How a CLID table is built
Prompts have been added to Overlay 15 that create a CLID table for a
customer. This table contains up to 4,000 CLID "entries." Each entry contains
unique information pertaining to CLID, as explained in the following
sections.
For users of an International Numbering Plan, the Meridian 1 now supports
multiple Prefix 1 (PFX1) and Prefix 2 (PFX2) contents, and multiple Home
Location Codes (HLOCs) and Local Steering Codes (LSCs), on a DN or DN
key basis.
For an International Numbering Plan, each CLID entry can now contain the
following:
• a 1 -6 digit national code for a home national number (HNTN), which is
the equivalent of PFX1
• a 1 -12 digit local code for a home local number (HLCL), which is the
equivalent of PFX2, or a one-12 digit Listed Directory Number for a
switchboard
• a 1- 7 digit Home Location Code (HLOC)
• a 1 -7 digit Local Steering Code (LSC)
Another new capability pertains to how the HLCL is constructed. A new
prompt, DIDN (which signifies "use DN as a DID number") in Overlay 15,
allows the HLCL to be built either using the digits in the HLCL plus the digits
of the active key (if DIDN is set to YES, the DN is considered to be a DID
number and is included in the CLID), or only the digits in the HLCL (if DIDN
is set to NO, the DN is not included in the CLID since it is not a DID number),
or based on a search on the DN keys, beginning from key 0, to find the CLID
to be used (DIDN is set to SRCH).

Enhancements" feature module in Networking Features and Services
