10 Glossary of Terms
10.1
ANI
Short for automatic number identification, a service that provides the
telephone number of an incoming call. ANI is used for a variety of functions
-- by receiving the incoming telephone number, telephone companies can
direct a call to the proper long distance carrier's equipment; it can help
identify the caller's address to speed response time to 911 calls; and it can
route an 800 call to the nearest vendor. ISDN supports ANI [INTM01].
10.2
CLI
Calling line identification (CLI): At a minimum, the calling line identification
includes a single calling party number; it may also include a second calling
party number, a calling party subaddress, and redirecting number
information. Calling line identification may not include any calling party
number due to interworking, or because of an interaction with the CLIR
supplementary service [STT100].
