Internal Synchronization
Figure 4 illustrates the basic interconnectivity of a radio system using internal synchronization. In this
scenario, there are two radios collocated at one site.
Figure 4 Basic radio interconnectivity using internal synchronization
In Figure 5, there are three collocated radios. In this configuration it may be desirable to make one
radio a secondary sync source using AUTO SYNC. This provides redundancy if the primary sync
source radio (A) loses power or experiences any other failure.
Figure 5 Collocated radios, one in AUTO SYNC mode to provide redundancy
The synchronization function can be carried across links to additional collocation sites. For example,
Figure 6 illustrates a multi-link backbone with two hub sites.
Figure 6 Multiple-link site configuration, using AUTO SYNC for redundancy
Virtually any combination of hubs and repeater sites, star configurations, and/or backbones can be
implemented with synchronization using these configurations. It is typically necessary or ideal in each
configuration to match the following parameters on every radio in the network:
Note: Currently, the configuration shown in Figure 6 is not supported in all models. Consult
your Exalt representative for details.
