The Cisco C2911 CME SRST K9 Datasheet is a critical document for understanding the capabilities and specifications of the Cisco 2911 Integrated Services Router (ISR) when configured with Cisco Unified Communications Manager Express (CME) and Survivable Remote Site Telephony (SRST) features, specifically the K9 software version. This datasheet outlines the features, benefits, and hardware/software requirements for deploying a robust and reliable voice and data network solution, especially in branch office environments.
Decoding the C2911 CME SRST K9 Datasheet
The Cisco 2911 ISR, when equipped with CME and SRST and running the K9 software, serves as a comprehensive solution for small to medium-sized businesses and branch offices requiring integrated voice and data services. CME provides IP telephony features directly from the router, eliminating the need for a separate call control server at smaller sites. SRST, on the other hand, provides call control backup in case of a WAN outage, ensuring that users can continue to make and receive calls even when connectivity to the central office is lost. The C2911 CME SRST K9 configuration offers a cost-effective and highly resilient communication platform.
The C2911 CME SRST K9 datasheet details supported features, scalability limits (e.g., the number of supported IP phones), and hardware specifications. Understanding these aspects is crucial for proper planning and deployment. Here are some key aspects often detailed in the datasheet:
- Voice Features: Call forwarding, call transfer, conferencing, and voicemail integration.
- SRST Capabilities: Automatic failover and fallback, maintaining essential telephony services during WAN outages.
- Security Features: Firewall, VPN, and intrusion prevention capabilities to protect the network.
Moreover, the datasheet outlines the various hardware options available for the Cisco 2911, including interface cards for connecting to different types of WAN links (e.g., T1/E1, Ethernet) and voice modules for connecting to traditional analog phone lines. A sample table showcasing module support looks like:
| Module Type | Description |
|---|---|
| VIC3-2FXS/DID | Two-port FXS/DID Voice Interface Card |
| EHWIC-1GE-SFP | One-port Gigabit Ethernet High-Speed WAN Interface Card |
To get the most comprehensive understanding of the capabilities and limitations of the Cisco 2911 CME SRST K9 solution, carefully review the official datasheet provided by Cisco. It contains critical information for design, implementation, and troubleshooting.
