The access privilege (AP) determines if table LTMAP maps the ISDN
LTs to a LEN or the TEI. The AP data corresponds to the LTKEY tuple
in table LTDEF. Table LTMAP uses the LEN tuple to access data for
each line card slot. The LEN is originally entered in table LNINV.
Table LTDEF defines ISDN terminals and access privileges (AP) for the
type of service the terminal can access. The LTDEF field in this table
identifies an ISDN LT group. This field corresponds to the GROUP
field in table LTGRP.
Table KSETINV identifies an LTID as an ISDN keyset and defines the
attributes. The KSETLEN tuple in table KSETINV is the LTID tuple.
Table KSETLINE associates call appearances, ISDN LT call activators
and indicators, to directory numbers and various feature options. The
LTID tuple in table KSETLINE corresponds to the KSETLEN tuple in
table KSETINV.
Table KSETFEAT associates feature appearances, ISDN logical terminal
(LT) feature activators and indicators, with feature instances and various
feature options. The LTID tuple in table KSETFEAT corresponds to the
KSETLEN tuple in table KSETINV.
Table KSETKEYS defines the business set feature key templates. Use
this table to assign dedicated keys. These keys are used on several
business sets.
The translation process for the RSC-S with ISDN appears in the flowchart
that follows. Tables that are not necessary to implement ISDN on the
RSC-S appear in the basic call processing section.
