Administration of DMS ringing 4-3
DMS-100 Family DMS-100 Ringing System BASE15 and up
the SERVORD Reference Manual. Information regarding the relationship
between line cards and ringing types is summarized in the following table.
Table LMRNG
Table LMRNG contains ringing data for LM and RLM. A description of the
fields in table LMRNG, as well as a sample of datafill in table LMRNG, is in
the Customer Data Schema Reference Manual.
Assigning ringing to line concentrating modules
Assigning ringing to a line concentrating module (LCM) or remote line
concentrating module (RLCM) involves setting up the ringing generators for
the appropriate ringing signal, inserting the appropriate line cards, and
datafilling table LCMINV.
Setting up the LCM or RLCM ringing generators
The ringing generators in the LCM and RLCM are programmed by dual inline
package (DIP) switches on the ringing generator card. These switches must be
manually set to program the RG for the proper ringing signal.

LCMs).
