XDS H.100 PCIe 2/4-Wire E&M Board

Product Part Number: 259L030

PC Form Factor: Full-length PCIe
TDM Bus Type: H.100

Bus Capacities:

H.100 - 4096 timeslots
Analog Ports - 8

The E&M line interface board contains eight ports, each capable of 2-wire or 4-wire operation, using type I or type V signaling protocols. Signalling protocols and port types are programmed on a per-port basis. Individual ports may also be programmed for Radio Interface operation, allowing independent control of the E&M signalling leads on the application level. On-board DSP resources include DTMF detection and generation, as well as energy detection, North American / European call progress tones, and a 1004Hz calibration tone. Thirty-two independent bi-directional voice resource channels are also included.
