21-170 is a converter between G.703/704 2Mbps and proprietary 64kbps fiber optical interface. It can be connected to other fiber optical converters from Fibersystem i.e. 21-16xx (for X.21, RS.530, etc). or the 21-180 for balanced G.703.
It adapts the data rate to incoming E1 signal by a digital PLL or in a back to back configuration it can be set to use its internal reference.
