This equipment forms part of the DMS-100 switching system, for years the cornerstone of the Northern Telecom (later Nortel Networks) product line. A Canadian-based company, Northern Telecom/Nortel Networks was one of the most important manufacturers of telecommunications equipment in the world in the 1990s. This particular unit was used by Nortel Networks personnel at its Ottawa Skyline campus (Baseline & Merivale Roads) for testing and product development.

Fonction

To provide data input/output to a digital telephone switching system.

Technique

The DMS-100 digital switching system is essentially an electronic computer operated by stored program control. The Input/Output Equipment (IOE) facilitates human access to this computer. It consists of two Priam 806 hard disk drives, a Cook Electric Co. model 2216 tape drive, an Input/Output Controller and a power supply. The tape drive is used to input program data to the DMS system. The disk drives hold billing records required to generate revenue for the telephone company. The Input/Output Controller consists of cards connecting the system to desktop VT100 or RS232 terminals used by technical personnel. (ref. 1)
