21-180 is a synchronous 64kbps modem for codirectional clock environments that can be used to extend reach of balanced G.703 interfaces up to 2km allowing for a cost effective transmission without electromagnetic interference and signal degradation.
The modem can use the incoming clock from G.703 interface and propagate it down the fiber or use its internal clock source running at PDH accuracy. The modems automatic clock phase adjustment accommodates for any fiber round trip delay.
