Catalyst VoIP products are low bandwidth applications. The need for
bandwidth is typically for short duration due to the PTT nature of
mobile radio, and when bandwidth is required, it frequently is less
than 30 kilobits per second. This is because most Catalyst customers
take advantage of voice compression technologies with minimal
degradation of voice quality. In addition to standard 64 kilobit per
second uncompressed digital voice (PCM), Catalyst products offer ADPCM
at 32 kilobits per second, Microsoft GSM at about 13 kilobits per
second, and Microsoft TrueSpeech ® at about 10 kilobits per second. |
