The town of Greenwich, Conn. has upgraded its municipal network from ATM to Metro Ethernet in partnership with Optimum Lightpath, the broadband services arm of Cablevision Systems Corp.

Optimum Lightpath, which built and then managed the town’s original ATM network over the last five years, said the new network will link Greenwich’s 16 municipal government facilities, four libraries, 11 elementary schools, and three middle schools, as well as Greenwich High School. Previously, network traffic was carried between the government buildings, libraries and schools via three physically disparate networks.

“Now, the new Metro Ethernet network gives them the ability to remotely manage sites, to use quality of service protocols to separate data and voice traffic, and to totally segregate the police application traffic from the rest of the town network, as required by state law,” said Optimum Lightpath SVP of Marketing and Product Management Kevin Curran, in a statement.

On the speed front, the upgrade moves the town from a 10/100 Mbps ATM to a Metro Ethernet system capable of 1 Gbps, at a minimum, throughout the network’s 36 locations.
