A communication system 100 acquires band class information and assigns a band class to MS 102 when the MS is engaged in a process of initiating a connection with infrastructure 104. The MS informs the infrastructure of the MS's band class capabilities when the MS initially performs an access attempt with the infrastructure in a reveres link associated with a first band class, that is, on r-csch 142 in reverse link 140. When the band class where the MS initially attempts access is congested, or the infrastructure desires to switch the MS to a second, alternate band class for any other reason, the infrastructure is able to immediately determine the band classes supported by the MS and to immediately assign the MS to a f-csch 132 or traffic channel 134 in a forward link 130 that is associated with the second, alternate band class supported by the MS.
