Features and Services
Pre-release 24 functionality
Pre-release 24 common operation
The ANI DN is:
• the primary DN if originator is a set with Class of Service DNAA.
• the LDN0 if originator is an attendant with Class of Service DNAA.
• the ANDN configured on outgoing route if the originator is a set or an
attendant with Class of Service DNAD.
• part of CLID/OLI determined by RDNL (least significant digits), if
originator is an ISDN route (MCDN, QSIG, DPNSS, BRIT) and if
RDNL (Remote DN Length) not set to 0.
• the ANDN configured on incoming ISDN route if originator is an ISDN
route if RDNL set to 0 but ANDN configured.
• the ANDN configured on incoming non ISDN route (ANDN configured)
• the ANDN configured on outgoing route if originator is an ISDN route
with RDNL set to 0 and ANDN not configured.
• the ANDN configured on outgoing route if originator is a non-ISDN
route with ANDN not configured.
The ANI DN together with the local exchange code (LEC) shall always
comprise 7 digits. If it is less, additional digit(s), defined by the prompt
ADDG in Overlay 16 for the outgoing trunk route, is (are) inserted between
the subscriber category and the least significant digit of the extension number.
(see Figure 16.) The LEC sent to the CO is always the LEC programmed in
the CIS outgoing route.
If ANI DN + LEC together comprise more than seven digits, then the least
significant of the ANI DN digits are not used and are omitted.
