Supported Router Platform Compatibility

1. Cisco 2600 Series Multiservice Routers (2610, 2611, 2620, 2621, 2650, 2651, 2600XM, 2691)
2. Cisco 3600 Series Multiservice Routers (3620, 3640, 3660)
3. Cisco 3700 Series Multiservice Routers (3725, 3745)

Deployment Restrictions

1. No certified hot-swap capability: Full chassis power cycle is mandatory for safe installation or replacement; live insertion/removal triggers internal bus hardware errors, active voice call audio loss and continuous IOS system error logging.
2. DSP resource dependency for voice trunking: Channelized T1/E1 digital voice services require paired VWIC-MFT multiflex trunk cards installed in router WIC/VWIC slots; the standalone AIM-VOICE-30 cannot process voice without T1/E1 trunk interfaces.
3. Shared internal chassis bus bandwidth limitation: When deployed alongside AIM-VPN/SSL crypto acceleration modules, the router’s internal AIM backplane bus bandwidth is shared between voice DSP workloads and VPN cryptographic processing; peak concurrent voice channel capacity may be slightly reduced under heavy VPN tunnel loads.
4. No integrated ATM SAR hardware: This module only provides voice/fax DSP processing; for combined ATM WAN and voice services, the AIM-ATM-VOICE-30 combined variant must be deployed instead.
5. Slot quantity limits per router chassis:
   • Cisco 2600 Series (excluding 2691): Supports only one AIM expansion slot
   • Cisco 2691, 3660, 3700 Series: Supports up to two independent AIM expansion slotsCisco

8. Universal Trunk Interface Compatibility: Works seamlessly with all Cisco VWIC multiflex trunk cards (VWIC-1MFT-T1, VWIC-2MFT-T1, VWIC-1MFT-E1, VWIC-2MFT-E1) for channelized T1/E1 digital PBX and PSTN trunk voice processing.
9. Full Native IOS Voice Feature Suite Integration: Seamless compatibility with all Cisco IOS telephony feature sets, including Cisco CallManager Express (CME), dial plans, PRI ISDN voice trunk signaling, PBX interconnection, QoS voice traffic prioritization, RSVP bandwidth reservation and voice security policies.

4. Core Deployment Advantages

1. Offboard Independent DSP Resource Design Conserves Critical Chassis Network Module Slots: The AIM-VOICE-30 leverages the router’s unused internal AIM expansion slots to host dedicated voice DSP farms, eliminating the requirement to occupy high-value external network module chassis slots with NM-HDV digital voice modules. This design frees network module bays for ATM WAN, multi-port Ethernet or other auxiliary service modules, maximizing router chassis resource utilization for multi-service enterprise branch deployments.
2. High-Density Scalable Concurrent Voice Call Capacity: A single compact internal AIM module delivers support for up to 30 medium-complexity simultaneous voice calls, enabling high-density PBX and PSTN trunk telephony deployments at remote enterprise branch offices without costly chassis upgrades or additional router hardware.
3. Dynamic Global DSP Farm Resource Pooling (dspfarm) Delivers Maximum Resource Utilization: The Cisco IOSdspfarmfeature allows the AIM-VOICE-30’s pooled DSP resources to be dynamically allocated to any T1/E1 trunk controller installed anywhere on the router chassis. Administrators avoid statically hardbinding DSP resources to individual trunk cards, eliminating wasted idle DSP capacity on underutilized voice trunks and optimizing overall telephony DSP resource efficiency across all branch trunk interfacesCisco.
4. Full Multi-Transport Converged Voice Compatibility: The AIM-VOICE-30 supports all mainstream enterprise packet voice transport technologies (VoATM AAL2/AAL5, VoIP SIP/H.323, VoFR), delivering universal flexible deployment compatibility for branch networks utilizing ATM, IP or Frame Relay WAN backhaul links for telephony traffic.
5. Complete Suite of Hardware-Accelerated Voice DSP Auxiliary Functions: All core telephony optimization tasks—voice activity detection silence suppression, comfort noise generation, long-loop echo cancellation, jitter buffer management and T.38 real-time fax relay—are processed natively on the module’s dedicated DSP hardware, removing these CPU-intensive auxiliary workloads from the router’s primary general-purpose CPU and preserving core routing, security and data service processing capacity.
6. Unified Native Compatibility with Full Cisco IOS Telephony Feature Stack: The AIM-VOICE-30 DSP resources integrate seamlessly with all Cisco IOS enterprise telephony functionality, including Cisco CallManager Express (CME), PRI ISDN trunk signaling, PBX interconnection dial plans, voice QoS prioritization, RSVP bandwidth reservation and telephony access security policies. All voice DSP resource management and telephony service configuration is centralized within a single consistent IOS command-line interface, eliminating disjointed separate management systems for data and voice infrastructure.
7. Fanless Passive Cooling High-Reliability Low-Maintenance Architecture: The AIM module utilizes a fanless passive heat sink cooling design with zero moving mechanical fan components, eliminating mechanical hardware failure risks and enabling stable 24/7 continuous unattended operation in remote unmanned branch equipment closets with minimal on-site maintenance requirements. Low idle and full-load power consumption reduces overall router chassis energy draw and enterprise branch site cooling operational energy costs.
