A method and apparatus for adapting a backplane from one type of connector to another type of connector is disclosed. The method includes providing a backplane with a plurality of connectors, each connector being of a first type of connector, providing at least one extension module having a plurality of connectors, each connector being of a second type of connector, and plugging the at least one extension module into at least one of the first plurality of first type of connectors, thereby converting the first type of connectors into the second type of connectors. In a preferred embodiment, the backplane is used in a SONET communications system, and the conversion is from DS1 to DS3 connectors. The conversion allows an individual user to begin with one type of connector, and later expand as the need arises to an additional type or types of connectors.

Backplane extension apparatus and method

An extendable enclosure for circuit cards provides the capability for a customer to purchase a low cost system up-front, but still allow for growth. The extendable enclosure for circuit cards comprises a first enclosure comprising a backplane, a plurality of circuit card connectors, the backplane providing electrical connectivity among the plurality of circuit card connectors, a midplane connector mounted to the backplane, the midplane connector providing electrical connectivity to the backplane, and a backplane connector mounted to an edge of the backplane and providing electrical connectivity to the backplane and a second enclosure comprising a backplane, a plurality of circuit card connectors mounted to a face of the backplane, the backplane providing electrical connectivity among the plurality of circuit card connectors, and a backplane extension connector mounted to an edge of the backplane and providing electrical connectivity to the backplane, wherein the backplane extension connector is operable to plug into the backplane connector of the first component enclosure.
