1.5 E911 SUPPORT
The DART type determines the maximum number of links, where there can be up to
8 DARTs for a 35MHz spectrum and up to 4 DARTs for a <
75MHz spectrum.
E911 support may be achieved by using a configuration similar to the one shown in
Figure 1-8. Remote simulcasting in this configuration requires analog splitting and
combining to and from the individual Host DARTs. External analog
splitting/combining ensures that the E911 system receives uplink signals from each
Remote location before they are combined with uplink signals from the other
Remotes in the simulcast.
