T-CSI - (Terminating - CAMEL Subscription Information)

CAMEL operation requires additional CSI (CAMEL Subscription Information) to be included as part of a mobile subscriber's subscription information in the HLR. This will be forwarded to the appropriate VLR when the mobile attaches and moves around the network. There are two types of CSI; these are O-CSI (Originating - CAMEL Subscription Information) and T-CSI (Terminating - CAMEL Subscription Information). The later phases of CAMEL include many variations of CSI.
