With our current software GEMS 1.17.17, AVTS 4.1.6, and our TSText files with audio; the only fast way of doing a download is via network. What would be the recommendation for the size of Network Hub, (number of ports), to use. For instance, Johnson County Kansas will have to download almost 900 AVTS units. In the state of Maryland, there are two accounts that are just under 2000 AVTS units and the other over 2000 units. We need to order the Network Hubs and cabling and get this installed and tested to meet the RFP requirements.
