Ringing in Series II peripherals 3-9

DMS-100 Ringing System

Ringing generator capacity

Following are the capacities for the RCT ringing generators.

• QPP426—20 ringers/5 lines at a time

• QPP435—21 ringers/5 lines at a time

• QPP430—20 ringers/5 lines at a time

Ringing generator takeover

The RCT can be provisioned with backup ringing generators and power

converters. In the backup conﬁguration, the backup unit takes over if the

primary unit fails. Relays switch the ringing bus between the active and

standby ringing generators.

Circuitry on the primary ringing generator monitors the output of the active

ringing generator for failures. If a failure is detected, the monitoring circuitry

operates the relays to switch the active (faulty) ringing generator ofﬂine and

the standby ringing generator online. A ringing generator alarm is raised.

If the standby ringing generator is not provisioned, or is unavailable because

of a fault, circuitry on the faulty ringing generator will attempt to reset the

ringing generator automatically at 10-second intervals. If the reset fails, the

ringing bus, in this case, will be unavailable and call processing by the RCT

will be impacted.

SCM-100S

The SCM-100S provides a digital interface between the DMS-100 and the AT

Technologies, Inc. Subscriber Loop Carrier (SLC) 96. In the SCM-100S

system, the SLC-96 is referred to as the remote concentrator SLC-96 (RCS).

Refer to the documentation provided by AT Technologies, Inc. for a

description of the SLC-96.

The SCM-100S was introduced into the DMS-100 system by feature package

NTX398. You can ﬁnd documentation on the SCM-100S by referring to the

SMS Maintenance Manual

Ringing types supported by SCM-100S

The SCM-100S supports all currently available ringing schemes.
