Caller Name is stored in a SCP. It is a TCAP transaction. The receiving switch via SS7 recieves the calling party number in the ISUP message of the SS7 datastream. It is normally in the IAM mesasge. Then a TCAP CNAME query is launched from the called switch thru the STP's to a SCP which has the calling name database. The TCAP query returns back to the launching switch the caller name. LIDB is for operator services etc. CNAME is a TCAP database lookup, much like 800 number translations.
