122 Cabinet modular hardwareThe Link Peripheral Processor (LPP) is a high capacity vehicle for servicessuch as frame relay, packet switching, CCS7 call control and ethernetinterface. The LPP is required to support the Ethernet Interface Unit (EIU).Users of smaller Meridian SL-100 systems that do not require such highcapacity as the LPP, require a more economical method of accessingEIU/LPP services. The SSLPP is an alternative to a full Link PeripheralProcessor where:• The number of Link Interface Unit (LUI7) Application Specific Units(ASUs) desired does not make the full LPP a cost-effective option.• Offices lacking floor space near the core processor makes it impossibleto install an LPP cabinet.For more information about the FLIS, refer to the DMS-100 FamilyProvisioning Manual.Frame Supervisory PanelThe FSP distributes and controls power and alarms in the cabinet.Cooling unitThe high-capacity cooling unit consists of four, high-speed DC-powered fanblowers. Two of these four fans are operated with a separate power feedfor reliability.Power requirementThe LPP cabinet is powered by an external -48 V DC source provided by anCPDC. LPPs require the CPDC as a power source and cannot be poweredby an MCAM unit. The CPDC cabinet is described in "Maintenance andadministration cabinet modules" (page 127).Note: For detailed information about the LPP, refer to the PeripheralModules.Cabinetized Multi-Vendor InterfaceThe CMVI provides the multi-vendor interface between the Meridian SL-100system and the S/DMS AccessNode and other Remote Digital Terminals(RDTs). The Subscriber Carrier Module-100 Access, second version(SMA2), which resides in the CMVI cabinet, allows the Meridian SL-100system to connect to the Fiber Central Office Terminal (FCOT) in the S/DMSAccessNode or any T1-based access platform from any supplier thatconforms to the Bellcore standard TR-TSY-000303 (TR-303).Note: The SMA2 is also known as the Enhanced SMA (ESMA).Communication Server 2100Meridian SL-100 Product Guide555-4001-103 20.01 StandardSE09 20 October 2006Copyright © 2006, Nortel Networks Nortel Networks Confidential.
