This is responsible technical analysis work with an emphasis on internetworks and telecommunications.
Nature Of Work
An employee in this class is responsible for implementing, upgrading, monitoring and troubleshooting Local Area Networks (LANs) and Wide Area Networks (WANs). Through the use of a variety of network management tools and problem isolation techniques employees monitor bandwidth use and analyze network traffic patterns and volumes on the city’s multi-site, multi-protocol network. They install, upgrade, integrate and manage the city’s WAN and LAN equipment and services including Novell and NT servers, routers, ATM switches, hubs, CSU/DSUs, gateways and other related network and mobile computing services. This work is of considerable difficulty and involves a high degree of responsibility and extensive knowledge of WAN and LAN protocols and hardware. Employees coordinate and monitor the work of other network project team members in the completion of specified assignments. Tasks require that the employees consult with user departmental personnel, other departmental technical staff, and other network team members in order to resolve technical issues. Under general supervision, employees are expected to exercise considerable initiative and independent judgment in selecting work methods and performing assigned tasks. Employees in this class are subject to on-call status on a rotating schedule to provide 7 day/24 hour per day service and, at times, are required to work unusual hours to accommodate installation, maintenance and/or upgrading of city networks. Work is reviewed while in progress and upon completion through discussions and reports submitted.
