Analog
Thin Route DCME VCL-TRLD, is a "Thin Route" Voice
Compression Equipment which provides “Toll-Quality” , very clear and sharp,
voice telephony channels for "thin route" (low density) applications.
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.
