  Ordering Information

Valiant's 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 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.
