Assigning ringing to SCM-100U

Assigning ringing to the SCM-100U involves installing the proper ringing
generators and line cards at the DMS-100U and datafilling table RCUINV.

Ringing generator

The remote concentrator terminal (RCT) uses the NT3A39 ringing generator,
which supports single-party 20 Hz ringing and multiparty coded ringing. A
description of the NT3A39 ringing generator is in DMS-1 Urban Circuit Pack
Descriptions.

Line cards

The RCT uses the following line cards:
•
•
•
The line cards in the RCU must support ringing assigned to the SCM-100U.
Table RCUINV
Table RCUINV contains information on the RCU, including ringing
information. When assigning ringing to the SCM-100U, datafill the ringing
data in table RCUINV. A description of RCUINV and a sample of its datafill
is in the Customer Data Schema Reference Manual.

Assigning ringing to the OPM

Assigning ringing to the OPM is similar to assigning ringing to an RLCM,
except ringing generators are in the HIE shelf. As with the RLCM, the ringing
generators and line cards must be compatible with the type of ringing assigned
to the OPM.

Assigning ringing to the RSC

The RSC consists of LCM or RLCM and a remote cluster controller. Ringing
in the RSC is assigned to each LCM or RLCM. Assigning ringing to the LCM
and RLCM in the RSC is similar to assigning ringing to LCM and RLCM on
the DMS-100, except the ringing generators may be located in the remote
miscellaneous equipment (RME) frame or cabinet.
As with the LCM and RLCM, the ringing generators and line cards must be
compatible with the ringing assigned to the LCM or RLCM in the RSC.

Assigning ringing to lines

Ringing is assigned to lines by first placing them on the PM that supports the
appropriate ringing type. This is done by physically wiring the lines to line
