Additionally, this item supports features such as transcoding, conferencing, and voice activity detection (VAD). It also supports Cisco's IOS voice and video services, including Cisco Unified Communications Manager Express, Cisco Unity Express, and Cisco Unified Border Element.
It is a plug-in module and can be installed on the motherboard of the supported routers for adding voice and video capabilities.
Features and Benefits
The model Cisco module is designed to provide high-density voice and video digital signal processing (DSP) capabilities for Cisco routers and other networking devices. It has a capacity of 256 channels, allowing it to support a large number of simultaneous voice or video calls.
In terms of performance, the PVDM3-256 is capable of handling a high number of simultaneous voice or video calls, depending on the codec and complexity of the call. It supports a wide range of voice and video codecs, including G.711, G.729, G.722, and H.264. It also supports advanced features such as echo cancellation, noise reduction, and jitter buffer management which improves the overall quality of the call.
This item can also be used for other applications such as conferencing, transcoding, and security features such as VPN and firewall. It has a high-performance DSP architecture that supports the concurrent processing of multiple voice and video codecs.
The module is also designed to be highly reliable and scalable, with built-in redundancy and failover capabilities. It can be easily integrated with Cisco's IOS software and is compatible with a range of Cisco routers and other devices, including the Cisco 2900, 3900, and 4000 Series Integrated Services Routers.
Resiliency and High Availability
The PVDM3-256 Cisco module is designed to provide resiliency and high availability for voice and video digital signal processing capabilities in Cisco routers and other networking devices.
One way it achieves this is through the use of redundant power supplies and fans, which help to ensure that the module continues to function even if one of these components fails. This helps to minimize downtime and ensure that voice and video calls can continue to be handled even in the event of a failure.
Another way that the model provides resiliency and high availability is through the use of load balancing and failover capabilities. This allows the module to distribute the workload across multiple channels, ensuring that no single channel is overwhelmed. Additionally, in case of failure of one of the channels, the load is automatically shifted to other channels to ensure continuity of service.
Additionally, this item supports advanced conferencing features such as multiparty conferencing, which allows multiple parties to participate in a conference call or video call simultaneously, even if one of the participants' connection fails, the conference can continue.
Additionally, The model can work in a High Availability setup by having a redundant module, if one module fails the other will take over the processing seamlessly, ensuring continuity of service.
