

Dual power system with standby redundancy; Intelligent cooling system reassures telco robustness; Special ash cleaner protects against dust accumulation; Internal temperature controller and alerts.
