• On the Cisco 2600 and 2600XM Router, up to 30 voice channels are supported. On the Cisco 2691, 3660,

and 3700 Series, up to 60 voice channels are supported using two AIM modules. The open network module slot

can be used to support additional NM for greater multifunctional support.

• Integrated WAN data access and channelized voice on the same E1/T1 are supported which reduces the recurring

cost of data WAN and PSTN access.

• The AIM-ATM-VOICE-30 significantly reduces the load on the 2600 and 2600XM Routers’ CPU

(CPU utilization) as compared to the software-based solution.

• By offloading the router CPU of the cell-processing function, the router performs at a higher level, resulting

in additional feature support.

• The AIM-ATM-VOICE-30 can support a significantly larger number of connections or voice channels when

compared to software-based solutions.

• Uses a dedicated onboard (AIM) hardware-accelerated coprocessor, capable of supporting both AAL2

(ITU I.366.1/I.363.2) and AAL5 (VoIP, proprietary VoFR-over-AAL5), offloading the main router CPU from

the processor-intensive task of ATM cell segmentation and reassembly.

• Provisioning networks over ATM by incorporating AAL2 or AAL5 encapsulation provides higher quality

of service (QoS) and a low-cost alternative to circuit-based services.

• The Cisco 2600/2600XM/2691/3660/3700 Series with the AIM-ATM enables service providers to increase

revenue by building differentiated service options based on premium, standard, or best-effort service classes.

• The AIM-VOICE-30 and AIM-ATM-VOICE-30 offer flexible, high-density digital voice over ATM AAL2

and AAL5 support for up to 30 or 60 voice calls when used with a 2-port VWIC-MFT card.

• This application provides support for both AAL2 (ITU I.366.1/I.363.2) and AAL5 (VoIP, proprietary

VoFR-over-AAL5), with up to 4 T1/E1 connections (2600, 2600XM) or up to 8 T1/E1 connections (2691, 3660,

3700 Series).

The AIM-ATM supports the following ATM services:

• Supports up to four ATM T1/E1 ports per AIM, using two 2-port multiflex T1/E1 VWICs in WIC slots,

NM-xFE2W, NM-2W, or NM-HDV

• ATM class of service (CoS) features CBR, VBR-nrt, VBR-rt, ABR, and UBR

• AAL5: H.323 VoIP, up to four T1/E1 channels of AAL5 (with IMA support)

• VoATM-AAL2 (trunked only)
