System Description
South Sound 911, or the Combined Communications Network : Single Countywide Communications System Network (CCN:SCWCS), is comprised of the following elements:
A 21 site microwave network.
A P25 Phase 2 TDMA 700MHz Motorola trunked radio system with 21 sites, 38 channels and 74 talk paths.
A 3 site simulcast VHF network (FCC Call Sign WQVI727) that specifically covers the State Route 410 corridor from Enumclaw to Cayuse Pass with 3 repeater channels and 1 simplex channel for fire/EMS, law enforcement, and inter-agency mutual aid communications.
An UHF data network supporting Pierce Transit Operations through their TRAX system with coverage in Thurston, Pierce, King and Snohomish Counties.
A county-wide 11 site simulcast "VHF Overlay" network (FCC Call Signs WQWR930 & WQXQ550) designed to provide paging, station alerting, and mutual aid communication with outside agency first responders.
In partnership with the US Geological Survey, a Next Generation Integrated Lahar Warning System providing monitoring and detection of impending lahars, initiation of the Lahar Warning System Alert and Warning, and remote delivery of volcano information to researchers.
A final element slated for implementation in 2018 is a Distributed Antennae System (DAS) in the Pierce County Jail improving in-building voice and data coverage. DAS-like coverage will also be located in other county offices as the need arises.
