3-156 Datafilling ISDN on RSC-S International
ISDN operations
(continued)
Table ISGDEF contains service and channel information for the PM
which supports the DCH. The field in table ISGDEF isolates the DCH
card and the PM that houses the DCH card. The PMTYPE, PMNO
fields match the PMTYPE, PMNO, and DCHNO tuples in table
DCHINV. The D_CHNL subfield matches the PMTYPE, PMNO, and
DCHNO tuples in table DCHINV. The ISGNO tuple in table ISGDEF
matches the ISGNO tuple in table SPECCONN.
Table DCHINV contains information about peripherals that contain this
card in relation to the D-channel handler (DCH). The PMTYPE, PMNO
and DCHNO tuples match the PMTYPE and PMNO fields and the
D_CHNL subfield in table ISGDEF.
Table LTGRP can define a maximum of 32 logical terminal (LT) groups.
The system defines one of the groups as ISDN. The GROUP field in
table LTGRP matches field LTGRP in table LTDEF.
Table SPECCONN contains connections that you cannot modify through
the SERVORD. The SITE field in table SPECCONN matches the
NAME tuple from table SITE. This allows the system to identify
equipment for the switching unit and for all remote locations that
connect to the switching unit. Table SPECCONN duplicates datafill of
the XPMNO and XPMTYPE tuples in table LTCPSINV. This
duplication allows table SPECONN to access assignment of P-side links.
The OPTION tuple in this table matches the SCSEL field in table
LTMAP. The system supports a special connection on the P-side of the
RCO2.
Table LTMAP maps the ISDN LTs to a LEN or the TEI. Where table
LTMAP maps the ISDN LTs depends on the access privilege (AP). The
AP data matches the LTKEY tuple in table LTDEF. Table LTMAP uses
the LEN tuple, to access data for each line card slot. Table LTMAP uses
the LEN tuple entered in table LNINV. The SCSEL field in this table
matches the OPTION tuple in table SPECCONN.
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 matches the GROUP field in
table LTGRP.
