ISDN Primary Rate Interface
1.5 Mb PRI implementation
Description
Home location code (NARS), prompted when
PRA = YES.
One to four digit Local Steering Code, if required in the
Coordinated Dialing Plan (CDP). LSCs are required
only if the CDP DNs are longer than the local PDNs.
The CLID sent for a CDP call is composed of the LSC
defined in LD 15 plus the PDN of the calling set.
Various ISDN network features depend on the CLID as
the "return address" for sending feature control
messages.
Multiple LSCs can be defined in LD 87 for CDP, but only
one LSC can be defined here for CLID.
