Thin Route DCME
Technical Specifications
|
VCL-TRLD™ is a "Thin
Route" Voice Compression Equipment provides "Toll-Quality" voice telephony
channels for "thin route" (low density) applications. Applications include
scalable call centers, telcos, voice over point-to-point satellite data links, dedicated
data channels, rural, oil & mining IP networks and more. The VCL-TRLD™ is
available in two versions. The equipment uses advanced DSP based
Viterbi decoders with automatic Voice / Silence detection (VAD) and adaptive comfort noise
(CNG) generation to provide toll-quality voice channels. |
