ENTRIES FOR A NET

NVOY™ TRANSCEIVER REFERENCE MANUAL
NOTE: The Response entry is only applicable to NET calls. It does not affect
a station’s ability to respond to an ANY, Group Selective or Wildcard
call.

Tune time
CAUTION: The time set for tuning antennas must be the same for all members of
the NET.
The Tune Time entry is the time that the members of the NET wait after the initial
call before sending the automatic responses to the calling station. This time should be
set to match the longest tuning time between all members in the NET.
LQA exchange
CAUTION: The exchange of LQA information during link establishment must be
the same for all members of the NET.
The LQA Exchange entry determines whether or not the exchange of LQA
information occurs during calls within the NET. If this is set to Enabled, each
transceiver adds an appropriate amount of time to the slot widths so that LQA
information can be exchanged.
Slot width
CAUTION: The slot width must be the same for all members of the NET.
The Slot Width entry determines the width of response slots for each member of the
NET.
You can set the following:
• If you want all slot widths to match the width required for the largest self address
for a member of the NET, select Fixed.
A fixed slot width extends the time taken to complete the handshake
considerably.
• If you want the transceiver to calculate the slot width required for the response
from each station, select Variable.
NOTE: Unless required for interoperability reasons, the recommended
setting is Variable.
A member station calculates exactly how long after the initial call it has to wait
before sending its response given the slot width, whether LQA information is
exchanged or not during each slot, and the tune time.
