Abstract

A method for using a wireless digital base station to receive, process and transmit a plurality of communications having independent data rates establishing a first communication channel having a first data communication rate to support a first communication; determining the data rate required to support the first communication; selecting one or more transmission channels, from a plurality of available transmission channels, required to support said required data rate; and transmitting the first communication using one or more selected transmission channels. The plurality of available transmission channels includes at least one B or D channel.

Claims

1. A method for supporting a plurality of communication rates with a base station that uses a plurality of communication channels comprising:

processing a first communication for transmission;

continually determining the data rate required to support said first communication;

allocating, responsive to said determining step, a sufficient number of communication channels for transmission at said data rate whereby;

a re-allocation of communication channels is performed should said required data rate change.

2. The method of claim 1 wherein said allocating step allocates D channels at a first data rate and B channels at a second data rate, which is greater than said first data rate.
