Pine Tree networks builds redundant internet access with Ethernet

Pine Tree Networks used a SONET Ring to deliver both voice and internet access, but the demand for Internet service has grown to the point where the traffic on the SONET ring was congested. The Net to Net Technologies, Inc. DSLAM sites in Pine Tree’s Central Offices were being fed by two T1 lines, but available bandwidth was shrinking quickly.

Pine Tree Networks decided to run a new Gigabit Ethernet network in parallel to their SONET ring. Ethernet proved to be a low-cost solution that provided a full 1 Gigabit (Gb) of bandwidth. By moving customers’ Internet traffic to a separate network, Pine Tree reduced the bandwidth stress on the existing SONET ring and providing a fast, dedicated data path for the Internet traffic. Pine Tree Networks chose GarrettCom’s 6K16 Managed Ethernet Switches and S-Ring Redundancy Manager software for the task. 6K16 Switches are installed in each Central Office to form a redundant the Gigabit fibre ring.
