Abstract
Digital data is transported bidirectionally between a broadband network unit and devices. The data is transmitted in a series of frame intervals that include request slots and cell slots for transmission of ATM data. The request slots may be used by a device to request one or more cell slots. The broadband network unit determines which requests to grant. If the request is granted, the device may use the cell slot to transmit ATM data. In addition, the request slot can accommodate Time Division Multiplex data such as digital telephony.
