CISCO2911-DC/K9, Cisco 2911 Router, 3xGE/4xEHWIC/512MB DRAM

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.

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 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.

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.
