TheDivisionofCommunicationsandTechnologyServiceshastheresponsibilityforplanning,developing,managingandmaintainingthemost
effective,efficientandeconomicalcommunicationsnetworksystem.Initsroleasasystemintegratorofnetworks,theDivisionsupportsallUniversityneedsbyapprovingandcoordinatingallvoice,dataandvideocommunicationssystemspolicies.Withtheconvergenceofvoice,data
andvideotechnologies,theDivisioniscommittedtoaseamlesscommunicationsservicesnetwork.
Inrecentyears,thefocusoncommunicationssystemplanning,operationsandprocurementforvoice,dataandvideocommunicationshave
movedincreasinglyintotheforefrontoftheattentionofUniversityadministratorsanddepartmentdirectors.Communicationssystemsarenow
seenasatoolforimprovingemployeeproductivity,facilitatingtheeducationprocessandreducingoperatingcosts.Byproviding
communicationsandapplicationscompatibilitybetweenacquiredcommunicationssystemsandrelatedservices,theUniversitywillmeetits
goalofachievingatotallyintegratedinformationsystemsenvironment.
CommunicationsandTechnologyServiceswillcontinuetomaintainasophisticatedandcomprehensivecommunicationsinfrastructurethrough
whichtheUniversitycommunitycanshareaccesstocostlytechnologyresources,andthereforeminimizeexpensiveandunnecessary
duplication.TheDivisionwilldevelopandexpandnetworksystemstoenhanceandfacilitatethegrowthoftheinfrastructurebyproviding
