MACC 9-1-1是Grant County，WA的唯一公共安全应答点（PSAP）。2013年，MACC 9-1-1收到了63,831份紧急情况和非紧急呼叫。
Dean Hane管理MACC 9-1-1无线电通信基础设施和系统，调度控制台系统和第一个响应者用户设备：“我们位于农村农村，拥有大面积的覆盖。我们提供超过30个机构和约1,300名订阅者包括3000平方英里管辖范围的执法，火灾和紧急医疗服务。“

MACC 9-1-1 was using a VHF wideband analog system. The VHF frequency pairs were clearly inadequate, yet acquiring additional frequencies to work with neighboring counties was proving difficult.
MACC 9-1-1 began the search for a critical communications solution partner to address:
霍先生说，“我们希望一个解决方案合作伙伴，它将提供若干价值观，如专业知识，专业性和提供的能力。如此，我们想要确保我们选择的供应商将成为一个长期合作伙伴。我们考虑到这些决定点，我们选择了扦走。“
MACC 9-1-1 wanted a standards-based, digital system that was commonly accepted in the public safety industry. "We certainly didn't want a proprietary system, so we chose the P25 open standard technology. Based on the issues with our existing system, we decided a P25 trunked simulcast network with Linear Simulcast Modulation (800 MHz) would be the best platform."
MACC 9-1-1 and Tait Communications worked closely together on a complex and innovative network design. There were several hurdles that had to be addressed before installing the TaitNet P25 Trunked Simulcast Network including:
TAIT解决方案包括并行VHF窄带模拟拟模电易系统，以满足窄带截止日期，确保互操作性，并允许足够的时间从模拟到数字流动过渡。
"We did consider multi-band radios but not all vendors offer Linear Simulcast Modulation. We also found certain feature sets were limited with multi-band radios across vendors so this option was ruled out quickly."
该项目的最终阶段是交付11个网站的蒂特网P25集群Simulcast网络（800 MHz）。霍恩先生说，“我们得到了线性Simulcast调制（LSM）的”全P25膳食交易“，P25阶段1操作，可选择升级到P25.第2阶段，1,300级P25TP9100.和TM9100.AES加密RADIOS，九个AVTEC控制台Dispatch Integration那服务包括项目管理，设计，安装，调试和培训。“
MACC 9-1-1和Tait Communication之间的强大伙伴关系极大地利用了授予县的第一个响应者和公民的公共安全。霍恩先生说，“Tait是我曾在这一性质上工作过的最好的合作伙伴;我已经在这个行业超过20年，并处理了许多多百万美元，合同项目。这肯定不是供应商的关系，我们有一个真正的伙伴关系。“
Improving officer safety was a key driver for the project. Mr Hane says, "The transition from analog to digital has significantly improved our officer safety with better communications coverage and better audio quality across from the new digital system."
由Tait专家设计的公共安全系统是自然，有弹性和强大的。斯科特Quintavalle，首席技术官，达通沟通，评论，“在紧急情况或灾难中，蜂窝技术通常被过载，紧急无线电通信必须执行。我们设计了MACC 9-1-1网络以承受多重故障。”
霍先生继续，“捷站的保守设计过程已经收偿。我们现在可以处理多点网络故障，并继续在危机时期为我们的第一个响应者提供通信。由于系统一直在线，我们已经在线，我们有多个避雷风暴，雨暴，冰雹风暴和风暴等事件，我们已经采取了多次失败，我们的系统继续表现！“
跨部门事件很容易配合the new communications system according to Mr Hane. "Multi-jurisdicational coordination is much smoother. We have more advanced feature sets on our emergency communications system than we've ever had before. For example, we implemented Advanced Encryption Standard (AES) for law enforcement so they can conduct covert operations in a secure environment. We work with the Department of Justice and U.S Marshals often. With the new system, there have been instances where there have been so many bad guys apprehended and arrested that the jails in Grant County are full. Without encryption or without working collaboratively on our system there's no way that would have ever happened in the past."
Mr Hane concludes, "When I look back, Tait provided a very robust design. We now have an emergency radio communications system that has been designed around our functionality and critical communications requirements. I am very happy with Tait and what the partnership has achieved for public safety in Grant County."
