Cisco
Integrated Services Routers Generation 2 (ISR G2) offer data functionality
through Gigabit Ethernet ports and security functionality with a virtual
private network (VPN) accelerator on the motherboard. Additional security
features are available with add-on hardware and software.
Cisco 2900 series
routers and Cisco 3900 series
routers also provide voice IP telephony with digital signal processor (DSP)
capability; and voice gateway, DSP farm, IP-to-IP gateway, Cisco Unified
Communications Manager Express (CUCME) via Cisco IOS. Cisco Unity Express (CUE)
is provided through the use of add-on hardware.
This series of ISRs have new slots that support next
generation Enhanced High-Speed WAN Interface Cards (EHWICs), Internal Services
Modules (ISMs), Packet Voice Data Modules (PVDM3s), Service Modules (SMs), and
Services Performance Engines (SPEs).
Access to the Cisco Multi-Gigabit Fabric (MGF) facilitates connection
between switch ports on the ISR without utilizing all of the external ports. A
logical GE interface on the ISR connects external and internal modules through
the MGF for improved LAN and WAN switching.

Only Advanced Capability CompactFlash
(CF) purchased from Cisco operates in Cisco 2900 series and Cisco 3900 series
ISRs. Legacy CF can impact and severely degrade performance in these routers.
When legacy CF is inserted, the following error message appears:
WARNING: Unsupported compact flash detected. Use of this card during normal operation can impact and severely degrade performance of the system. Please use supported compact flash cards only.
