"Thin Route" Voice Compression

Equipment • Provides “Toll-Quality” 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).
