Megaplex-2100/2104Modular Integrated Access MultiplexersMegaplex-2100/2104 is a modularintegrated access TDM multiplexer, whichintegrates multiple dedicated data, voice,ISDN and LAN channels over multiple main(network) links. Megaplex equipped with8-port main link modules in conjunctionwith the 12-port high-speed modulefeatures a traffic payload capacity of up to248 DS0 timeslots. The modules ofversion 11 and lower support up to124 DS0 timeslots (8 Mbps).The flexible, modular Megaplex with a widechoice of I/O (user interface) modules wasdesigned for applications ranging fromsmall campus networks to multi-sitecorporate networks or extensive carrieraccess solutions. Due to Megaplex’sstandards adherence, central office basedcross-connect units (DACS) can separatevoice and data, sending each to theappropriate carrier or service.Megaplex enables carriers to successfullydeploy bundled services, ISDN services andInternet access. The integration of a broadrange of services makes Megaplex acost-effective access device, with reduceddeployment and maintenance costs.Megaplex with TDMoIP technologyprovides a cost-effective, versatile andmodular solution for transmitting legacyTDM traffic over IP networks. This isespecially suitable for large corporations,utilities or power companies that areseeking a gradual migration to IPnetworks.The equipment conforms to internationalstandards, ensuring compatibility inmulti-vendor environments worldwide.TDMOIPMegaplex offers an optional IP main linkmodule that transmits TDM traffic directlyover IP networks. This TDMoIP accessmodule converts user TDM traffic into IPpackets transmitted on 10/100BaseT or100BaseF Ethernet networks.CHASSISThe chassis is available in two basicvariants:• Megaplex-2100 (4U high) chassisproviding slots for up to 12 main linkand I/O modules• Megaplex-2104 (2U high) chassisproviding slots for up to 5 main linkand I/O modules.

TIMINGMultiple system timing options areavailable:• Internal crystal oscillator clock• Clock received from any link(loopback)• Clock from any high speed modulechannel• External station (master) clock• Adaptive timing received from anybundle (with ML-IP only).Any clock source can be set as fallback inthe event of primary clock source failure.SYSTEM REDUNDANCYMegaplex’s modular, distributedarchitecture enables redundancy atdifferent levels of the network andprovides a system with no single point offailure.System hardware redundancy is attainedby an optional redundant power supplyand common logic module (MP-2100chassis only).1:1 protection switching on the main linkmodules protects against network or cablefailure. Additional ML modules can beinstalled and interconnected via Y-cablesto provide protection against ML hardwarefailures.Bundle redundancy provides backup for IPtransmissions (functions similarly to E1/T1link “parallel TX” redundancy).In case of link failure, Megaplex activatesalternate routing. This is achieved bystoring multiple configuration databasesand flipping (switching) between them incase of any network event.The Megaplex system also supports twoRAD proprietary types of ring redundancy,provided by its main link modules:• E1/T1 Ring: Similar to SDH, the E1/T1ring features ring redundancy in aclosed dual-ring topology: one pathpropagates data “clockwise” and theother “counterclockwise”. EachMegaplex can receive data through twodifferent paths, and selects only thesignal received through one of thepaths for processing. In case of failure,the failed segment is bypassed byusing the second path, providingself-healing in less than five seconds.• RFER: The TDMoIP link module featuresRAD’s Resilient Fast Ethernet Ring(RFER) technology for creatingself-healing Ethernet ring networks.RFER reroutes traffic within 50 msec ofa ring segment failure, providing fastredundancy performance similar toSDH networks. Survivability is furtherenhanced by RFER’s scalable supportfor multiple rings. RFER can carry up to40 E1 or 50 T1 links with no limit onthe number of nodes.The built-in, non-blocking, DS0cross-connect matrix enables routing anychannel’s timeslots to any link. This allowsMegaplex to maximize its efficiency bysplitting voice and data channels andredirecting the traffic, via separate links,to the appropriate service.The cross-connect matrix also enablesrouting timeslots from any link to anyother link. This facilitates drop insert,bypass or broadcast multi-linkapplications.Figure 1. Point-to-Point TopologyMegaplex is suitable for integrating all the traffic requirements between two sites, over a wide variety of E1/T1 links: leasedlines, fiber optic, SHDSL, radio or satellite.Multiple fractional or full E1/T1 links provide load sharing between the links, as well as automatic backup, with prioritizationof voice and data services. Link redundancy is supported, providing 1:1 protective switching between any two links (within50 msec between dual links of same ML module).

Megaplex-2100/2104Modular Integrated Access MultiplexersA total of 124 timeslots can be allocated,either for transmission of I/O channels orfor bypassing timeslots between links ofdifferent modules.R2 SIGNALINGMain Link (ML) modules support R2signaling with transparent MFC/DECADIC,so that Megaplex can be placed betweenan older R2-PBX and a digital (E1-CAS)PBX. The MFC/DECADIC signaling is notterminated by Megaplex, but passed on tothe PBX. In addition to the ITU-T standardR2 protocol, several predefined nationalPTT protocols, as well as user-definedvariations, are also supported. Since theR2 signaling support is provided by theML, all voice module types support R2.COMMON LOGIC MODULESThe Common Logic (CL) module controlsthe Megaplex operation and is theinterface for its configuration andmanagement. It stores the applicationsoftware and up to 10 configurationdatabases (depending on complexity) formultiple independent configurations. TheCL also stores all system eventinformation. Flash EPROM for softwaredownload is provided.Two dedicated ports are provided on theCL module for management purposes. Oneport has a 9-pin DCE interface for directconnection of a management terminal orPC. The other is ordered with one of thefollowing interface options:• Ethernet 10BaseT (UTP)• Ethernet 10Base2 (BNC)• V.24/RS-232 DTE.An input voltage detector, intended forsensing external events (coming fromtemperature alarm sensors etc), generatesinternal alarms, which are sent to the NMSstation and reported to the user.Two outbound relays can be assigned tobe triggered by any user-selected major orminor alarm, for routing of Megaplexalarms to outside indicators, such asbuzzers and bells.Figure 2. Resilient Fast Ethernet Ring (RFER) Provides 50-msec Self-Healing IP NetworksMegaplex ML-IP with RAD’s RFER technology, enables corporations, campuses, utilities, and transportation companies to createhighly reliable IP networks with 50-msec link protection switching, using dark fiber or copper wire in a ring topology.

MAIN LINK MODULESE1/T1 Main LinksMegaplex TDM E1/T1 main link modulesallow direct connection to a wide range ofservices, eliminating the need for externalequipment. Multiple active links canoperate in each chassis. Additionalmodules can also be installed for linkredundancy.The various ML modules can be configuredfor a broad range of applications: fromsingle link non-redundant operation, tomultiple full or fractional E1/T1 linkapplications requiring drop & insert andbroadcast.E1/T1 link modules with built-in fiber opticmodems (range up to 100 km/62 miles) orE1 link modules with xDSL modems (rangeup to 10.6 km/6.6 miles) are available.These special links reduce the cost of localloop solutions by lowering equipmentdeployment and maintenance costs.The dual-trunk main link modules increaseefficiency and provide 1:1 protectiveswitching between the two links within50 msec.The high-density 8-port E1, T1 and SHDSLmodules increase the Megaplex TDMcapacity up to 16 Mbps.TDMoIP Main LinkThe unique ML-IP main link moduleconverts the TDM bit stream deliveredover the internal Megaplex back plane intoIP packets, for transmission over IPnetworks. ML-IP features three Ethernetports, with 10/100BaseT or 100BaseFinterfaces. The module conforms to IEEE802.3 and 802.3u and provides reliable,high quality of service (QoS), includingVLAN tagging and priority labeling (ToS).ML-IP places TDM timeslots into IP bundleswith VLAN tagging required bypoint-to-multipoint applications. Duplicatebundles can be transmitted simultaneouslyon different paths for redundancy.Figure 3. Megaplex-2100 in a Tetra RingRAD’s DXC (Digital Cross-connect) DACS complements Megaplex’s own cross-connect capabilities, to provide acomprehensive network solution. DXC flexibly routes timeslots between different Megaplex and other E1/T1 sites. Theequipment in all the sites is easily controlled and monitored by an integrated network management system.

Megaplex-2100/2104Modular Integrated Access MultiplexersI/O MODULESUp to 11 I/O modules of any kind can beplaced in an MP-2100 chassis (up to 4 I/Omodules in an MP-2104). If more I/Omodules are required, Megaplex units canbe cascaded.High-Speed Data ModulesHigh speed data interface modulesprovide leased line data services,operating at multiples of 56 or 64 kbps,up to 2.048 Mbps, connecting routers,bridges, front-end processors, etc.E1 interface modules with built-in xDSLmodems enable cost-effective long-rangedeployment of high speed services over2- or 4-wire copper lines. Range is up to4.0 km.ISDN BRI (“U” or “S”) modules extendISDN services over non-ISDN facilities,supporting data, voice and Ethernetapplications. The “U” interface modulesemploy IDSL technology for “last mile”applications.An IEEE C37.94-compliant n x 64 fiber datamodule is provided for transportingteleprotection data.Low Speed Data ModulesSub-rate multiplexer modules for lowspeed (2.4 to 19.2 kbps) synchronous andasynchronous data channels employstandard X.50, X.58 or SDM (DS0-B)multiplexing techniques.Low-speed modules with sync/asyncV.24/RS-232 channels, with independentchannel rates of up to 64 kbps areavailable. End-to-end control signals aresupported.Voice/Fax and Voice CompressionModulesVoice/fax modules transmit voice at tollquality using standard PCM (ITU-T G.711),as well as ADPCM (G.726), MPMLQ(G.723.1), or P-CELP 4.8 kbps compression.Standard analog interfaces are available fordirect connection to POTS, publicpayphones, LB (local battery) field phones,PBX extensions or 2/4-wire E&M trunks.Alternatively, voice compression moduleswith E1 and T1 digital PBX interfaces areavailable. Loop, wink and ground-startsignaling are also supported.Digital voice compression modulesconnect PBX trunks with greaterbandwidth utilization (compression ratioof up to 10:1). The modules employ achoice of high quality voice compressionmethods, including G.723.1 at 6.4 kbpsper channel, or G.729A at 8 kbps. Themodules support Group III fax and modemrelay, at user-selectable standard rates ofup to 14.4 kbps, featuring transparenttimeslot transfer, voice activity detection,silence suppression, and comfort noisegeneration. Module versions are offeredwith single/dual T1 (up to 24/48channels), or single/dual E1 (up to 30/60channels) interfaces.A special ”omnibus“ module provides fourtoll-quality voice channels to supportapplications (see Figure 4) where a mastersite needs to communicate with multipleremote stations simultaneously (such asto broadcast an important message).LAN ModulesEthernet router/bridge modules enableLAN to LAN extension over E1/T1 services,offering various L2 capabilities.MANAGEMENTMegaplex can be fully configured locally,using an ASCII terminal. It can also bemanaged remotely via Telnet, SNMPelement management applications, orend-to-end path management application.Megaplex communicates with themanagement station by means of itsSNMP agent (via a SLIP/PPP or TCP/IPconnection). Network managementapplications provide centralized control ofall network nodes, including interfaceconfiguration, connection setup, alarmsand monitoring.The user-friendly GUI-based RADviewnetwork management applicationsfacilitate management of both individualunits and entire networks.The RADview-SC/TDM application enablesend-to-end path management of MAPdevices, providing physical and logicalgraphic views of all network links andservice paths of the system.The management connection can beestablished by the following methods:• Out-of-band, using the Ethernetmanagement port. This simpleand efficient method takesadvantage of IP bandwidth ondemand, while saving link bandwidthfor user traffic• Inband over a dedicated timeslot,supporting standard PPP, FRencapsulation, and RIP2 protocols• Over a modem link or over a FRAD,via the control port of the remoteunit.Figure 4.
