PLACA PA-VXC-2T1/E1 = Voice
60 CANAIS DE COMPRESSÃO DE VOZ DSPs
This document discusses techniques used to verify the basic functionality of the Digital Signal Processors (DSPs) on the PA-VXA/PA-VXB/PA-VXC Voice Port Adaptors for the Cisco 7200/7300/7400/7500 router platforms. The DSPs are necessary for packet telephony technologies such as Voice over IP (VoIP), Voice over Frame-Relay (VoFR), and Voice over ATM (VoATM). The DSPs are responsible for the conversion of voice from analog to digital forms and the other way around, to set the gain and attenuation parameters, for the operation of Voice Activity Detection (VAD), and more. Proper hardware and software operation of the DSPs is necessary to ensure that calls can be established and maintained correctly. This document also includes discussion of how to identify and troubleshoot the DSPs which are used by the PA-MCX MIX-enabled Multichannel T1/E1 Port Adaptors for the Cisco 7200 router platform, when these voice-capable Port Adaptors are used for voice termination. When used for voice termination, the PA-MCX T1/E1 Port Adaptors dynamically obtain DSP resources from a PA-VXA/PA-VXB/PA-VXC Voice Port Adaptor installed on the same Cisco 7200 router.
