• If the CLID entry of the originating DN specifies that it is to be identified
by its national number (CLASS_FMT=NTN in Overlay 15), then the
national public number associated with the originating DN
1
is delivered
(if the number is longer than 10 digits, only the first 10 will be delivered).
• If the originating set is assigned with an undefined CLID entry, then the
originating DN is delivered.
For a station (attendant)-to-CLASS set call, the calling number delivered to
the CLASS set will be one of the following:
• If CLID entry 0 specifies that it is to be identified by its internal DN
(CLASS_FMT=DN in Overlay 15), then the customer’s attendant DN
(the ATDN in Overlay 15) is delivered.
• If CLID entry 0 specifies that it is to be identified by its local number
(CLASS_FMT=LCL in Overlay 15), then the local public number
associated with the customer’s Listed Directory Number 0 (the LDN0 in
Overlay 15)
2
is delivered (if the number is longer than 10 digits, only the
first 10 will be delivered).
• If CLID entry 0 specifies that it is to be identified by its national number
(CLASS_FMT=NTN in Overlay 15), then the national public number
associated with the customer’s Listed Directory Number 0 (the LDN0
DN in LD Overlay)
3
is delivered (if the number is longer than 10 digits,
only the first 10 will be delivered).
• If CLID entry 0
4
is not configured, then the customer’s attendant DN (the
ATDN in LD Overlay) is delivered.

number by concatenating the customer defined home national number (entered using prompt HNTN and HLCL
in Overlay 15) and the originating DN.
2.The local public number is composed by the ISDN CLID Enhancements feature, which forms the calling
number for calls originated by an attendant by concatenating the customer defined home local number (entered
using prompt HLCL in Overlay 15) and LDN0.
3.The national public number is composed by the ISDN CLID Enhancements feature, which forms the calling
number for calls originated by an attendant by concatenating the customer defined home national number
(entered using prompt HNTN and HLCL in Overlay 15) and LDN0
4.The calling number for calls originated by an attendant is composed using CLID entry 0, as per the ISDN
