4-4 Administration of DMS ringing

Line cards

As with the LM and RLM, the LCM and RLCM must contain line cards that
support the ringing type assigned to them. The LCM and RLCM use the same
line cards as the LM and RLM. The table "Line class codes by line card type
and ring code" lists the line cards and the ringing types they support.
When assigning ringing to an LCM or RLCM, you must ensure that
compatible line cards are installed.
Table LCMINV
Table LCMINV contains information on LCMs and RLCMs, including
ringing information. A description of Table LCMINV and a sample of datafill
from Table LCMINV are in the Customer Data Schema Reference Manual. In
an LCE, both LCMs must be assigned the same ringing type. Also, the ringing
type datafilled in table LCMINV must match the ringing scheme set by the DIP
switches on the ringing generators.

Assigning ringing to SCM-100R

The SCM-100R supports the following type of ringing:
•
•
•
•
In order to assign ringing to the SCM-100R, the appropriate ringing generators
and line cards must be installed at the RCT, and table RCTINV must be
datafilled.

Ringing generators

The RCT in the SCM-100R system uses the following ringing generators:
•
•
•
•
•
The appropriate ringing generators must be installed in the RCT to support the
type of ringing assigned to the SCM-100R.
