Cisco 1941W VS Cisco 1941 VS Cisco 1921

Cisco 1900 Series Integrated Services Routers (ISR) are designed to meet the

application demands of today's small branches and to evolve to cloud-based services.

They deliver virtualized applications and highly secure collaboration through the widest

array of WAN connectivity at high performance that offers concurrent services at up to 25

Mbps. All Cisco 1900 Series Integrated Services Routers (ISR) have modular design that

allows for reuse of a broad array of existing modules that meet business requirements

while maximizing investment protection.

Cisco 1900 Series ISR include:

1 2 RU and 1 RU units with up to 2 GE integrated WAN ports

2 Up to 1 Integrated Service Module (ISM)

3 Up to 11 LAN switch ports, two Enhanced High-Speed WAN Interface Card slots

4 Hardware accelerated DES, 3DES and AES for IPSec and SSL VPNs

5 Integrated 802.11a/g/n access point with 802.11i, WPA and WPA2 for security

6 16 Wireless VLANs and 15 SSIDs

7 WAN optimization through WAAS Express

8 Secure cloud access with integrated intrusion prevention, content filtering and cloud

web security
