E911 Support
The DART type determines the maximum number of links, where there can be up
up to 8 Classic DARTs or Single SuperDARTs that support 35MHz each, or up to 4
Dual SuperDARTs that support up to 75MHz each.
E911 support may be achieved by using a configuration similar to the one shown
in
Figure 14. 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.
Figure 14. 8:1 Analog Simulcast U-TDoA E911 Support Diagram
NOTE: When external E911 equipment is required, simulcasting must be accomplished via
external RF splitting and combining. The DARTs will then be in a point-to-point
configuration, as opposed to point-to-multipoint.
