Well seeing how you will not have access to the ATM switch in the lab, you
must use what is being sent to you or the PVC won't work anyhow.
But to answer your question....
Hardware versus Software-Based AAL2/AAL5 Functionality on the Cisco 2600 and
2600XM
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.

Subject: Voice over AAL2
Hi group,
Voice over ATM can be configured through AAL5 and AAL2. Anyone know if AAL2
can be supported in the 2600 and 3600 platform that implies it may appear in
the exam ?
regards,
alec
