Basically, by utilizing a resource manager, that directs the data in and out of the various portions of the modem in an orderly manner, keeping track of which of the ports is being operated at any given point in time, a standard single port modem can be reconfigured, for example, at an over clocked rate, to manipulate the data input and output of a modem.
What is claimed is: 1. A multicarrier multiport modem comprising a plurality of ports and one or more resource managers that are capable of configuring the ports to support a plurality of modes of operation, wherein a first mode of operation supports one port of multicarrier access communications operating concurrently with at least one first port of multicarrier LAN (Local Area Network) communications, and a second mode of operation supports the one port of multicarrier access communications operating concurrently with one or more second ports of multicarrier LAN communications, wherein the at least one first port of multicarrier LAN communications differs from at least one of the one or more second ports of multicarrier LAN communications.

No. 7,738,542, which is a Divisional of U.S. application Ser. No. 09/862,492, filed May 23, 2001, which claims the benefit of and priority under 35 U.S.C. �119(e) to U.S. Patent Application Ser. No. 60/206,502, filed May 23, 2000, entitled �Multimode Multicarrier Modem Architecture,� each of which are incorporated herein by reference in their entirety.
SUMMARY OF THE INVENTION The demand for even faster data access speeds is being driven by the desire of consumers to enhance access to the Internet and services available over the Internet, such as high-bandwidth multimedia presentations, streaming video, audio, streaming audio, and the like. This increased demand in turn creates a demand for systems and technologies that are capable of operating at these increased bandwidth's. Communication systems that enable high speed data access are being developed for both wireline and wireless systems. Typically, these systems combine a highly sophisticated signal processing technique that enables multiple bits per second per hertz of bandwidth in conjunction with an operational range over wider and wider bandwidths.
DETAILED DESCRIPTION OF THE INVENTION For ease of illustration, the functions of an exemplary DSL modem have been partitioned into sections, where each section is dedicated to perform at a certain function. However, it is to be appreciated, that this division is simply for ease of illustration, and that the functional components of the modem can be regrouped or re-associated in any way as deemed appropriate. For the exemplary embodiments of this invention, the DSL modem will be broken into four functional components. First, the ATM over ADSL interface block implements the ATM transmission conversions layer as defined in the ITU 1.432 standard. This interface block provides the connectivity from the ATM-Forum UTOPIA-Level II interfaces to a full duplex synchronous serial port that is typical on ADSL devices. Secondly, the framer block, which includes, for example, a framer, a coder, and interleaver blocks, implements the bit oriented functions of T1.143 and G.lite standards, such as, framing, a Cyclic Redundancy Check (CRC), scrambling, Reed-Solomon coding, and interleaving. Third, the transformation block implements the multitone QAM and trellis constellation encoding and/or decoding, Fourier transforms, and frequency-domain equalization algorithms that enable transmission and reception according to the requirements of the Full Rate and G.lite standards. Fourth, the equalization block implements the digital filtering portions of the front-end processing required in an ADSL modem. The filters perform plain old telephone system (POTS) protection, transmit mask application, interpolation, decimation, echo cancellation and time domain equalization (TDQ). Furthermore, each of these blocks is capable of supporting both transmit and receive functions simultaneously. The transmit functions implemented in these blocks are detailed in the G.992.1 and G.992.2 standards, incorporated herein by reference in their entirety. The receive functions detailed above are just a typical example of an ADSL receiver. It is to appreciated that other receiver structures are possible and that the receiver structure is not limited to that described herein.
For the exemplary 8-port example, and with reference to FIG. 10, the functional logic, which is directionally related to the numbers of gates, are required to support 8 ports of 8 Mbps ADSL is essentially equivalent to that required for one port of 64 Mbps VDSL. The number of FFT �butterfly� operations for one 8 MHz VDSL with a 4096 point FFT is only slightly larger than the number of butterflies required for 8 ports of ADSL, each utilizing 1 MHz of bandwidth. Thus, the same computational resources and the even the same memory buffers can be re-used with different addressing and logic control as managed and identified by the resource manager.
