Discontinued, recommended replacement is: PCM64/M

Specifications
Documentation

PCM64 Features:
  • Maximum line attenuation - 10 dB
  • G.703.1 64 kbps line interface
  • Full duplex mode
  • Digital interface V.35/RS-530/RS-449/RS-232/X.21
  • Data rate doubling capabilities
  • Digital, local, and remote loopbacks
  • Integrated BER tester
  • Two DTE emulation modes
  • Alarm interface ("dry" relay contacts)
  • Built-in AC/DC power unit
  • Declaration of compliance D-MDPD-8905

PCM64 converter is used to convert G.703.1 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).

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 converter provides double line rate (128 kbps).
