Meridian SL-100 hardware overview
This section describes the Meridian SL-100 circuit-switched hardware
components.
This chapter contains the following sections:
•"SuperNode generations" (page 13)
•"Meridian SL-100 platforms" (page 14)
•"Meridian SL-100 cabinets and frames" (page 16)
•"References" (page 18)
To provide large enterprise customers with maximum flexibility when
selecting their communication system, Nortel continues to offer the
circuit-switched Meridian SL-100 solution. The Meridian SL-100 combines
the best of both worlds: Nortel carrier-grade Digital Multiplex System
(DMS) and the world leading Meridian 1 Private Branch Exchange (PBX).
The Meridian SL-100’s architectural design which includes processing,
switching, access and call control layers, enables you to invest in new
technologies, such as IP technology, and to do so incrementally while
leveraging your investment in the rest of your Meridian SL-100 system.
The Meridian SL-100 provides fully integrated voice and data
communications and management. It serves as either a switching or
networking manager for corporate, military and institutional purposes. This
large-scale, software-controlled private switching system handles up to
60,000 digital voice or data connections, or a combination of both, to a wide
variety of other voice or data systems.
There are two types of Meridian SL-100 systems and they are differentiated
by the core processor. The first type is the SuperNode core with enhanced
call processing and handling capabilities. The second type is a scaled-down
version of the SuperNode core, called the SuperNode Space Enhanced
(SNSE) core, designed to serve smaller offices with a maximum of 36,000
lines.
Note: The number of lines supported depends on the switch
configuration, the feature implementation, the amount of ISDN line
penetration and the Centi-Call Seconds (CCS) per line.

12 Meridian SL-100 hardware overview
Figure 1 "Meridian SL-100 layered hardware architecture" (page 12)
illustrates the Meridian SL-100 hardware architecture.
Figure 1
Meridian SL-100 layered hardware architecture
Some of the attributes of the hardware architecture which distinguish the
Meridian SL-100 from the competition include the following:
•built-in redundancy which sets the standard in reliability
•small footprint and energy-efficient design to minimize facility costs
•modular design which allows organizations to scale the system to meet
their requirements
•clear evolutionary paths to minimize upgrade costs and maximize
investment protection, including the migration to the Communication
Server 2100 which is the next generation of the Meridian SL-100

SuperNode generations 13
SuperNode generations
The SuperNode generation of switches, which includes the SuperNode and
SuperNode SE systems, is based on evolutionary technology, yielding the
following improvements over the NT40 generation of switches:
•increased processing and call-handling capability
•reduced size
•improved reliability
SuperNode switches consists of the following three components:
•core - the control component.
•bus - the messaging component; hereafter called the Message Switch
(MS) bus or MS bus in this document to differentiate it from other types
of buses.
•link - the software infrastructure that implements public networking
standards including Common Channel Signaling and ISDN public
standards and protocols.
SuperNode switches have a distributed architecture and increased
processing capabilities, which provide an infrastructure for the development
of new features and services. The SuperNode system also provides an
interface to fiber transmission systems.
Overview of functional elements
All Meridian SL-100 systems consist of the same functional elements: the
control component, the messaging component, the switching network,
the peripheral modules and the input/output controller. Table 1 "Meridian
SL-100 functional elements" (page 13) describes the functional elements.
Table 1
Meridian SL-100 functional elements
Element Description
Control component The duplicated control component coordinates call processing, including
the actions of the switching network and of the Peripheral Modules. The
SuperNode control component is called the "core." The core’s major
elements are a Computing Module (CM) and System Load Module (SLM).
Note: The SuperNode messaging component is not contained in the
control component, but is separate and called the message switch bus.
Messaging
component The messaging component routes messages within the Meridian SL-100 system. The SuperNode messaging component is the MS bus. The MS
bus consists of duplicated message switches. The message switch is
based on the SuperNode CPU; thus, it uses some of the same software
as the Computing Module and the Central Control Complex CPU.

14 Meridian SL-100 hardware overview
Element Description
Switching network 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.
Peripheral Modules 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.
Input/Output
Controller 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.
Meridian SL-100 platforms
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.
Figure 2 "Meridian SuperNode" (page 15) shows an example of a Meridian
SuperNode.

Meridian SuperNode SE (Space Enhanced) for smaller
applications
As a smaller alternate solution to the Meridian SuperNode, the SuperNode
SE (SNSE) is specifically designed for lower line-size (4,000 to 50,000)
application-intensive requirements. The specific number of provisionable
lines is dependent on the actual switch configuration, Centi-Call Seconds
(CCS) per line and the actual mix of feature penetration.
The SNSE configuration provides the platform for current and future
Meridian SL-100 applications and features required for the small switch
market (see Figure 3 "Meridian SuperNode SE" (page 15)).

Meridian SL-100 cabinets and frames
Cabinet concept
The Meridian SL-100 system cabinet structure consists of basic hardware
switching modules mounted in 1.8 m (6 ft.) gray or brown cabinets.
Modular design
Modular design techniques are used in the development of both the software
and hardware. Modularity can be thought of as the implementation of a
complex system through a set of functional units or modules connected by
well-defined interfaces. As a result of proper module and interface design,
the various units can be connected, disconnected, modified or improved
without affecting either the operation of the other modules in the system
or the system as a whole.
This modularity gives the system flexibility in physical layout and function,
in providing special features and in system expansion. The cabinetized
Meridian SL-100 can be adapted to specific customer line, trunk and service
circuit requirements through additional engineering.
Advantages of the cabinet
The cabinetized Meridian SL-100 offers these benefits:
•Provides pre-cabled, factory-assembled, and tested cabinets; thus,
reducing on-site installation or commissioning intervals.
•Provides a modular system that easily expands and accommodates
variations in system size and feature choices and allows integration
of future system enhancements.
•Eliminates the need for additional external earthquake bracing by using
prebraced steel cabinets.
•Presents a modern, computer-style appearance, ideally suited for
computer rooms having raised flooring and low, suspended ceilings.
•Shortens delivery time.

•Simplifies system expansions.
Dimensions
Current Meridian SL-100 hardware is housed in cabinets or frames with the
following dimensions:
•C42 cabinet: 183 cm high 107 cm wide 72 cm deep (72" 42" 28")
•C28 cabinet: 183 cm high 72 CM wide 72 cm deep (72" 27" 28")
•Open frame: 213 cm high 72 cm wide 46 cm deep (84" 28 18")
Each cabinet or frame contains four shelves with slots for equipment (for
example, card slots for inserting circuit cards). Cabinets are equipped with
double doors on both the front and rear to provide convenient access for
maintenance personnel.
Figure 4 "Dimensions of current Meridian SL-100 cabinets" (page 17)
illustrates the dimensions of C42 and C28 cabinets and lists the hardware
units that can be housed in each one. An open frame can house the same
type of units as C28 cabinets.
Figure 4
Dimensions of current Meridian SL-100 cabinets
Note: Standard Meridian SL-100 frames are also used to house
the Spectrum Peripheral Module. The dimensions of the Spectrum
Peripheral Module hardware are smaller than those of equivalent
Extended Peripheral Module (XPM) units, but to minimize costs adapter
brackets are used to house Spectrum Peripheral Modules in existing
frames. Overall footprint can still be reduced, because access to all
cards in the Spectrum Peripheral Module double-height shelves is from
