Any device (or public or private packet switching network) which conforms to the ITU-T recommendation X.25 (or a subset thereof) should be supportable by this ACC X.25 implementation. However, the X.25 recommendation leaves many areas open to different interpretations and implementations, and operation in any particular case may require careful selection of a compatible set of configuration parameters.

Note that this X.25 Protocol product fully supports the DTE interface. It will also support some of the features of a DCE interface, however these are intended to be used in loopback configurations and direct computer to computer connections where the other end of the connection is a DTE device. Some features normally found in the X.25 DCE interface may not be supported. Please check with your local HP support representative for more information concerning the DCE functionality.

This protocol can be used at data rates up to:

  • 76.8k b/s, simultaneously on all eight MUX ports of the HP-PB card (Z7200A)

  • 128k b/s simultaneously on all eight MUX ports of the EISA ACC interface card (Z7400A)

  • 2 Mb/s simultaneously on all eight MUX ports of the PCI ACC interface card (Z7340A)

  • an aggregate throughput of 2.2M b/s per card on the 2 Channel ACC card (Z7350A)

The other ACC cards support E1/T1 data rates.
