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 was a general purpose, digital telephony switch designed to be controlled by a host computer. The XDS series of boards, the third generation, draws upon this experience to bring the same level of switching capability into PC environments. XDS boards have found wide usage with Computer Telephony developers.
From its beginning, AMTELCO has focused on the interface to the public telephone network, the ultimate connection of any telephony system. Drawing on years of experience in dealing with a wide variety of equipment and telephone networks, the XDS boards are designed to allow the user to take fullest advantage of the various interfaces, while insulating them from the details of network operation with field proven firmware. These interfaces are designed to be robust in nature with ample protection and full FCC certification, where applicable.
The XDS boards are committed to the concept of open architecture. Interfaces exist to connect the XDS boards to various TDM interconnect buses, both public and proprietary, allowing the XDS boards to work with other telephony boards from multiple vendors. The latest line of XDS telephony boards supports the H.100 and H.110 switching architectures, as developed by the Enterprise Computer Telephony Forum (ECTF®). The backwards compatibility of the H.100 / H.110 bus architectures, coupled with the flexible hardware compatibility of the XDS boards, had first allowed for implementation of these XDS boards into legacy MVIP™ and SCSA® environments. As new bus structures have emerged, AMTELCO has continued to be among the first to provide support for them, while also supporting audio switching through the digital backplane for more current IP-based environments such as Asterisk®. The XDS product lines include boards for PCI, CompactPCI, and PCI Express platforms.
AMTELCO XDS now maintains its forward growth into partnerships with system developers and telephony equipment manufacturers that utilize an increasing array of communication technologies. XDS Radio Interface boards are finding frequent use within modern Asterisk PBX and call dispatch systems, while ISDN line interfaces (both to the public network and to local terminal devices) continue to be an affordable and cost-effective medium. Custom board design has long been an additional offering of the XDS design team, benefiting from an experienced staff of on-site hardware engineers, firmware engineers, CAD engineers, and Production technicians.
AMTELCO XDS looks forward to maintaining a long tradition of designing and manufacturing the high quality, cost effective, reliable telephony interface products that our customers depend upon, while remaining on the leading edge of today’s changing communication technologies.
