XDS PCI / PCIe HMP 2/4-Wire E&M Board
Product Part Number:
266L002 (PCI / without echo canceller)
266L003 (PCI / with echo canceller)
267L002 (PCIe / without echo canceller)
267L003 (PCIe / with echo canceller)
PC Form Factor: Half-length PCI / PCIe
Analog Ports: 4
The PCI / PCI Express Host Media Processing board is designed to provide up to four 2-wire or 4-wire E&M interfaces for use in PC-based telephony systems running Asterisk® software. Each port provides both audio transmission and control of basic line functions such as hook status indication and detection for Type I, Type IV, and Type V interfaces. Each port can be configured to conform to a number of national standards and practices. In addition to the basic ability to place and receive calls, the PCI / PCIe HMP E&M board supports additional advanced features such as echo cancellation, guard tone generation, and push-to-talk control that may be useful for specific applications. A software device driver and channel driver are available for use with Asterisk 1.8, operating within a Linux environment (kernel 2.6). The software driver package has been verified under a number of common Linux variants, including Debian, Ubuntu, and CentOS.
