A module is provided for installation in a drive bay of a computer and is adapted to accommodate expansion circuitry rather than the electromechanical devices conventionally installed in drive bays. A system interface board is provided for insertion into an expansion socket on the computer's motherboard and is connected to the module, thus interfacing the expansion circuitry to the computer. The expansion circuitry can be greater in volume and is more accessible and more easily cooled than expansion circuitry installed in expansion sockets on the motherboard.

Alternate use of computer storage device bays

A distributed PBX, KSU and the like system has at least one time domain multiplexed (TDM) switch unit interfaced with transparent wideband channels such as Ethernet by means of at least one Public Switched Telephone Network (PSTN) interface unit and at least one service module (SM) interconnecting it to remote station terminals. One or more applications servers may be located where available or convenient and interact with the TDM switch unit by means of IP addressable path or paths.

The invention relates to methods and apparatus for switching a call from an unreliable network to an alternate network when a QoS of the network falls below a predetermined threshold. The invention includes a telephone call switching apparatus which monitors the QoS of the call. When the QoS of the call falls below a first threshold the switching apparatus establishes a connection over an alternate network. If after a predetermined time period or after the QoS falls below another predetermined threshold the call is transferred to the alternate network connection. While the switching apparatus is maintaining multiple network connections, the idle network connection remains muted.

Alternate network fallback for IP telephony

A cable card having increased cable connector density is provided. The cable card has a non-planar surface and, therefore, more surface area than a planar cable card having the same outside dimensions. The increased surface area of the non-planar surface permits more connectors of a given size to be located on the cable card.
