Product Part Number:
266L007 (PCI Modular Line Interface Baseboard)
267L006 (PCIe Modular Line Interface Baseboard)
266L011 (4-Port FXO Line Interface Module)
266L009 (4-Port FXS Line Interface Module)
PC Form Factor: 2U, full-length PCI / PCIe
Analog Ports: 4 to 16, per module population
The PCI / PCI Express Host Media Processing (HMP) Modular Line Interface board is designed to provide up to sixteen FXO or FXS line interface ports for use in PC-based telephony systems running Asterisk® software. Optional plug-on modules are available to provide either four FXO or four FXS line interfaces each. The modular base board is designed to accommodate between one to four modules, resulting in a mixture of between four to sixteen FXO or FXS ports of the user's choice. Each line interface port provides audio transmission and control support for basic line functions including hook status and ring generation and detection. Echo cancellation is supported on all active ports. Each port can be programmed to conform to common national standards and practices. A software device driver and channel driver are available for use with Asterisk 1.8 and 11, 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.
