The Engineering Division is divided into six main functions that support DISN.

• Backbone Engineering: includes network modeling; backbone trunk ordering and activating; and network monitoring.

• Network Engineering: includes network changes, problem resolution, and network upgrades.

• Circuit Engineering: includes detailed circuit configuration engineering and existing circuit re-engineering. 

• Project Management: coordinates node upgrades, modifications, and new node activations.

• Resource Management: ensures accuracy of the configuration management database (DISN-W) used by the engineering section and initially screens candidate circuit requirements to determine feasibility to ride the DISN backbone.

• Quality Assurance: performs performance evaluations of DISN sites.

Hours of operation are Monday through Friday, 7:15 a.m. - 4:15 p.m. CST. For after hours emergency assistance contact DISA Global Operations Command at (618) 418-8626.
