KVC.1M is a voice module transmitting high quality voice over the Kilomux link.
KVC.1M digitizes the analog voice traffic using either the PCM or ADPCM technique. When using PCM, voice is digitized at 64 kbps, A-law. When using ADPCM, voice is digitized at selectable rates of 16, 24 or 32 kbps, according to the quality desired and the available main link bandwidth. The Kilomux main link bandwidth is limited to 768 kbps when operating with KVC.1M modules.
Perfect toll quality reproduction is guaranteed when using PCM or 32 kbps ADPCM, complying with ITU G.711
and G.721, respectively. High quality voice reproduction is attained at 16 and 24 kbps, ADPCM.
