Link Management This parameter should be set to the link management used by the equipment
connected to it. If set to “Auto,” the unit will learn the link management type
and display it on the status portion of this screen.
Once it discovers the link management type, the unit should be set to the
discovered value so that subsequent unit or network re-initialization will be
faster.
Values: Auto, CCITT, ANSI, LMI, None
Default: ANSI
Max Frame Size If Auto Diagnostic is set to “Yes,” the unit will discard received frames that
are larger than the maximum frame size. If Auto Diagnostic is set to “No,”
these large received frames will be sent, but will be counted in the Rx Invalid
statistics.
Values: 64–4096
Default: 2500
N1 Indicates the number of “keep alive” status inquiries that are sent between full
status requests.
Values: 5–255
Default: 5 if interface is Network (UNI), 6 if interface is Serial (NI).
N2 Specifies the total number of link reliability errors and protocol errors that can
occur during the sliding event monitor count defined by N3. If this count is
exceeded, the port is declared inactive.
Values: 1–255
Default: 3
N3 Represents a Monitored Events Count. For a network, a monitored event is
the receipt of a status inquiry message or the expiration of the polling
verification timer T2. For a FRAD, a monitored event is the transmission of a
status inquiry message. This parameter defines the size of the sliding window
used by the unit to determine whether a channel or user device is active.
Values: 5–255
Default: 4
T1 Specifies the number of seconds the unit waits between issuing status inquiry
messages.
Values: 5–30
Default: 10
Tx Threshold Number of bits per second sent during a 15-minute interval after which a Tx
alarm will be triggered. Default of 0 disables this alarm.
Values: 0–4294967295
Default: 0
Tx Alarm Status of this alarm (OK, Alarmed).
