Abstract
A communication interface with an expandable multilane cell bus that enables conversion of communication traffic received over a set of low speed or narrow band communication links according to a first communication protocol into a series of communication cells according to a second communication protocol. The cell bus enables concentration of the communication cells for transfer over a high speed communication link according to the second protocol. The communication interface includes a cell bus master that polls slave service modules while transferring communication cells to the service modules over a unidirection transmit portion of the cell bus and while receiving communication cells over a unidirection receive portion of the cell bus.
