X.25 Tab
This tab allows you to configure X.25 settings. Note that this tab is visible only if the protocol is set to ‘MultiLink PPP’ and if ‘Enable Always On / Dynamic ISDN (AO/DI)’ is enabled.
The X.25 tab's default parameters are suitable for most configurations, but in some cases (such as with certain X.25 long distance providers), you may need to modify them. Use the table below as a guideline.
Parameter | Description |
X.25 Version | There are two X.25 CCITT recommendations available for selection, ‘1984’ and |
| ‘1988’. This information is provided by your Service Provider and should match the |
| X.25 recommendation supported on the switch you are connecting to. |

Charging | remote system accepts reverse charging, otherwise the call may not be accepted. |

Throughput | Assigns a ‘Throughput Class’ for the virtual circuit. The Throughput Class specifies |
class | the effective throughput of the virtual circuit in bits per second (bps). Effective |
negotiation | throughput may be limited by a number of factors such as level of link utilization, |
| network congestion, and host processing. |
| Select ‘Default’ to use the Throughput Class specified in your network subscription, |
| or select one of the values between 75 and 9,600 bps. If you select a ‘bps’ value, the |
| local and remote DTEs can negotiate to use a lower value on a |
