A novel backplane routing and configuration () supports a full mesh architecture. In this novel configuration, a circuit pack determines which backplane signals to use for a transmission based on the relative distance across the backplane between the board sending the communication and the board receiving the communication. Boards sending the same relative distance use the same rows of signals (). That is, each row associated with the meshed interconnection is assigned a relative shift or distance for a connection. The rows () that represent a greater relative distance for shift between boards are intermixed next to rows () that have a relatively short distance between shifts or boards. In this manner, the number of layers required is minimized and the utilization of routing channels is optimized. In particular, for a N slot backplane with one routing channel between rows, (N/2+1) layers are required, rather than N layers. And, vertical routing is not required.

DSLAMs and associated methods of installing DSLAMs are disclosed where the components of a DSLAM are distributed in a DSL network. A distributed DSLAM as provided herein includes digital signal processing components implemented in a centralized system (e.g., a central office) on the DSL network. The distributed DSLAM also includes digital/analog conversion components (e.g., analog front end (AFE) components) implemented in a distributed node on the DSL network that is remote from the centralized system. The distributed DSLAM also includes a spanned communication link (e.g., optical fiber) between the digital signal processing components and the digital/analog conversion components. The digital signal processing components in the centralized system are considered more likely to be upgraded than the digital/analog conversion components in the distributed node. Thus, upgrades for the DSLAM can frequently be performed at the centralized system instead of at the distributed node.

A method and apparatus for encoding and decoding m-bit groups of digital data, where m is at least eight, into serial n bit groups such that each encoded serial n-bit group has sufficient data transitions therein to maintain the synchronization of a phase locked loop clock recovery circuit in a high speed serial link of a communication path. Further, this method and apparatus provides a duty cycle that is within an operational range of the ideal 50 percent, which reduces voltage drift of a. c. coupled high speed serial data links, or reduces thermal drift of optically coupled high speed serial data links.
