This time, we'll finish up by looking at two entrants that offer guaranteed quality of service: InView IP and WireOne Technology's Glowpoint. Results varied with the ordering and provisioning of our circuits between WireOne and InView. After each local exchange provider brought in a line, WireOne promptly shipped a preconfigured Netopia router (Model R5300) to each office with a small page that included all of the IP addresses, subnet masks and gateway addresses. We installed the router and set up the videoconferencing endpoints and PCs in minutes. For InView, we had to complete an IP address justification form, and once the circuit was ready, we needed a separate phone line for the carrier's access to a 33.6K bit/sec modem. Using the modem, remote technicians configured a DSU/CSU once the components were delivered on site. After the IP addresses were assigned, it took nearly two days at one location to troubleshoot the deployment before it correctly mapped in the wide-area service provider's network. A disappointment with WireOne's Glowpoint service was the lack of support for data collaboration. Because of strict filtering of all traffic on the service, users cannot establish T.120 sessions in parallel with the H.323 session. On the InView service, there were no traffic restrictions, permitting establishment of a parallel NetMeeting or Web conferencing session. For the guaranteed network services, a gateway can be introduced when a participant is using ISDN. (H.320-based devices use ISDN; H.323 is the IP-based videoconferencing standard.) We liked that WireOne offered a clear gateway dialing manual. We could initiate calls from the IP network through the gateway at the data rate of our choice (using a dialing prefix) to ISDN videoconferencing systems in our respective locations. In the end, we decided that we liked WireOne's Glowpoint the best. Other companies will find it difficult to match the reliability, efficiency and feature set that WireOne has developed.
