If you enter a value that is within the valid range but not equal to one of the
values listed above, the speed will be rounded up. If an RS-232 DCE port is
directly connected to the DTE via the standard Cabletron cable, the maximum
supported speed is 64000. If longer cabling is used, the maximum speed is 19200.

N1 Polling Count

The Polling Count speciÞes the number of polling cycles that must pass between
requests for full status reports, which include the status of all PVCs conÞgured on
the physical link. At an interval speciÞed by the T1 Link Integrity Timer
(described below), the logical data terminal equipment (DTE, or user-side
equipment, typically a workstation or router) will send a status enquiry to its
attached DCE (or network-side equipment), requesting the status of the network
link. Each exchange of one enquiry and one response (or status message) deÞnes
one polling cycle. After the number of cycles speciÞed by this value, a request for
a full status report will be sent.

N2 Error Threshold

The error threshold deÞnes the number of link reliability and/or protocol errors
that can occur during the period deÞned by the N3 Monitored Events Count
(described below) before the logical DCE is declared inactive.

NOTE

If this port is conÞgured as the logical data communications equipment (DCE), status
enquiries will be initiated at its attached DTE (or user-side equipment), and the local node
will respond with status messages. You can determine which link partner is the logical
DTE and which is the logical DCE (network-side equipment) by checking the Logical
DCE

Þeld in this window (described below).
