The Cisco ISR G2s are part of the Cisco Borderless Network Architecture that enables business innovation and growth across all remote sites. The next-generation architecture delivers a new workspace experience by meeting the performance requirements for the next generation of WAN and network services, enabling the cost-effective delivery of high-definition collaboration at the branch office and providing the secure transition to the next generation of cloud and virtualized network services. Designed for optimal service delivery on a single platform, the new Cisco ISR G2 routers give businesses greater power to deliver a superior customer experience and deploy services “on demand” as business needs dictate—while reducing overall operating costs.
The Cisco ISR G2 router families include the following models listed from smallest to largest form factor:
• Cisco 800 Series Routers (Cisco 860, Cisco 880, Cisco 890)
• Cisco 1940 Series Routers (Cisco 1941, Cisco 1941W)
• Cisco 2900 Series Routers (Cisco 2901, Cisco 2911, Cisco 2921, Cisco 2951)
• Cisco 3900 Series Routers (Cisco 3925, Cisco 3945)
Different ISR G2 router models have form factors akin to the Cisco 1800, Cisco 2800 and Cisco 3800 series routers they are meant to replace. The ISR G2 routers introduce support for new hardware components including the following:
• More onboard Gigabit Ethernet ports
• Console over USB using a micro USB form factor
• Internal Services Modules (replaces AIM)
• Services Modules (replaces network modules)
• EHWIC slots (replaces HWIC slots)
• PVDM3 modules
The G2 platforms accommodate the following throughput:
• Cisco 1941/2910 - up to 25Mbps
• Cisco 2911 - up to 35Mbps
• Cisco 2921 - up to 50Mbps
• Cisco 2951 - up to 75Mbps
• Cisco 3925 - up to 100Mbps
• Cisco 3945 – up to 150Mbps
Cisco sells adaptors that allow older network modules to fit service module (SM) slots. PVDM2 modules can be inserted into PVDM3 slots by using a PVDM2 to PVDM3 adapter. The PVDM3 modules are optimized for video and include the following form factors:
• PVDM3-16
• PVDM3-32
• PVDM3-64
• PVDM3-128
• PVDM3-192
• PVDM3-256
Survivable Remote Site Telephony (SRST) and Cisco Unified Communications Manager Express (CUCME) support the following number of devices in the ISR G2 routers:
• 2901 – 35 CUCME / 35 SRST
• 2911 – 50 CUCME / 50 SRST
• 2921 – 100 CUCME / 100 SRST
• 2951 – 150 CUCME / 250 SRST
• 3925 – 200 CUCME / 730 SRST
• 3945 – 300 CUCME / 1200 SRST
Cisco IOS 15.0 supports the ISR G2 routers with a single universal image. Cisco reduced the feature sets to four individual features sets in Cisco IOS 15.0. The capabilities of the purchased feature sets will be unlocked when the license is applied to the router.
