Microhard Systems IP-921 Operating Manual page 92

IP9xx Series
6.0 Configuration
Frequency Restriction (continued)
With the IP Series having the option of, and configured for, a Link
Rate of 1.1Mbps, the Frequency Restriction input format remains
the same (as for 345kbps described previously), however, the
Channel Number must be reduced by the number of channels
restricted, i.e. If Channels 1-3 are restricted, the Channel Number is
Image 6S: Frequency Restriction, 1.1Mbps
The Frequency Restriction ‗value' must be input into EVERY
MODEM in a network. Oftentimes the applicable Unit Address (as
input in the format detailed previously) will be ‗1' - indicating that
that the Master modem - to which other units synchronize - will not
be transmitting on the specified channel(s). All units in the system
will use this information - as input into each one of them - to
generate the appropriate hopping pattern for the network.
