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

, 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
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."
