Abstract: A reconfigurable interconnect/switch for selectably coupling network devices, media, and switch fabric. The reconfigurable interconnect/switch enables network devices, such as network processor units (NPUs) to selectively communicate with other NPUs, media (via a media interface), and switch fabric (via a switch fabric interface), thus providing flexibility in the use of network line cards and the like. Embodiments of the switching/routing scheme may be employed to support network devices having separate media and/or switch fabric interfaces, as well as network devices having selectable media switch fabric (MSF) interfaces that share signal lines.

Abstract: An Advanced Mezzanine Card (AMC) adapter may be used to connect a non-AMC mezzanine card to an AMC carrier. The AMC adapter may include a card edge connector configured to be connected to an AMC connector on the AMC carrier and one or more mezzanine connectors configured to be connected to the non-AMC mezzanine card. The AMC adapter may also include a bridge to convert between communication protocols used by the non-AMC mezzanine card and the AMC carrier. Of course, many alternatives, variations, and modification are possible without departing from this embodiment.

Abstract: A switching system includes a backplane having slots, each including a first set of connectors designed according to a common specification. The slots include at least one extended slot and at least two normal slots, each normal slot including the first set of connectors, each extended slot including the first set of connectors and an additional second set of connectors. The backplane has signal lines to support a data channel between first set of connectors of the normal slot and the extended slot. The backplane also has signal lines to support a data channel between first set of connectors of the normal slot and the second set of connectors of the extended slot.
