DMS-100

The DMS-100 Switch Digital Multiplex System (DMS) was a line of telephone exchange switches manufactured by Northern Telecom. Designed during the 1970s and released in 1979, it can control 100,000 telephone lines.
The purpose of the DMS-100 Switch is to provide local service and connections to the PSTN public telephone network. It is designed to deliver services over subscribers' telephone lines and trunks. It provides Plain Old Telephone Service (POTS), mobility management for cellular phone systems, sophisticated business services such as Automatic Call Distribution (ACD), Integrated Services Digital Network (ISDN), and Meridian Digital Centrex (MDC), formerly called Integrated Business Network (IBN). It also provides Intelligent Network functions (AIN, CS1-R, ETSI INAP). It is used in countries throughout the world. Much of the hardware used in the DMS-100, with the possible exception of the Line Cards, is used in other members of the DMS family, including the DMS-200 Toll switch.
==Hardware==
All power distribution is at -48 VDC (nominal), from which DC to DC converters on every shelf provide other necessary voltages.
