voice network modules

Bundle of AIM-ATM and VWIC2-1MFT-T1/E1 Voice/Fax and ATM AIM Modules for the Cisco 2600,
2600XM, 2691, 3660 and Cisco 3700 Series Modular Multiservice Access Routers

The Cisco 2600 Series, Cisco 2600XM Series, Cisco 2691, Cisco 3660, and Cisco 3700 Series multiservice access routers provide enterprises and service providers a wide range of solutions for data, voice, and video. These routers are equipped with an Advanced Integration Module (AIM) slot, which provides customers the flexibility to deploy additional features.

Three AIMs are described in this data sheet: an ATM AIM called AIM-ATM, a Voice AIM called AIM-VOICE-30, and a Voice + ATM AIM called AIM-ATM-VOICE-30. 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 or 16 high-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.

The AIM-ATM optimizes the Cisco 2600, 2600XM, 2691, 3660, and Cisco 3700 Series modular multiservice routers by offering ATM adaptation layer 2 (AAL2) and ATM adaptation layer 5 (AAL5) support for low-density T1/E1 data and voice connections over ATM networks. 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 or 16 high-complexity voice channels when used with the Voice/WAN (VWIC-MFT) interface card. All DSP voice features such as voice activity detection, echo cancellation, and a full suite of PBX/PSTN signaling protocols are supported. When the AIM-VOICE-30 is used in a Cisco 2600, 2600XM, 2691, 3660, or Cisco 3700 Series Router, users can use voice over IP (VoIP) or voice over Frame Relay (VoFR) while freeing up the network module slot for other applications. When used with one of the various ATM network modules, voice over ATM (VoATM) and VoIP over ATM are supported.

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 Cisco 2600 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.

These three 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. These AIM modules take advantage of the internal AIM slot(s) of the Cisco 2600, 2600XM, 2691, 3660, and 3700 series routers, ensuring that external slots remain available for components such as WAN interface network modules, and serial WAN network modules.
