CENIC Completes Major Network Projects to Improve K-12 Networking

CENIC is pleased to announce the completion of several large ongoing projects to better serve the K12 node sites, the connection points to the CalREN backbone, and ultimately the entire K12 community. These are summarized below.

Customer Premises Equipment (CPE) Refresh Project
         K12's CPE refresh effort has been completed, and all original Cisco 7500 series routers have now been retired and replaced with newer and faster Cisco 7200 series routers.

UPS Battery Replacement Project

CENIC has just ordered the last of the needed replacement battery packs for the UPS units that protect K12 node site routers in case of power outages.

Circuit Upgrades
To better meet the increasing demands for bandwith, the K-12 High Speed Network requested that CENIC upgrade 21 circuits to Gigabit speeds. Of these 21 Gigabit circuit upgrades, all 21 have now been put into production on the CalREN-DC network. The final two Gigabit circuit upgrades, as marked, were completed before the end of February. CENIC and K12 have already identified and prioritized the next groups of circuit upgrades.
