The PVDM4-256 module for Cisco Integrated Services Routers is designed to provide scalable and reliable voice and video services for organizations of all sizes. This module features 256 channels of voice and video compression, allowing for a large number of concurrent voice and video sessions.
One of the key benefits of the PVDM4-256 module is its scalability. As the organization's communication needs grow, the number of channels can be increased by adding additional PVDM4 modules. This ensures that the system remains efficient and capable of handling the increasing demand for voice and video services.
The PVDM4-256 module is also highly reliable. It is designed to be used in demanding network environments, with robust hardware and software features that ensure high availability and fault tolerance. This reliability is further enhanced by the module's integration with the Cisco Integrated Services Routers, which provide a highly secure and resilient network infrastructure.
Deployment and Configuration- Insert the PVDM4-256 module into the appropriate slot in the Cisco router or switch.
- Connect the module to the network.
- Login to the router or switch and enter into the configuration mode by typing "enable" followed by the password.
- Enter the following command to confirm the module is recognized by the router or switch: "show diag".
- Enter the following command to configure the module for voice usage: "voice dsp farm profile 1 hardware dsp services dspfarm".
- Configure the number of DSP channels that the module will support: "voice dsp farm dsp services dspfarm maximum sessions 256".
- Configure the codecs that will be used by the module: "voice dsp farm dsp services dspfarm codec g711ulaw".
- Save the configuration by typing "write memory".
- Verify the configuration by typing "show voice dsp farm".
- Test the module by placing a test call to ensure that voice is processed by the PVDM4-256 module.
- Monitor the module performance by using the "show process cpu" command.
- Monitor the module usage by using the "show voice dsp farm statistics".
- Make any necessary changes to the configuration based on the results of the monitoring.
The PVDM4-256= (PVDM4-256= Cisco Voice Digital Signal Processor Module) is a hardware module used in Cisco routers and switches to process voice signals and support voice and video applications.
In terms of security, the PVDM4-256= module supports encryption algorithms such as Advanced Encryption Standard (AES), secure real-time transport protocol (SRTP), and secure shell (SSH) to secure voice and video communications.
AES encryption provides secure data encryption for voice and video communications by using a symmetric key algorithm that encrypts and decrypts data.
SRTP is a security protocol used to protect voice and video communications from eavesdropping, tampering, and replay attacks. It encrypts the RTP data and provides authentication and encryption for the RTP payload.
SSH is a secure protocol used to remotely access and manage network devices securely. It provides secure encrypted communications between two untrusted hosts over an insecure network.
The PVDM4-256= module also supports other security features such as Virtual Private Network (VPN) tunnels, access control lists (ACLs), and network address translation (NAT) to secure network communications.
