The Cisco 2900 series integrated services router offers embedded hardware encryption acceleration, voice- and video-capable Digital Signal Processor (DSP) slots, intrusion prevention, call processing, voice mail, and application services. CISCO2911-SEC/K9 is almost the same as CISCO2911, except that it offers Security bundle.

Can I must purchase the PVDM to get the voice function?
Yes. Cisco 2900 series need to installed PVDM and related license to get the voice function.
What is the SRST?
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
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?
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.
What is an enhanced high-speed WAN interface card (EHWIC)?
The EHWIC is an updated and enhanced version of the HWIC already available with existing integrated services routers. It offers greater speeds and higher port density than the current HWIC. EHWIC slots can support modules that provide both product-based Cisco Inline Power and PoE. EHWICs are available in two form factors: a singlewide form factor that takes up 1 slot and a doublewide form factor that takes up 2 slots. Note: You can combine two EHWIC slots into one bigger slot (EHWIC-D) by removing the center rail between two individual slots. The EHWIC slot is also backward-compatible with existing HWICs, voice interface cards (VICs), and WICs.
What is an internal service module (ISM)?
The ISM is the evolution of the AIM slot available on earlier integrated services routers. It provides additional capabilities such as increased throughput and integration with the MGF in the integrated services routers generation 2. Note that existing AIMs will not work in the new ISM slot.
What module will replace the Cisco AIM-VPN Module?
There is currently no plan for any VPN acceleration ISM module. The integrated services routers generation 2 include built-in hardware acceleration for encrypted traffic, and in effect they already include AIM-VPN functions as part of the default platform hardware.
Can I reuse my existing PVDM2 DSP modules in the Cisco 2900 Series routers?
Yes. You can install PVDM2s on the motherboard PVDM slots using the PVDM adaptor cards (PVDM2-ADPTR). You can also insert the high-density voice network modules (NM-HDV2s) with PVDM2s into the service-module slots of the Cisco 2900 and 3900 Series routers by using the network module-to-service module adapter card (SM-NM-ADAPTR).
Can I reuse my TDM gateway interfaces on the Cisco 2900 Series platforms?
For the motherboard PVDM slots, the PVDM3 DSP modules offer the best DSP density - and these modules do not require adapter cards. For service-module slots, order the NM-HDV2, along with the network module-to-service module adapter (SM-NM-ADPTR), and PVDM2 DSPs.
Do the Cisco 2900 Series platforms have dedicated EVM slots similar to those on the Cisco 2800 Series?
No, the Cisco 2900 Series platforms do not have dedicated EVM slots, but they do support the EVM card in their service-module slots (unlike the Cisco 2800 platforms) with the network module-to-service module adapter (NM-SM-ADAPTR).
Can the PVDM2 and PVDM3 DSP modules coexist on the Cisco 2900 Series routers?
Yes, they can coexist as long as they are not both installed in the same domain. The motherboard PVDM slots form one domain and each service-module slot forms a separate domain. The motherboard domain can contain either all PVDM2 modules or all PVDM3 modules. A service-module domain can contain only PVDM2 modules housed by the NM-HDV2 carrier card. If a mix of PVDM2s and PVDM3s is detected on the motherboard, the PVDM2s are deactivated, allowing only the PVDM3s to be active. If PVDM2s are detected in service-module slots and PVDM3s are installed on the motherboard, then both continue to function in their own domain and coexist.
