By using the possibility to bundle all 8 B-Channels a maximum data transfer rate of 512 kbit/s can be achieved. Using the D-Channel it is possible to simultaneously transfer data via Datex-P ISDN Access (X.31).

Features

  • Four independent S0 interfaces NT and TE
  • D-Channel protocol: DSS1 (1TR6 optional)
  • X.31 (X.25 via D-Channel or B-Channel)
  • All channels for simultaneous use 4 D- and 8 B-Channels
  • D64S, D64S2 (2 B-Channels)
  • Channel bundling (all B-Channels over MLPPP)
  • B-channel transmission protocol: HDLC, X.25, Frame Relay, T.70 NL, X.75, X.75 L2, PPP
