2.    Cisco 3925E: The Cisco 3925E router inherits its features from the Cisco 3925 router; it has only got 3 Enhanced High-Speed WIC & on-board digital signal processor slots compared to the Cisco 3925 Integrated Services Router that consists of 4 slots.

3.    Cisco 3945: The Cisco 3900 Series router has a modular Service Performance Engine (SPE) 150 which can also be upgraded for higher performances as the next-generation WAN systems evolve. It has 3 integrated Ethernet ports (10/100/1000 Mbps) with 2 ports of RJ-45 or SFP connectivity capability and up to 4 service module slots.

4.    Cisco 3945E: Apart from the 3 improved high-speed WIC slots and 3 digital signal processor slots on board. Most of the features remain as that of the Cisco 3945 Integrated Services Router.

In terms of security, all the four types of the Cisco 3900 Series Router offer identity management or administration through the AAA (authentication, authorization and accounting) and public key infrastructure coupled with integrated threat control using firewall, IPS, Cisco IOS firewall & content filtering and a hardware-accelerated VPN encryption that is embedded for secure collaborations.

They also help networking professionals deploy new IOS services easily and quickly through the universal IOS image.

The Cisco 3900 Integrated Services Router is the best option to migrate to if at all you have been using the Cisco 3800 Series Router since their sale by Cisco ended though Cisco still continues to give software maintenance and support until October 31, 2014 and October 31, 2016 respectively. That should not be a scare though –as PC Wholesale stocks cisco router memory for the Cisco 3800 Series Routers and the Cisco 3900 Series Router.
