Valiant Communications VCL-TRLD "Thin Route" Voice Compression
Equipment™ is a "Thin Route" Voice Compression Equipment provides
"Toll-Quality" voice telephony channels for "thin route" (low density)
applications. The VCL-TRLD is equipped with 128ms echo cancellers. Applications include
scalable call centers, telcos, voice over point-to-point satellite data links, dedicated
data channels, rural, oil & mining IP networks and more.
Product
Overview
The VCL-TRLD™ is available in two versions.
The first version provides a Single, Toll
Quality voice channel @ 9.6Kbps for transmission over a standard RS232 (asynchronous) data
interface.
The second version provides Six, Toll
Quality voice channels on a single, 64Kbps, synchronous channel (single time-slot).
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.
The interface to the local PSTN is analog and is available
with FXO, FXS and E&M (2 wire / 4 wire) options. The VCL-TRLD is ideally suited in
"thin route" telephony applications where a limited number of voice channels are
required to connect two locations through satellite links, or through limited bandwidth
data channels.
