- Voice compression and decompression
- Silence suppression and voice activity detection
- Tone generation and detection
- Echo cancellation
- Fax relay
- Voice and video conferencing
This module is also capable of supporting advanced voice features such as transcoding and conferencing, which can help reduce the amount of bandwidth required to transmit voice calls.
Features and Benefits
The performance of the model Cisco 64 channel high-density voice DSP module depends on several factors, including the specific Cisco router it is installed in, the types of voice and fax features that are being used, and the number of simultaneous calls that are being handled.
The PVDM4-64 module provides a significant increase in the number of simultaneous voice or fax calls that can be handled in a single Cisco router. By providing 64 channels of DSP resources, the model allows for up to 64 simultaneous voice or fax calls, which is a significant increase over the DSP resources that are typically available on Cisco routers without PVDM4 modules.
This model DSP module also provides advanced voice and fax features that can help to improve call quality and reduce the amount of bandwidth required for voice calls. For example, the module supports voice compression and decompression, which can help to reduce the amount of bandwidth required to transmit voice calls. It also supports silence suppression, which can help to reduce the amount of background noise in calls, and echo cancellation, which can help to improve call quality.
The model module also supports advanced conferencing and transcoding features, which can help to improve the quality of calls and reduce the amount of bandwidth required for video and voice conferencing.
Additionally, this DSP module provides a high-performance architecture with a multi-core DSP and improved memory which help to deliver real-time voice and video processing.
