Amtelco XDS - Leaders in TDM Board Technology
Amtelco was founded in 1976.  Since its inception, Amtelco has been a leader in call center and telephony innovations.  These innovations led to the XDS CTI Boards Division in 1980.  The Amtelco XDS Division designs, manufactures, and markets telephony interface boards, conferencing boards, multi-chassis interconnection boards, BRI boards, and analog port boards in a variety of formats (MVIP, SCSA, H.100 PCI, and H.110 CompactPCI).

Amtelco XDS also modifies these boards for special applications.  Developers and specialized computer and telephony board manufacturers worldwide utilize XDS technology to produce state of the art solutions for central offices, call centers, wireless switching platforms, and conferencing platforms.

XDS Series of Boards
The XDS series of boards was designed to bring the switching capabilities of much larger switches to the PC platform. XDS, which stands for eXternally Defined Switching, is the third generation of switching products from Amtelco.  The first generation was a voice grade line concentrator introduced in 1977.  The second generation, the Amtelco Switching Peripheral, or ASP, was introduced in 1985.  The ASP is a general purpose, flexible switch designed to be controlled by a host computer.  It has been deployed in a wide variety of configurations with numerous PBXs, paging terminals, and voice storage equipment.  The XDS series of boards, the third generation, draws on this experience to bring the same level of switching capability to PCs.  XDS boards have found wide usage with Computer Telephony developers.
