Modularity Features and Benefits:
The Cisco 2900 Series provides significantly enhanced modular capabilities offering investment protection for customers. Taking advantage of common interface cards across a network greatly reduces the complexity of managing inventory requirements, implementing large network rollouts, and maintaining configurations across a variety of branch-office sizes.
Cisco Service Module
• Each service module slot offers high-data-throughput capability:
• Up to 4 Gbps aggregate toward the route processor.
• Up to 2 Gbps aggregate to other module slots over MGF.
• Service module (SM) slots are highly flexible with support for double-wide service modules (SM-Ds), which are Service Modules that require two SM slots. SM-Ds in the Cisco 2921 and 2951 provide flexibility for higher-density modules.
• A service module slot replaces the network module and the extension module for voice/fax (EVM) slots and is offered on Cisco 2911, 2921, and 2951 ISRs.
• An adapter module enables backward compatibility with existing network modules, enhanced network modules (NMEs), and EVMs.
• Service module slots provide twice the power capabilities relative to the network-module slots, allowing for flexibility for higher-scale and better-performance modules.
• Power to service module slots can be managed by extensions similar to the Cisco EnergyWise framework, so your organization can reduce energy consumption in your network infrastructure. Full EnergyWise support will be available in future software releases.
Cisco Enhanced High-Speed WAN Interface Card (EHWIC)
• The EHWIC slot provides enhancements to the prior generation's high-speed WAN interface card (HWIC) slots while provide maximum investment protection by natively supporting HWICs, WAN interface cards (WICs), voice interface cards (VICs), and voice/WAN interface cards (VWICs).
• Four integrated EHWIC slots on the Cisco 2901, 2911, 2921, and 2951 allow for more flexible configurations.
• Each HWIC slot offers high-data-throughput capability:
• Up to 1.6 Gbps aggregate toward the route processor.
• Up to 2 Gbps aggregate to other module slots over the MGF.
• Flexibility to support double-wide modules is enabled by combining two EHWIC slots. Up to 2 doublewide HWIC (HWIC-D) modules are supported.
Cisco High-Density Packet Voice Digital Signal Processor (DSP) Module (PVDM3) Slots on Motherboard
• PVDM3 slots natively support PVDM3 modules, providing support for richer density for rich-media voice and video.
• Each PVDM3 slot connects back to the system architecture through a 2 Gbps aggregate link through the MGF.
• Investment protection for PVDM2 modules is supported through an adapter module.
• Power to the PVDM slots can be managed by extensions similar to the Cisco EnergyWise framework, so your organization can reduce energy consumption in your network infrastructure. Full EnergyWise support will be available in future software releases.

Q: What is L-FL-CME-SRST-25 function?
A: Cisco Unified Survivable Remote Site TelephonySRST is a feature of Cisco IOS software that allows the IP phones at the remote site cannot contactthe central call manager can still supportbasic traffic handling capacity
Q: FL-CME-SRST-25 does this 25 means this license only supports 25 IP Phones?
A: NO, this number means Cisco Survivable Remote Sites.The number of Phones Supported is depended on the Router model.
For example: 2901 supports 35 IP Phones, 2911 supports 50.
Q: For an ISRG2 Cisco Routers HWIC Cards, are they limited by the respective number of supported HWIC slots or by the number of routed ports they will provide?
A: Yes, based on my research, a Cisco 2911 has four (4) HWIC slots, but it can only support two(2) HWIC-2FE or four(4) HWIC-SFP-CU. With HWIC-2FE, you can have a total of 7 Routed Ports, including the integrated routed ports of the Router and six (6) routed ports if you use four HWIC-SFP-CU.
Q: Looking at CISCO 2900 series data sheet, there is a sentence under "Benifits" The Cisco 2900 Series enables deployment in high speed WAN environments with concurrent services enabled up to 75 Mbps What does this mean? The interface is 1Gbps, why 2900 is only enabled up 75 Mbps?
A: That means the router running services (IE Zone-based firewall, NAT, NBAR, etc) can maintain 75Mb of traffic throughput. If you don't want to run any services, the throughput is more than 100Mb so a gig interface is necessary.
Q: I'm currently using a 2811 as our internet/BGP border router with receiving full routes, the current bandwidth is 15 meg and planning to upgrade to 30 meg. Will the current 2811 handle the bandwidth and the full BGP routes at the same time? I was thinking to ask our management to upgrade to at least a 2911 ISR G2 since the current router is old.
A: 2911 should be able to handle 30 Mbps. The main problem is the full BGP routing table. And this can alleviated if you load up the router "up to the eyebalss" with DRAM. Personally, I'd prefer something chunkier, like 3925/3925E, for future proofing.
