TW7201I-MS
(14) CALL LIM
For limiting the number of attempts made on each
channel when trying to establish an ALE link
(00 to 99).
(15) SLF TMOUT
For setting the length of time this (self) transceiver
remains linked after the transmission of all outgoing
messages (000 to 600 in 15-second intervals).
(16) OTR TMOUT
For setting the length of time the other radio remains
linked when there are no incoming responses (000 to
600 in 15-second intervals).
(17) AUTO FILL
For enabling the transceiver to automatically add the
address of any station ALE hears to the list of approved
other addresses
.
Enter
1
for
OFF
and
2
for
ON
, or use
the arrows to toggle between
OFF
and
ON
.
(18) LQA EXCNG
For requesting that a calling or called station exchange
a measurement of the link quality received on the other
end. Enter
1
for
OFF
(no request) or
2
for
ON
(yes
request), or use the arrows to toggle between
OFF
and
ON
.
(19) LQA DECAY
For entering the time period in which an LQA memory
cell linearly decays from a state of perfect (30) to a
state of dead (0). Selectable in periods of 0, 1, 2, 4, or 8
hours.
(20) BER THRSD
For entering the acceptable bit error rate threshold
(00 to 48) for received ALE words. A threshold of 00
allows for no errors; a threshold of 48 is the maximum
amount of allowable errors. The default is 48 allowable
errors.
(21) GOLAY THD
For controlling the error correcting capability threshold
(0 to 4). A value of 0 allows for no corrections while a
value of 4 is the maximum amount of corrections
allowable. The default is three allowable errors.
(22) ERR THRSD
For
controlling the number of errors allowed before a
word is rejected (0 to 4). A value of 0 allows for no
errors while a value of 4 is the maximum amount of
errors allowable. The default is three allowable errors.
(23) MESSG OUT
For assigning a number to an outgoing message (from 0
to 9). Enter a new assigned number or an existing
number to review or change. To enter a new or different
message, use
(24) NEW MESSG
.
