The volunteers who will be running the EVRC must be trained and exercised regularly, and should have personal disaster preparedness plans.
improved version of EVRC known as EVRC-B and a wideband version of EVRC
as the EVRC and EVRC-B vocoders in consumer handsets gives network
Sarma, Scientist C, EVRC, Mumbai, participated in X International Conference on Molecular Epidemiology and Evolutionary Genetics of Infectious Diseases, at Amsterdam (November 3-5, 2010).
Other features and functions include two-way Short Messaging Service (SMS) capabilities; simple and mobile IP; AT command interface; dual UARTs; analog audio; two RF connectors; high-speed packet--and circuit-switched data; and support for both 13k QCELP and EVRC vocoders.
It integrates several components, including a 32-bit ARM RISC processor core, an OAK+DSP core, peripherals, audio codec, a CDMA/AMPS modem and QCELP-8k/13k and EVRC vocoders into a single chip.
Model CM-SB200 features enhanced variable rate codec, or EVRC. The Astra dual-band phone can switch from 1.9 GHz PCS CDMA and 800 MHz analog, allowing service for digital or analog cellular networks.
The CEVA-TeakLite-III architecture also supports a wide range of voice codecs and telephony functions, including G.7xx, narrow and wide-band AMR, EVRC, noise reduction, beam-forming, and speech recognition.
GL's VoIP products generate/analyze thousands of calls simultaneously with traffic types such as voice files, digits, tones, noise, and fax using G.711, G.729, AMR, EVRC, and GSM codecs.
Designed to enable wireless infrastructure developers to quickly add adaptive rate GSM-AMR or EVRC voice coders to their existing and next-generation networks, the transcoders use T1/E1 connections or the industry standard H.110 telecomms bus to route calls.
"The network appliance provides a modular and flexible solution to generate real voice calls using industry standard voice codecs such as G.711 A/[micro]-law, G.722, G.722.2 (AMR-WB), G.722.1, G.726, G.729A/B, GSM (EFR, FR and HR), AMR (Narrowband and Wideband), EVRC, EVRCB, EVRC-C, iLBC, Speex, SpeexWB, RFC 2833, and user-defined codecs for voice and tones."
