AIM-VOICE-30 Providing DSP for Voice
 depicts applications that require AAL5 or AAL2 support over T1 or E1 ATM connections. This 
configuration leaves the network module slot open for existing or future needs. In this example, the 
AIM-ATM-VOICE-30 combines all of the AIM features shown in 
, including 
support of up to 30 channels of compressed voice using AAL2 (ITU I.366.1/I.363.2) and VoAAL5 with 
the support of a T1/E1 voice/WAN interface (VWIC-1MFT-T1/E1) connected to a PBX, without 
requiring a digital T1/E1 packet voice trunk network module. In addition, the AIM-ATM-VOICE-30’s 
segmentation and reassembly (SAR) coprocessor functionality provides AAL2 and AAL5 performance 
and as many as four IMA groups, enabling fractional T3/E3 bandwidth performance.
