Cisco DSP-HDA-16

The Cisco DSP-HDA-16 is a high-density analog voice and fax DSP module. It is designed to be used with Cisco voice gateway platforms, such as the Cisco 4000 Series Integrated Services Routers (ISRs) and the Cisco ASR 1000 Series Aggregation Services Routers. The DSP-HDA-16 module provides digital signal processing capabilities for voice and fax applications, allowing for the conversion of analog voice signals into digital format and vice versa. It supports up to 16 channels of voice and fax processing, enabling efficient handling of large volumes of voice traffic. This module is commonly used in enterprise and service provider networks to enable voice services, such as IP telephony, unified communications, and fax over IP. It helps to enhance the voice quality and reliability of these services by offloading the processing tasks to dedicated DSP resources.
