Chapter 22: The 9160 G2 As Base Station
Connectivity Options: Base Station Mode
Message Mode Limit
This parameter defines an upper limit to the number of messages that must be
queued for transmission before message mode polling starts. Accepted values range
from 0 to 7, where 0 disables message mode.
Note: The number of terminals and past events are also part of the algorithm
that determines whether or not to start message mode.
Callsign Period
A call sign is periodically transmitted as an audible Morse code signal. This
parameter specifies the interval in minutes between call sign transmissions.
Acceptable values range from 0 to 60. The federal agencies, Industry Canada and
the Federal Communications Commission in the United States, require that each
system transmit its own identification call sign every 15 minutes.
In countries where a call sign is not required, setting this parameter to 0 prevents the
transmission of any call signs, allowing for shorter poll time-outs in terminals and
faster channel switching.
Callsign String
This string can be a maximum of 10 characters long. All characters are either
numbers or letters. The prefix “DE” (from) is added to the beginning of the trans-
mitted call sign.
22.3.3.2 Radio Parameters
Sync Delay
Important: This parameter should not be changed from its factory setting
without a clear understanding of the timing of the radio protocol.
Sync Delay specifies the delay between the time of the base station transmission and
the first response window, measured in character times. The value assigned to this
