Application ATecoM has developed different types of physical interfaces modules for the Falcon system. The modules fit on both the NIM- and the TIM-Card and are interchangeable. Due to the modular approach migration between different physical networks and network technologies has become easy and cost effective. Supporting rates up to 622Mbps enables you to switch to higher network bandwidth when needed. All interface modules are compliant to the related ITU-T and ANSI standards and support all relevant modes guaranteeing smooth adaptation to connected network equipment. To facilitate trouble shooting four LEDs indicate the presence of a valid carrier signal, the line status, as well as the traffic from and to the line interface. The E3/DS3 PDH module supports both, G.703 E3 and DS3 on a single module. The operation mode is selected by software. Optical interfaces are available for distances from 2km up to 80km. You can choose between duplex transceivers for use on a fiber pair, and BiDi-Interfaces interfacing to a single fiber, while still supporting for bi-directional traffic using different wavelength for TX and RX direction. A primary rate clock recovered from the network clock is provided by all interfaces. Also the interfaces can be synchronized to an external primary rate clock.
