Cisco2901-SEC/K9 is this limited to only 1 site to site or it allows for multiple site to site connections?
It allows 225 IPsec VPN connections, and with the HSEC-K9 license, the ISR G2 router can go over the curtailment limit of 225 tunnels maximum.
Will the Cisco 2901-SEC/K9 hold the full Internet Routing Table when having BGP Peering with an ISPF?
The answer is YES assuming the 2901-SEC/K9 has at minimum 2 Gigabytes of DIMM. 1.14 RIB is roughly 1.5 Gigabytes in size and growing daily.
Does it support multicore processor?
Yes, all Cisco 2900 series model support multicore processor.
Does CISCO2901-SEC/K9 have integrated SFP slots?
No, Cisco 2901 and 2911 do not have integrated SFP slots. But 2921 and 2951 have one.
Does CISCO2901-SEC/K9 support USB console?
Yes, all Cisco 2900 series model support USB console.
Does it support Multigigabit fabric?
Yes, multigigabit fabric is supported in all Cisco 2900 series routers.
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
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.
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.
