IDUReplacement
Therearetwosituations,whichmustbetreateddifferently.
Situation1:
ToreplaceeitheroftheIDUsatSite1.4ortheIDUatSite2.2,nothingspecialisrequired.
SimplydisconnecttheIDUtobereplaced–andreplaceitwithanewone.Replacinga
secondarylinkIDUobviouslyhasnoeffectontheTDMservice.DisconnectingtheSite1.4
primaryIDUactivatesHotStandby.AftertheSite1.4primaryIDUisreplaced,theLinkwi ll
detectthechangeandswitchbacktotheprimarylink.
IfyoureplacedtheSite2.2IDU,remembertoreconnecttheMHScable.
Situation2:
ReplacingtheSite1.2IDUisdifferent,andrequiresseveralsteps.
