Interface converter PCM64/M

Specifications
Documentation

PCM64 Features:
  • G.703.1 64 kbps line interface
  • Maximum line attenuation - 10 dB
  • Full duplex mode
  • Data rate doubling capabilities
  • Digital interface V.35/RS-530/RS-449/RS-232/X.21 or Ethernet
  • Two DTE emulation modes
  • Digital, local, and remote loopbacks
  • Integrated BER tester
  • Alarm interface ("dry" relay contacts)
  • 48/60 VDC power
  • Declaration of compliance D-MDPD-7908

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).
