AIM-VPN/EPprovides support fora maximum numberof 800remote access tunnels,but alsoprovides greatertriple
Data Encryption Standard (3DES) performance when compared to the AIM-VPN/BP. The AIM-VPN/EP is designed
to take advantage of the performance power of the Cisco 265x, Cisco 265xXM and Cisco 2691.
The recently released AIM-VPN/EPII further extends the encryption performance of the Cisco 2691. This Module
offers hardware accelerated DES/3DES and the new AES (Advanced Encryption standard) encryption at speeds up
to 80-Mbps performance (max based on 1400 byte packet size). In addition the AIM-VPN/EPII supports
hardware-assisted layer-3 compression services where bandwidth conservation may lower network connection costs.

The new AIM-ATM provides a high-performance hardware-based ATM access solution for one to four T1 or E1
connections supported by the T1 or E1 VWICs (for example, VWIC-IMFT-T1). This frees the network module slot
to support other functions. When used in combination with a high-density voice network module (NM-HDV-xxx),
the ATM AIM supports ATM adaptation layer (AAL) 2 and AAL5 VoATM. In addition, the new AIM-VOICE-30
and AIM-ATM-VOICE-30 AIMs provides a cost effective solution forsupporting voice services or digital voice over
ATM (AAL2 and AAL5) support, without the use of a network module (refer to Appendix C for the complete list of
supported AIM modules for the Cisco 2600 Series).
Cisco IOS Software
The Cisco 2600 Seriessupports over fifteen different Cisco IOS feature sets, from awide range of Cisco IOS features.
This includes a variety of intranet,multiprotocol, QoS,and Security applications in use today. The Cisco 2600 Series
offers four base protocol feature sets and a combination of premium feature options including the Plus, encryption
and firewall feature sets.
The base feature sets are:
•IP
• IP/IPX/AppleTalk
• Enterprise
• Enterprise SNA Switch
The Base feature sets support popular protocols and standards such as NAT, OSPF, Border Gateway Protocol (BGP),
Remote Access Dial-In User Service (RADIUS), IP Multicast, RMON, and WAN optimization features (such as
Bandwidth on Demand; Custom, Priority and Weighted Fair Queuing, Dial Back-up and RSVP).
The following Premium feature sets are offered in combination with the above base feature sets:
• Plus
• Plus with IPSec Encryption (56-bit and 168-bit with 3DES)
• Firewall
