Three combination Voice + ATM AIM modules are available on the Cisco 3700 Series. The AIM-ATM provides

asynchronous transfer mode (ATM) services to the WAN. The AIM-VOICE-30 provides digital signal

processor (DSP) services, which can support up to 30 medium-complexity voice channels. The AIM-ATM-VOICE-

30 combines the features from the AIM-ATM and AIM-VOICE-30 modules onto a single AIM module. These AIM

modules supplement the broad portfolio of Cisco voice solutions and allow enterprises and service providers the

flexibility of implementing ATM and voice solutions on the routers. These three Voice and ATM AIM modules

provide a cost-effective option for reducing recurring cost and maximizing the benefits of the advanced bandwidth

management features of the Cisco IOS software.

The AIM-ATM offers ATM adaptation layer 2 (AAL2) and ATMadaptation layer 5 (AAL5) support for low-density

T1/E1 data and voice connections over ATM networks. It supports the following ATM-IMA capabilities: up to 4

T1/E1 of IMA with a single AIM-ATM, and 8 T1/E1 of IMA with two AIM-ATM’s (maximum 4 T1/E1 IMA bundle).

This AIM module allows service providers and enterprise customers to take advantage of the reliability and quality

of service (QoS) available with ATM connectivity. The AIM-VOICE-30 contains DSPs that can support up to

30 medium-complexity voice channels when used with the Voice/WAN (VWIC-MFT) interface card. When the AIM-

VOICE-30 can be used in a Cisco 3700, for voice over IP (VoIP) or voice over Frame Relay (VoFR) connectivity while

freeing up the network module slot for other applications. The AIM-ATM-VOICE-30 combines the ATM features

of AIM-ATM and voice features of AIM-VOICE-30 in a single AIM.

The Data Encryption AIM’s available for the Cisco 3700 Series offloads encryption processing from the CPU,

providing over 10 times the performance over software-only encryption. The AIM-VPN/EP on the Cisco 3725

supports a maximum of 800 tunnels. On the Cisco 3745, the AIM-VPN/HP supports a maximum of 1,800 tunnels.

The recently released AIM-VPN/EPII and AIM-VPN/HPII further extends the encryption performance of the

Cisco 3700. These modules offers hardware accelerated DES/3DES and the new AES (Advanced Encryption

standard) encryption at speeds up to 90-Mbps on the Cisco 3745 (max based on 1400 byte packet size). In addition

the AIM-VPN/EPII and AIM-VPN/HPII support hardware-assisted layer-3 compression services where bandwidth

conservation may lower network connection costs. The AIM-VPN/EPII on the Cisco 3725 supports a maximum

of 8,000 tunnels, and the Cisco 3745, with the AIM-VPN/HPII supports a maximum of 10,000 tunnels.

KEY APPLICATIONS AND BENEFITS

The Cisco 3700 platforms are designed for the Full Service Branch office that are deploying advanced applications,

that require higher performance for voice, security, QoS, content acceleration and delivery, and high availability

at the network edge by integrating functions previously addressed by a combination of platforms.

ADVANCED SECURITY SERVICES AND VPN’S

The Security and VPN features of the Cisco 3700 offer customers the ability to deploy proven security features such

as secure VPNs, Intrusion Detection Systems (IDS), and firewalls, as well as high-speed Internet access and the ability

to create extranets or demilitarized zones (DMZs). Cisco access routers deliver a rich, integrated package of routing,

firewall, intrusion detection, and VPN functions for multiservice applications.

VPNs help companies reap benefits such as dramatically lowered WAN costs, improved global connectivity, and

better reliability, while enabling capabilities such as secure extranet communications. Remote dial, Internet, intranet,

and extranet access can all be consolidated over a single WAN connection to the Internet. The Cisco 3700 VPN

solution supports the features essential to VPNs—IPSec data encryption, tunneling, broad certificate authority

support for public key infrastructure (PKI)—and advanced features such as stateful VPN failover, certificate auto-
