РСМ64/M converter is used to convert G.703 64 kbps interface signals into synchronous DTE digital interfaces. 
The converter can be employed to build a duplex data link using digital trunking equipment. 
It allows to connect PCs, routers, terminals, etc. to digital trunking equipment with 
co-directional 64 kbps interface (G.703.1). 
Model РСМ64/M is stand-alone (in the metal case of type Mini).Devices DC powered 36 to 72 VDC. Possible AC Power Source 176 to 264 VAC from external 
Power adapter Cronyx AC-DC-48)
 
Built-in sync/async converter provides connection of various devices to asynchronous ports. 
Integrated BER tester and remote loopback capabilities allow to test the whole link from a local unit. 
The capability of enabling external receive and transmit clocks allows to select one of the two 
DTE emulation modes when you connect the converter to DCE. 
PCM64/M converter provides double line rate (128 kbps).
