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.
Disk Masher System
The Disk Masher System (.dms) was an often used method on the Amiga, to create a compressed image of a disk (usually floppy). The disk is read block-by-block, and thus its data structure is maintained. DMS won approval particularly in the demo scene and the Warez scene, since with this tool, disk images could generally be transferred easily with telecommunication modems to mailbox networks like FidoNet for efficient distribution.
The DiskMasher format is copyright-protected and has problems storing particular bit sequences due to bugs in the compression algorithm, but was widely used in the pirate and demo scenes. To avoid these issues, a number of other disk compressors were developed that used alternative disk reading and compression methods, for instance, xDM.

DMS-59
DMS-59 (Dual Monitor Solution, 59 pins) is generally used for computer video cards. It provides two DVI or VGA outputs in a single connector. An adapter cable is needed for conversion from DMS-59 (digital) to DVI (digital) or VGA (analog), and different types of adapter cables exist. The connector is four pins high and 15 pins wide, with a single pin missing from the bottom row, in a D-shaped shell, with thumbscrews.
The advantage of DMS-59 is its ability to support two high resolution displays, such as two DVI Single Link digital channels or two VGA analog channels, in a single DVI-size connector. The compact size lets a half-height card support two high resolution displays, and a full-height card (with two DMS-59 connectors) up to four high resolution displays.
The DMS-59 connector is used by AMD (AMD FireMV), Nvidia and Matrox for video cards sold in Lenovo Thinkcentres, Viglen Genies and Omninos, Dell, HP, and Sun computers. Some confusion has been caused by the fact that vendors label cards with DMS-59 as "supports DVI", but the cards have no DVI connectors built-in. Such cards, when equipped with only a VGA connector adapter cable, cannot be connected to a monitor with only a DVI-D input. A DMS-59 to DVI adapter cable needs to be used with such monitors.
