The AIM-ATM-VOICE-30 combines the ATM features of AIM-ATM and voice features of AIM-VOICE-30 in a single AIM. In addition to these ATM and voice features, the AIM-ATM-VOICE-30 also supports FR/HDLC/PPP encapsulation and channelized voice on the same T1/E1 interface to PSTN. This feature greatly reduces the recurring cost of PSTN access and data WAN access. The AIM-ATM-VOICE-30 enables voice and data traffic to be carried over an ATM network using AAL2 and AAL5 encapsulation when installed in Cisco 2600, 2600XM, 2691, 3660, or Cisco 3700 Series router. When used with T1/E1 Voice/WAN interface cards for circuit-mode data and frame-mode data over an ATM network, the AIM-ATM-VOICE-30 supports up to four (Cisco 2600, 2600XM Series) or eight (Cisco 2691, 3660, 3700 Series) T1/E1 WAN interfaces, which can be independent links or inverse multiplexing over ATM (IMA) groups. This AIM introduces T1/E1 ATM uplink capability in a WIC slot of the Cisco2600 and 2600XM Series. For data applications, this allows for low-cost ATM WAN access. For voice applications, when used with the existing NM-HDV, NM-HDA, and NM-1V/2V voice cards in the NM slot, this configuration allows VoATM to be supported on the Cisco 2600 and 2600XM Series platforms.
