IC-4FXS Gateway interface card for 4 analog FXS ports
The IC-4FXS is a PMC standard compatible interface card for the SmartNode 2000 series. It provides 4 ana-
log FXS ports and connects to the SmartNode base unit through a PCI packet and PCM circuit interface.
The IC-4FXS supports up to 4 simultaneous voice or fax calls. It is a flexible analog telephony card designed to
meet the needs of small enterprises that want to connect their analog telephony equipment, such as an analog
PBX or analog telephones, to a multi-service IP network.
The on-board dedicated micro-controller and DSPs off-load the CPU of the SmartNode 2000 series base unit
enabling the conversion of voice/fax circuits into related IP-packets in real-time with minimal delay and jitter.
