Several alternatives were explored to address the challenges list above which included: e Expand the current four site single site network to six channels; replace an aging dispatch console with an IP based console and replace an out of date System Manager. e Expand the current system to a single site five channel network employing P25, replacing the console and system manager upgrading the mobile and portables to P25 and using the sixth channel for a “drop in” site to solve coverage problems. e The same configuration as noted above in the standard EDACS format which would not require upgrading the mobiles and portables. e¢ Expand the network to a two site five channel EDACS simulcast network a new IP based console and an new system manager. The proposal which follows essentially combines the best elements of the alternatives which were studied to produce a two site five channel simulcast network utilizing the legacy EDACS format and various legacy components which when added to the new IP based components produces a network which addresses the challenges noted above. A key element is the introduction of Harris RF Corp’s’ VIDA (Voice/Interoperability/Data/Access) Switch. The VIDA switch “future proofs” the network by providing a path to P25 and allows the Township via an ISSI (Inter Sub System Interface) to operate with any other P25 network (State, Regional or County). The configuration also holds in reserve one 800 MHz channel to address an area of special coverage consideration should it be required in the future. Eastern Communications’ expertise in the installation of simulcast networks assures the Township that the installation will allow a seamless transition to the upgraded network with no interruption in service.
