Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs
Each SPA-DSP comprises of seven SP2603 DSP chips having a total of 21 DSP cores (three DSP cores
per SP2603). Based on the complexity of codec (low, medium, high), the density or maximum number
of channels supported per DSP core and maximum channels supported per SPA-DSP are defined.
