Data Sheet
Voice/Fax and ATM AIM Modules for the Cisco 2600,
2600XM, 2691, 3660 and Cisco 3700 Series Modular Multiservice Access RoutersThe 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.
The Advanced Integrated Module Architecture
For better versatility, integration, and performance capabilities, all Cisco 2600, 2600XM, 2691, 3660, and 3700 Series modular access routers support internal AIM slots. The slot connects to both the main system bus and a secondary TDM bus running between the WAN interface card slots and network module slot. This flexible architecture enables the AIM to offload one or more processor-intensive tasks from the router's CPU. By supporting CPU-intensive applications such as ATM or voice services on a dedicated coprocessor, users can obtain significantly higher throughput rates and enable new services and applications. The Cisco 2600 and 2600XM Series routers have one AIM slot and the Cisco 2691, 3660 and 3700 Series have two AIM slots.

Applications
Scenario 1—Providing ATM Services
Figure 2 represents a method of providing ATM services on the Cisco 2600, 2600XM, 2691, 3660, or 3700 Series routers. Without the use of the AIM-ATM module, providing ATM services on these routers requires a unique ATM network module (NM). The AIM-ATM, when used with a Voice/WAN interface card (VWIC-MFT), can provide low-density ATM service without the use of a network module, thus freeing the valuable network module slot for other applications. A single AIM-ATM module can support up to 4 T1 or E1 lines of ATM services (two VWIC-MFT cards required) and the VWIC-MFT interface cards can connect to any ATM service provider network. Because the 2691, 3660, and 3700 Series can accommodate two AIM cards, when two AIM-ATM modules are installed, up to eight T1 or E1 of ATM services can be supported.

Scenario 2—Providing Voice Services
Figure 3 represents an AIM-based approach for providing voice services on the Cisco 2600, 2600XM, 2691, 3660, or 3700 Series routers. Before the introduction of the AIM-VOICE-30, providing digital voice service required the NM-HDV and analog voice services required the NM-1V/2V or NM-HDA. The AIM-VOICE-30, when used with a Voice/WAN interface card (VWIC-MFT), can provide digital voice service without using the NM-HDV, thus freeing the valuable network module slot for other applications. A single AIM-VOICE-30 module supports up to 30 voice channels and the VWIC-MFT interface card connects to the PSTN or PBX. Because the 2691, 3660, and 3700 Series routers can accommodate two AIM cards, when two AIM-VOICE-30 modules are installed, up to 60 voice channels can be supported.

Scenario 3—Providing ATM and Voice Services
Figure 4 shows another way of providing digital voice services as well as ATM (AAL5) services into an ATM network on the Cisco 2600, 2600XM, 2691, 3660, or 3700 Series routers. Using the AIM-ATM-VOICE-30, digital voice service and low-density ATM services can be provided without network modules, thus releasing the NM slots for other services.
With one AIM-ATM-VOICE-30 module and a corresponding number of VWIC-MFT cards installed, the Cisco Router can handle up to 30 channels of voice services and have up to three T1 or E1's of low-density ATM services. One of the VWIC-MFT ports assigned to voice services can interface to either the PSTN or PBX while the rest of the VWIC-MFT ports assigned to ATM data services can interface to an ATM network.
With two AIM-ATM-VOICE-30 modules and a corresponding number of VWIC-MFT cards installed, the Cisco 2691, 3660, or 3700 series router can handle up to 60 channels of voice services, and have up to six or seven T1 or E1's of low-density ATM services. One or two of the VWIC-MFT ports assigned to voice services can interface to either the PSTN or PBX while the rest of the VWIC-MFT ports assigned to ATM data services can interface to an ATM network.

Scenario 4—Providing FR/HDLC/PPP encapsulation and Voice on the same T1/E1
Figure 5 shows another useful application of the AIM-ATM-VOICE-30 module. This AIM can support Frame Relay (FR), high-level data link control (HDLC), and Point-to-Point Protocol (PPP). Also, FR/HDLC/PPP encapsulation and channelized voice are supported on the same T1/E1. This is especially useful for reducing the recurring cost of PSTN access and serial WAN data access for low end systems. A combination of DS0, PRI, and channel groups can be configured on the same T1/E1 interface (or across two ports of the same VWIC).
