Abstract

The present invention discloses a variable rate transmission system wherein a packet of variable rate data generated by a variable rate data source (20) is modulated on traffic channel by traffic channel modulator (30) if the capacity of said traffic channel is greater than or equal to said data rate of said packet. The packet of variable rate data is modulated onto traffic channel by traffic channel modulator (30) and at least one overflow channel by traffic channel modulator (32) if the capacity of said traffic channel is less than said data rate.
The present invention further discloses a receiving system for receiving variable rate data wherein a received packet of variable rate data is received on traffic channel if the capacity of said traffic channel is greater than or equal to a data rate of said packet and wherein a packet of variable rate data is received on traffic channel and at least one overflow channel if the capacity of said traffic channel is less than said data rate.
