Abstract
A variable rate subscriber bus is adaptable to carry communications traffic in the forms of DS0, T1 or DS1 formats between a channel bank and a channel card at any one of a plurality of predetermined data rates. The data rate for the variable rate subscriber bus is selected according to the type and capacity of the channel card. The variable rate subscriber bus is capable of supporting high data rate traffic for high density channel cards while maintaining compatibility with conventional low density channel cards.
