SuperNode generations 13SuperNode generationsThe SuperNode generation of switches, which includes the SuperNode andSuperNode SE systems, is based on evolutionary technology, yielding thefollowing improvements over the NT40 generation of switches:• increased processing and call-handling capability• reduced size• improved reliabilitySuperNode 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 typesof buses.• link - the software infrastructure that implements public networkingstandards including Common Channel Signaling and ISDN publicstandards and protocols.SuperNode switches have a distributed architecture and increasedprocessing capabilities, which provide an infrastructure for the developmentof new features and services. The SuperNode system also provides aninterface to fiber transmission systems.Overview of functional elementsAll Meridian SL-100 systems consist of the same functional elements: thecontrol component, the messaging component, the switching network,the peripheral modules and the input/output controller. Table 1 "MeridianSL-100 functional elements" (page 13) describes the functional elements.Table 1Meridian SL-100 functional elementsElement DescriptionControl component The duplicated control component coordinates call processing, includingthe actions of the switching network and of the Peripheral Modules. TheSuperNode control component is called the "core." The core’s majorelements are a Computing Module (CM) and System Load Module (SLM).Note: The SuperNode messaging component is not contained in thecontrol component, but is separate and called the message switch bus.MessagingcomponentThe messaging component routes messages within the Meridian SL-100system. The SuperNode messaging component is the MS bus. The MSbus consists of duplicated message switches. The message switch isbased on the SuperNode CPU; thus, it uses some of the same softwareas the Computing Module and the Central Control Complex CPU.Communication Server 2100Meridian SL-100 Product Guide555-4001-103 20.01 StandardSE09 20 October 2006Copyright © 2006, Nortel Networks Nortel Networks Confidential.
