78 Meridian SL-100 remote units• Simplified network planning and conservation of host resources through"back-door" dynamic trunking, which links the RSC to subtending PBXsand supports remotes off the RSC.MCRM-S (RSC-S)The Remote Switching Center-Second series (RSC-S) provides a maximumof 54 peripheral ports, in addition to ISDN capabilities. The Meridian SL-100packaging combines the RCC2 shelf, EXT shelf and the Power DistributionPanel (PDP) into one cabinet.The RSC-S lowers the costs per line over the lifetime of the equipment whiledelivering advanced digital services to remote subscribers. Like the MCRM,the MCRM-S can grow to meet increasing line demand through the additionof MCLM’s (ELCM’s), MCLM-Es (ISDN LCMs) and Intelligent PeripheralEquipment Columns (IPEC), as needed.The MCRM-S is also capable of supplying power to three IntelligentPeripheral Equipment (IPE) columns. This helps reduce the powerequipment costs for the remote.In a dual model, the RSC-S supports up to 10,000 lines (POTS at 3.0 CCSwith 30% intraswitching). This provides organizations with the ability tomaximize the services available from the Meridian SL-100 at an extendedlocation.Extended distance on MCRM-SEnterprises deploying the MCRM-S can reach farther than ever into thenetwork with Extended Distance Capability (EDC; BAS00009). With thispackage, the MCRM-S can be deployed at distances greater than 240 km(150 miles) from the host, depending on the transmission characteristics ofthe host links. Revenue-generating services, such as CLASS, ISDN, andACD, can penetrate significantly deeper into the network.The specific distance depends on the transmission facilities being used, aswell as traffic levels the switch has been engineered to meet. Verificationoffice activities have tested MCRM-S installations with EDC that serveapproximately 1,300 POTS subscribers at a simulated distance of 800 km(500 miles) from the host office, looping a combined transmission pathof copper, fiber and radio.This feature requires the NTMX76AB messaging circuit card.Communication Server 2100Meridian SL-100 Product Guide555-4001-103 20.01 StandardSE09 20 October 2006Copyright © 2006, Nortel Networks Nortel Networks Confidential.
