“As more and more of the work that we do depends on a connection to the internet, it becomes essential to ensure a level of network and Primary Rate Interface (PRI) redundancy. As one outage at the Lakehill Road location affects all buildings, the general solution is to provide network and PRI redundancy by taking advantage of the recently acquired Maintenance Facility at 834 Saratoga Road. The Capital Project, currently underway, can provide a conduit and fiber from BH-BL High School to the Maintenance Facility (or from the High School to the Kingsley Road exit). The general solution will be to have one network connection come out of the high school via Lakehill Road and travel south, and a second WAN connection to NERIC leaving from 834 Saratoga Road and traveling north. From a PRI perspective, the primary PRI (to be called a SIP trunk) will be located at 88 Lakehill with the second SIP trunk hosted at NERIC.”

The recommended solutions are as follows:
The recommended solutions are as follows:
- Change PRI providers from Verizon to L3 Communications, which has quoted a service that provides an automatic failover of the inbound calls to allow for minimal downtime. One PRI will come out of BH-BL High School (88 Lakehill Road) while the other will terminate at the Northeastern Regional Information Center (NERIC) Datacenter. In the event of a significant local outage, inbound calls will come in to NERIC where they can be forwarded to predetermined numbers (cell phones).
- Contract with Time Warner Cable (TWC) for the second WAN connection to NERIC. Their solution provides single carrier redundancy in that if any part of the build out goes down, TWC re-routes traffic to the other end of the network leaving single points of failure to Stevens, O’Rourke Middle School, Pashley and Charlton Heights. However, it guarantees that the BH-BL network always has a connection to NERIC and, in turn, an internet connection.
- In the immediate future provide redundancies by turning on microwave infrastructure that is still in place. The District Office is currently connected to the network via the high school with this technology. This option will provide network redundancies at 45Mbps, which will provide sufficient connectivity to support services like VOIP while allowing for some capacity for instructional activities.
- For the longer-term solution of complete redundancy, authorize NERIC to put out an RFP so that multiple carriers can bid on the project.
