ACC X.25 Protocol User's Guide

Chapter 1 13

Overview

Supported Devices

Any device (or public or private packet switching network) which

conforms to t he ITU-T recommendation X.25 (or a subset thereof) should

be supportable by this ACC X.25 implementation. However, the X.25

recommendationleaves 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 f unctionalit y.

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 o f 2.2M b/s per ca rd on the 2 Channel ACC

card (Z735 0A)

The other ACC cards support E1/T1 data rates.
