Eicon Networks 1530 - Manual (Page 91)

Web Interface Settings Glossary 91
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.
