Eicon Networks 1530 manual Enables/disables X.32 dialout. Default Disabled

Link Setup

Defines how the HDLC Link setup procedure is handled. Applies only if a DTE port has been configured. Default: Active.

•Active: The Eicon 1530 will initiate the setup procedure. This option is generally used with DTE addressing.

•Passive: The Eicon 1530 will wait for the remote device to initiate the setup procedure.

Sequence

In 1984, the CCITT added an Extended Sequence definition to the X.25 specification. These features are useful for networks with long transmission delays, such as satellite networks. Consult your network provider to see if you can make use of Extended Sequence features. This parameter increases the range of values available for Maximum Window Size. Default: Normal.

•Normal: Sets the range for Maximum Window Size to 1-7. Use for most networks.

•Extended: Sets the range for Maximum Window Size to 1-127. Use for networks supporting the Extended Sequence definition.

GOSIP

Enables/disables support for the Government Open Systems Interconnect Profile (GOSIP) requirements for data communications products.

Default: Disabled.

X32 Dialout

Enables/disables X.32 dialout. Default: Disabled.

Maximum Retry Count (N2)

Defines the Maximum Retry Count, which is the limit to the number of retries made when a particular frame meets with repeated negative acknowledgments from the remote device.

Range: 1-99.

Default: 10.

Reject RR/RN/REJ Frames

Enables/disables rejection of RR/RNR/REJ frames that have their poll bit set to 0. Certain networks use the HDLC poll bit in a non-standard manner and require special handling of the three frame types:

•RR (receiver ready) frames

•RNR (receiver not ready) frames

•REJ (reject) frames

Normally, when any of these three frames are received as commands with the poll bit set to 0, they are rejected. Non-standard networks may not want these frames to be rejected.
