An apparatus for communicating packetized data over a communications link using a channel bank having a time division multiplexing addressing scheme, the communications link having a predetermined format for data transmitted over the communications link including a framing bit and a frame period defined by the framing bit, is provided wherein the apparatus comprises a plurality of channel units for generating packetized data, each piece of packetized data having a packet period corresponding to a sufficient amount of time to communicate the packetized data over the communications link, a system for allocating the communication link to a channel unit that is currently sending data over the communications link for the packet period, a system for skipping the framing bit when communicating said packetized data if the framing bit occurs during the packet period, a system for determining a next sender of packetized data over the communications link, the determining system being distributed over the plurality of channel units so that each channel unit independently determines whether it is the next sender, and a system for allocating the communications link to the channel unit that is the next sender of packetized data after said packet period so that the time division multiplexing addressing scheme of the channel bank is ignored, and the channel bank is communicating packetized data. A method for communicating packetized data over a channel bank is also disclosed.

System and method for communicating packetized data over a channel bank

A method for communicating packetized data over a communications link having a predetermined format including a framing using a channel bank having a time division multiplexing addressing scheme is disclosed in which a plurality of channel units may generate packetized data and the communications link may be allocated to a channel unit that is currently sending data over the communications link. The next sender of packetized data over the communications link may be determined by a system distributed over the plurality of channel units so that each channel unit independently determines whether it is the next sender. The communications link may be allocated to the channel unit that is the next sender of packetized data after the current sender of packetized data so that the time division multiplexing addressing scheme of the channel bank is ignored and the channel bank communicates packetized data. An apparatus for communicating packetized data over a channel bank is also disclosed.
