Restriction (continued)
Figure 5-3. Restricted Bands.
905.500 was entered as the “start” and “end” of Band 1; this will restrict the
frequency of 905.500 MHz. The range of 909.250 to 912.700 MHz was defined
as the second (Band 2) restriction. When prompted to enter Band 3, the [Esc] key
was entered to escape the entry process and the summary at left/bottom was
displayed. Pressing [Esc] again saves and exits the process. To modify an existing
restriction, simply overwrite it. To remove a restriction, overwrite it with 000.000.
&H1
Repeater Registration
When more than one Repeater exists in a network, the Unit Address of each
Repeater should be registered within every modem in the network. The reason for
doing this is to enable the modems to create hopping patterns that are orthogonal
to each other, thereby minimizing possible interference between network
segments.
Upon entering the AT&H1 command, the modem prompts as follows:
• A to add a Repeater (this is done by entering the Unit Address of the Repeater).
• R to remove a Repeater.
• C to clear all registered Repeaters.
Press the [Esc] key to save and exit the process.
