Mitel DSP module SM-DSPC2 (2-chipset) 20351208 for telephony processing

Mitel DSP module SM-DSPC2 (2-chipset) is a dedicated digital signal processing board designed for Mitel telephony platforms. The board integrates two DSP chipsets to handle voice encoding and decoding, conferencing, and real-time call processing tasks. Intended for installation in compatible Mitel systems, the module increases media-handling capacity and reduces host CPU load by offloading audio processing to specialised hardware.

Advantages

The dual-chipset design provides increased parallel processing for multiple voice channels and conferencing sessions, improving overall system throughput. Hardware-based signal processing ensures consistent latency and predictable audio performance under heavy call loads. The module follows Mitel platform integration requirements, enabling straightforward replacement or expansion in supported chassis and blade systems. By offloading DSP tasks, it helps maintain system responsiveness and supports complex features such as transcoding and echo cancellation implemented in firmware.

Suitable for

• Enterprise telephony systems requiring additional media-processing capacity
• IP PBX platforms that support hardware-based DSP expansion
• Deployments needing multi-party conferencing and real-time voice processing
• System upgrades where host CPU offload is necessary to maintain call quality

Key specifications

• Dual digital signal processor chipsets for parallel voice processing
• Support for voice encoding/decoding and conferencing functions
• Designed for insertion into compatible Mitel platform slots or modules
• Hardware offload of real-time audio tasks to reduce host processor load
• Provides predictable low-latency audio handling under load

How to use

Install the DSP module into a supported Mitel chassis or blade slot following the platform’s hardware installation procedures. Ensure the system is powered down or follow hot-swap guidance from the platform documentation if supported. After physical installation, verify firmware compatibility and enable the module via the system management interface so the host can delegate media-processing tasks to the board. Monitor system logs and management tools to confirm the module is recognised and that voice channels are being processed by the DSP hardware.

Recommendations

Before installation, consult the target Mitel platform documentation to confirm compatibility, required firmware versions, and any configuration steps. Plan capacity changes considering the number of simultaneous channels and conferencing requirements to ensure the module meets expected load. Keep system firmware and management software updated to benefit from performance and interoperability fixes related to DSP functionality.
