In today’s climate establishing theirown access networks is the key toprofitability in the fixed networkbusiness for every network opera-tor. With the Siemens FastLinkproduct users are offered DLC andFITL solutions which make thebusiness of arranging such net-works simple, flexible and eco-nomical.Even today, the most importantsources of income remain the tele-phony services (POTS, ISDN).Starting with a simple telephoneconnection and progressingthrough a second line for internetand fax to ISDN access, FastLinksupports these services and putsthe network operator in a positionto make high profits. For servicingbusiness and high-end private cus-tomers FastLink also makes itpossible to provide leased lines(voice and data) as well as broad-band data services, via DSL forexample.Its modularity and open architec-ture make FastLink quick and easyto integrate into any network envi-ronment. Additional services suchas broadband data services viaDSL can be provided though inte-gration of broadband componentsand powerful upgrade kits. Con-nection to any type of exchangevia standardized V5 interfaces haslong been normal practice formany network operators withFastLink. Preconfigured outdoortechnology proven on the worldmarket makes it unnecessary touse special air-conditioned operat-

modules are available for the OLT:• Crossconnect Multiplexer

• IP router or ATM switch XP140for inclusion of broadband

• Synchronous MultiplexerSMX1/4c or SMA1/4c

• Optical Multiplexer OMX16• 2-Mbit/s Line Equipment LE2• Terminal panels and distributorsThe Network Termination (NT)as compact desktop unit comple-menting the ONUs for leasedlines, online services, multimediaand broadband applications.The user-friendly management sys-tem AccessIntegrator (ACI) forcentral operation and monitoring isused for all FastLink components.The AccessIntegrator administers,monitors and manages the entireaccess network, which significant-ly reduces both the service andimplementation costs as well asthe ongoing operating costs. Atool for the mass provisioning ofsubscribers (MASSPROVI) consid-erably eases the task of creatinglarge numbers of subscribers. Themajor advantage of such anarrangement is the reduced outlayneeded for commissioning. TheACI with its client-server architec-ture can be used not only as amulti-station or standalone systembut also as a local craft terminal(LCT).

Introduction

FastLink’s telephony, data andbroadband services can be linkedinto a wide range of network struc-tures, as it supports point-to-point,point-to-multipoint, tree and ringarchitectures. This provides thenetwork operator with maximumflexibility in selecting a suitablestructure for his network.

There are powerful upgrade kitsavailable for both setting up newnetworks and safeguarding currentand future investments, ensuringthe provision of broadband ser-vices with the aid of xDSL-technol-ogy.

Using existing twin copper cablesin the subscriber access area,ADSL can be employed to transferdata at up to 8 Mbit/s (down-stream) and 800 kbit/s (upstream)between subscriber and InternetService Provider.

With high-speed Internet accessvia SHDSL data and voice is trans-ported using ATM at speeds of upto 2.3 Mbit/s.

The integration of ADSL and/orSHDSL components into FastLinknetworks will supplement theTDM-based narrowband signals byATM-based broadband signals.

This means that ATM-based broad-band transmission over the entiretransmission link, from the ISPinterface in the OLT up to the DSLmodem (broadband NT or NIC) atthe subscriber is possible.

Applications ...

The Optical Network Unit (ONU),as the central system componentfor telephony, data and broadbandservices, combines multiplexer andtransport facilities for optimumconfiguration of telecommunica-tion, city or corporate networks.

The network operator has a choiceof different ONU types for con-necting up to 2048 narrowbandand up to 80 broadband sub-scribers; FTTC variants for outdooruse or FTTO/FTTB variants forindoor operation.

A number of ONU variants providethe option of ODT functionality, sothat the ONU can also be used asan active hybrid distribution unitand thereby making a significantcontribution to reducing costs.

The number of multiplexers andthe number of interfaces can beexpanded as required, rangingfrom the small starter systemthrough to the comprehensive net-work.

A wide range of the latest trans-mission technologies is employedto ensure that the ONU can beused in all network areas.

Transmission with wavelength divi-sion multiplexing (WDM) on anoptical glass fiber can span up to50 km (without repeaters) andwhereas transmission with HDSLon e.g. 0.8-mm copper cable canspan up to 8 km (dependent oncable type).

The Optical Line Termination (OLT)is the FastLink component whichterminates the glass fiber and/orcopper cable network and imple-ments the interfaces to theexchange, to the data network andthe ATM network. The connectionto the exchange is made directlyvia digital 2-Mbit/s interfaces, withsignaling complying with the inter-national V5.1/V5.2 standards. Ifthese interfaces are not available,the OLT is connected using voicefrequency (VF) or 2-Mbit/s inter-faces with Channel Associated Signaling (CAS).

The broadband connection to theInternet Service Provider (ISP) ismade using IP routers or an ATMswitch function either via an Ether-net interface or via an optical STM-1 point-to-point connection.

In addition the OLT is the centralaccess point for the AccessIntegra-tor network management systemboth via a QD2 interface and via anSNMP interface.

FastLink’s Network Terminations(NTs) provide subscribers directlywith both high-speed digital inter-faces for online services and multi-media applications, such as video-on-demand, fast Internet or tele-learning, and also for all other stan-dard bit rates.

The NTs are compact desktopunits that connect via copper orfiber-optic cable to the ONU or theOLT cover a wide range of attrac-tive subscriber services.

Thus e.g. the ADSL NTs providean Ethernet interface for high-speed Internet connections andsimultaneous S0 or a/b interfacesfor voice transmission.

The OLT, as a central access tothe local exchange, the data net-works and ATM/IP networks, isphysically installed in one or moreETS racks which are set up withinbuildings on the exchange site.

The racks can be equipped with upto four shelves. In addition eachrack contains a terminal panel forpower supply, QD2 and clock dis-tribution.

For connecting glass fiber cables,depending on the number of con-nections required and the local cir-cumstances, a splice box or anoptical distribution frame (ODF)can be mounted in the rack.

For broadband connection to theInternet Service Provider an IProuter with ATM switch function isinstalled in the OLT rack.

The number of racks concernedand how they are equipped, aswell as the rack cabling are project-dependent.

The units are connected via thebackplane of the shelf, on whichthe terminal panel with its connec-tors for external and internalcabling is also mounted. The internconnections typically include con-nections between the individualshelves and connections betweenthe shelf and the rack terminalpanel. All other connections, to theexchange, the data network, theInternet or to the ONU, are exter-nal connections.

ATM Multiplexer Mini-DSLAM or Micro-DSLAM

The ATM multiplexers Mini- andMicro-DSLAM are a cost-optimizedvariant of the broadband equip-ment of FastLink and offer anATM-based network solution com-bining both broadband and narrow-band services. All services aretransmitted in end-to-end connec-tions with the aid of ATM cellsfrom the ATM network to the sub-scriber and back again.

For simultaneous transmission ofvoice and for example Internetdata on a shared twin copper wiredifferent xDSL techniques areused:

• ADSL with bit rates up to 8 Mbit/s for the transport ofdata in the direction of the subscriber (downstream) and

800 kbit/s in the opposite direc-tion (upstream)

• SHDSL with bit rates of 2.3 Mbit/s in both directions

The Mini-/Micro-DSLAM termi-nates the subscriber network, con-centrates all the broadband andnarrowband traffic and directs it viaSTM-1, E3 or IMA interfaces to theATM network.

The Mini-/Micro-DSLAM is moni-tored, supplied and controlled viathe 10BaseT interface which is ona central unit.

The following units are part of theMini-/Micro-DSLAM:

• Central Unit CLU

• Service Units (SUs) for broad-band applications

• Splitter units

Advantages of the Mini-/Micro-DSLAM

• ATM-based broadband transmis-sion over the entire transmissionlink, from the ISP interface inthe OLT to the DSL modem(broadband NT, NIC or IAD)

• Broadband and telephony ser-vices (ISDN/POTS) are transmit-ted via the ADSL interface on ashared twin copper wirebetween ONU and subscriber.The telephony and data signalsare split and merged using thesplitter units.

• Data and voice are transmittedsymmetrically as SHDSL multi-plex signals via a twin copperwire between the Mini-/Micro-DSLAM in the ONU and IADsinstalled at the subscribers. Nosplitter units are necessary.

• Transmission of n x E1 (n ≤ 8)by inverse multiplexing overATM (IMA).

• Alternatively to E1 (IMA) an E3or STM-1 signal can be used fortransmission between ONU andOLT.

• Interoperability with Voice overDSL (VoDSL) since the samecomponents and interfaces areused on the CPE and OLT side.

• Capacity increase to max. 160SHDSL interfaces in the Mini-DSLAM and max. 32 SHDSLinterfaces in the Micro-DSLAM(SU_SHDSL32) and expandableby additional VDSL services(SU_VDSL8) (on request)

Access Multiplexer AMXC

Access multiplexer AMXC is a fur-ther development of the AMX anda cost-optimized implementationof the subscriber-side access toFastLink, which, by concentratingsubscriber interfaces, makes itpossible to connect large numbersof subscribers using the sametransmission capacity.

The AMXC provides on the exchangeside both the open V5.2 or V5.1interface and an FastLink-internalconcentrating V5C interface in con-junction with crossconnect multi-plexer CMXII-V5.x. Thus, concentra-tion rates of e.g. 4 : 1 are possiblewithin the ONU itself.

Monitoring, supply and control ofthe AMXC is performed over theQD2-slave interface by the centralmeasurement and power supplymodule COMPS or COMPS2.

The following units are part of theAMXC:

• Central unit CUAII

• Line cards (LCs) for narrowbandapplications

• Power supply unit PSU

Advantages of the AMXC

• Increase in subscriber concen-tration per multiplexer:A CUAII serves up to 16 LCs.For each LC up to 8 ISDN or 32POTS interfaces are available.

This means that for each AMXCup to 512 subscribers (POTS)can be connected.

• Saving transmission capacity onthe systems side through theproprietary V5C interfacebetween AMXC and CMXII.For each CUAII up to four2-Mbit/s signals are transmittedfrom the AMXC to the CMXII.When the full concentrator func-tion is utilized the capacity ofmax. four 2-Mbit/s signals canbe transmitted over one 2-Mbit/s link (feeder).

• Saving the CMXII and transmis-sion capacity on the systemside by direct connection of theAMXC to the exchange via 2-Mbit/s interfaces with V5.2protocol. When the full concen-trator function is utilized thecapacity of max. four 2-Mbit/ssignals can be transmitted overone 2-Mbit/s link (feeder). In thestandard variant two 2-Mbit/slinks are provided (protectionmode).

• AMXC concept for individual 2-Mbit/s signals allows differenttransport paths in the directionof the OLT. If, for example, anindividual 2-Mbit/s transportchannel fails, the AMXC trafficload can be routed via theremaining transport channels. Tominimize the number of sub-scribers who are affected by thefailure of a module or a trans-port channel, two CUAII unitscan be used. Both CUAII unitsdivide up the traffic load andeach serve eight LCs.

Crossconnect MultiplexerCMXII-V5.x

As a gateway for POTS and ISDNservices between the dedicatednetwork and the public network,the crossconnect multiplexer con-verts CMXII-V5.x channel-associat-ed signaling (CAS) either into V5.1or into V5.2 switching protocols.Through connections of leasedlines or of CAS are also possible.The CMXII-V5.x consists of the following units:• Central unit CCU• Frame Relay unit V52FR• 2-Mbit/s interface unit PUCAS

and/or PU2+• SISA interface unit PUSISA

(optional)• Supervision unit MCU• Power supply PSCThe CCU, V52FR and PSC can beduplicated if module redundancy isrequired.With the PU2+ on the subscriberside, 2-Mbit/s signals with V5.1protocol can be switched or alsoconcentrated in accordance withV5.2. In addition, via FastLink-inter-nal signaling protocol (V5C) a con-centration of the subscribers canadditionally be undertaken.

Simultaneous operation of V5.1and V5.2 in the direction of theexchange is not possible.

The CMXII-V5.x is available in fourdifferent capacity stages:

• Single shelf (CMXII-LS)

• Combination of two shelves (CMXII-LS and CMXII-2S orCMXII-CS and CMXII-2S)

• Combination of three shelves (CMXII-CS and 2 x CMXII-2S)

This means that its overall capacitycan be adapted very variably to therequirements of the network.

Power supply to the CMXII-V5.x is–48 V/–60 V.
