Interface converter PCM64/M
 |
Features:
|
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).
