Mr. Drummond — The rationale behind our request to standardize the Nokia microwave is <br />because the county is moving forward with MPLS equipment for the county's network. Civil <br />Defense's goal is to combine the fiber network with the microwave network so that they can <br />each act as a backup in case one fails and it can be switched over to the other system. The danger <br />in that is if we go with a different manufacturer other than our MPLS system, would be the <br />compatibility between the two systems. <br />Mr. Drummond - If we stick with Nokia microwave, one monitoring system can monitor the <br />entire network including microwave and fiber. It makes a seamless operation and we're not <br />trying to get two different vendor or manufacturer's equipment to work together. <br />Mr. Nagata — What does MPLS stand for? <br />Mr. Drummond — Multiple Protocol Label Switching. <br />Ms. Sako — It's the switches that talk to each other so that our network can run and our radio <br />system connects in as well. <br />Mr. Drummond — It will allow the radio system to use the fiber network as back up in case we <br />have a microwave link go down. It allows IT to utilize the microwave system is case we have a <br />fiber outage. <br />Mr. Drummond — MPLS is a protocol that when the data leaves its source, it's divided into <br />packets; rather than following one path to get to its destination, it will look at all the paths and <br />get there as fast as possible using multiple paths. It's an automatic patch. In the old days you <br />would have to take the patch cable and physically plug in to change routes. <br />Ms. Sako — Plus, the microwave equipment is nearing end of life so this is a prime opportunity <br />and good time to standardize these. <br />Mr. Hunt — As mentioned before, Civil Defense is not using the 800 MHz because the distance <br />and coverage just doesn't make sense for us? <br />Mr. Drummond — The 800 MHz works well in urban areas where you're trying to get building <br />penetration especially when you're dealing with high rise buildings. For rural type of setting <br />where you're not dealing with large buildings, you're dealing with a lot of foliage the VHF <br />(Very High Frequency) provides better penetration through the foliage and will also tend to <br />follow the curvature here so you'll get better coverage. <br />Mr. Hunt — and our all our Emergency Responders are carrying,P25 radios? <br />Ms. Sako — Yes. <br />Mr. Drummond — We have approx. 2,900 radios out there. All the portables, all the mobiles, and <br />mountain top equipment's have all been changed. <br />Ms. Sako — Any questions? None. <br />The Committee voted and motion was carried. <br />
