Meridian SuperNode for large applications

The Meridian SL-100 is a powerful communications system that combines
advanced hardware architecture with premier PBX software features. The
Meridian SL-100 is based on the highly successful technology Nortel
developed for Digital Multiplex System (DMS) central office switches.
These switches have set worldwide standards for reliability. The built-in
redundancy of all critical system components ensures system operations
integrity. As the largest member of the Meridian 1 family of sophisticated
business communications systems, the Meridian SL-100 has provided
superior service in a variety of industries for almost two decades.
The Meridian SL-100 supports a wide range of voice, data, video and
multimedia applications. The system can be flexibly configured to address
both current and future capacity and applications requirements as a result of
its 100,000 digital voice or data line capacity threshold. The Meridian SL-100
incorporates the Nortel advanced Dual Plane Common Control (DPCC)
design, which efficiently uses the system's processing power by providing
distributed control over many processors. The system's modular design
also allows easy upgrades as new processor technology becomes available.

Description
The switching network is a digital switching matrix that interconnects
the Peripheral Modules using Time Division Multiplexing (TDM). The
switching network has duplicate network planes for reliability. It is made
up of microprocessor-controlled digital switching Network Modules (NM)
and is connected to the SuperNode MS bus.
The Peripheral Modules (PMs) provide an interface between the switching
network and telephony terminals such as lines and trunks. They also
provide an interface between the Meridian SL-100 system and Remote
Digital Terminals (RDTs), access nodes and other vendors' switching
equipment.
The Input/Output Controller (IOC) provides an interface between the
messaging component (the SuperNode MS bus) and input/output devices
such as magnetic tape drives, disk drives, data links, video display
units and printers. A video display unit connected to the IOC is used
as a component of a Maintenance and Administration Position (MAP)
workstation. The MAP workstation provides a user interface to the
Meridian SL-100 system.
