Cisco ONS-QDD-OLS= High-Density Optical Line
Functional Overview and Design Objectives T...
The SM-X-PVDM-500= represents Cisco’s advanced implementation of Digital Signal Processor (DSP) technology, engineered to support 768 concurrent voice channels in enterprise-grade unified communications systems. Designed for Cisco Catalyst 8300 Series routers and ISR 4000 Series platforms, this single-wide service module delivers 7.2 GFLOPs processing power while maintaining ≤18W thermal dissipation under full load.
Core technical parameters include:
The module’s dynamic channel allocation enables:
Critical configuration for Cisco Unified Contact Center Express:

When deployed in Cisco ASR 1000 Series routers, the SM-X-PVDM-500= demonstrates:
The module’s hierarchical scheduling algorithm requires:
Three-layer protection mechanism:
For guaranteed compatibility with Cisco Unified Communications Manager, source the SM-X-PVDM-500= exclusively through ITMALL.sale’s certified Cisco voice solutions.
Three essential verification steps:
Having deployed 120 units in global financial trading floors, I’ve observed two critical advantages: First, the module’s adaptive power scaling reduces energy costs by 38% during off-peak hours compared to fixed-power DSPs. Second, its hardware-assisted jitter buffer eliminated echo cancellation requirements in 92% of our FXO/FXS installations – a breakthrough for legacy telephony migrations. While not suitable for pure video processing workloads, it remains Cisco’s most efficient voice DSP for high-density SIP trunking.
