Introduction

Services offering for networks with FMX2R3.1

4Network Structures

Applicationsin Corporate Networks

Corporate networks of large com-panies and administrations, of banks, rail operators, utilities, alongpipelines, freeways and radio relaylinks require communication servicesthat are independent of the publicnetwork and tailored specifically to acompany.

Depending on the size and thestructural distribution of the company,the following applications will beneeded:

Access from analog and digitalterminals to a central node (e.g.PBX, computer center)

Connections between differentlocations

Access from remote outstations toa main station

The FMX2R3.1 provides the neces-sary equipment to meet theserequirements.

The flexibility of the multiplexer allowsany combination of subscriber inter-faces and software-controlled para-meter settings.

Digital as well as analog terminals cancommunicate directly with each otherin point-to-point or conference con-figurations or with a central node.

Terminated network structures andstandardized security managementguarantee secure data transport between remote computer networks.

Different shelves support custom andcost-optimized variation of the systemcomponents.

The following units are available:

The compact SNUS (Service Network Unit Shelf)

The FMX2S (Flexible Multiplexer 2 Shelf)

The MXS19 (Multiplexer Shelf 19'')

Desktop ONU 20 FTTO (Optical Network Unit for Indooroperation)

Over greater distances the SNUS canbe connected as required via STM-1/STM-4/34 Mbit/s optical or 2 Mbit/soptical/electrical.

Shelves FMX2S and MXS19 and alsothe desktop unit can be connected via2 Mbit/s (optical/ electrical).

The entire network can be controlledand monitored from one central loca-tion (e.g. from the computer center).

Applications in Public Networks

Both traditional and alternative carriersaim to build networks to meet thespecific requirements of businesscustomers.

The solution comprises setting up thebusiness customer's corporate net-work with FMX2R3.1 and linking thisvia a freely-selectable access point tothe FastLink system in the publicnetwork.

FastLink networks consist of subscri-ber ONUs (Optical Network Unit) andcentral OLT (Optical Line Termination)equipment and cater for all communi-cation services of private customers.The switching signals are transmittedin FastLink via the V5 protocol.

The channel-associated signaling ofthe corporate network is processed inthe OLT for the switching equipmenteither in accordance with V5.1 or forconcentrated traffic in accordancewith V5.2.

For this purpose the OLT housescrossconnect multiplexer CMXII-V5which converts channel-associatedsignaling into V5 protocols. Theconversion process involves assigningthe incoming channels from the sub-scribers either to up to 92 x 2-Mbit/sinterfaces in accordance with V5.1 orto up to 32 x 2-Mbit/s interfacesaccording to V5.2 in any arrangement.

5and Applications

In the OLT FastLink provides additio-nal options for transmission to thebroadband network or also to furtherdata networks.

The administration and supervision ofthe entire network, including thecorporate network can be undertakenusing the central managementsystem (AccessIntergator) of FastLink.This saves money on the cost of anadditional management system.

System Components

The following are available for thenetwork structures:

Multiplexer FMX2R3.1

Crossconnect multiplexer CMXC

Crossconnect multiplexer CMXII- for corporate networks

(CMXII-CAS)- as a gateway to V5.1/V5.2-

exchanges (CMXII-V5.x)

Synchronous multiplexer SMX1/4c

Optical line equipment OMX16

2-Mbit/s line equipment (LTx)

Network terminations (NTs)

The services are provided byMultiplexer FMX2R3.1, and include:

Analog services POTS, 2-wire OB, 2/4-wire Leased Lines (LL), 2/4-wirewith E&M

Data services with interfaces according to G.703, V.24, V.35, V.36 and X.21( 2 Mbit/s)

ISDN services ISDN-BA (Uk0, 4B3T/2B1Q)ISDN telephony (S0)

The FMX2R3.1 multiplexes the analogor digital signals of the subscriberinterfaces into one or two

employing the modern (SHDSL,WDM) and also conventionaltransmission procedures:

Copper

2 Mbit/s SHDSL

2 Mbit/s Uk2 or HDSL

2 Mbit/s transparent (G.703)

Glass fiber

2 x 2 Mbit/s single mode

2 Mbit/s single mode (Ug2)

Optical Line Equipment OMX16combines up to 16 x 2-Mbit/s signalsinto one 34-Mbit/s signal and preparesit for transmission over a singlemodeglass fiber.

Synchronous Multiplexer SMX1/4cprovides a choice of optical/electricalSTM-1 or an optical STM-4 interfacethat can be operated on a singlemode glass fiber in point-to-pointmode or in an SDH ring.

Remote outstations with a smallnumber of subscriber interfaces canbe supplied via Network Terminations(NT). The NTs are compact desktop orwall-mounted units connected direct-ly, either via copper or via glass fibercable, to the multiplexer or to 2-Mbit/sLTs and covering a wide range ofattractive subscriber services.

2-Mbit/s signals according to ITU-TG.703/G.704 and converts thesubscriber signaling into channel-asso-ciated signaling (CAS). FA signaling isalso available as a special signalingvariant.

Crossconnect Multiplexer CMXCserves as a small network node, typi-cally cross connecting the 2-Mbit/ssignals of the multiplexer, its 64-kbit/schannels or also its 8-kbit/s channels,the 64-kbit/s channels including theirsignaling information.

Crossconnect Multiplexer CMXIIwhich belongs to the FastLink systemcan be used as a larger network nodeand processes either channel-associated signaling or V5 protocol. In the latter case the channel-associa-ted signaling of the multiplexer isconverted in the CMXII into V5protocols.

Greater distances between thetelecommunications equipment willbe bridged as required by using a2-Mbit/s line equipment, optical lineequipment OMX16 or Synchronous Multiplexer SMX1/4c.

Both on the network side and on thesubscriber side 2-Mbit/s LineEquipment (LTx) can be used,

Network and Element Management

The components of the FMX2R3.1can be both remote controlled andalso themselves represent the accesspoint to the DCN (Data Communica-tion Network). They possess standardinterfaces according to QD2 for incorporation into the DCN as well asan F interface for local operating tasks.

The NTs are operated and monitoredvia the connected unit (multiplexerFMX2R3.1 or line equipment).

For transport of the control and transmission information channelswithin the transmission signal areused. In this way the entire networkcan be controlled from a suitable pointwith complete path managementwithout additional equipment.

The AccessIntegrator, SiemensOA&M solution for access products,supports both QD2 and SNMPnetwork elements and is thereforeexcellently well suited to manage-ment of narrowband and also broadband components.

Features of the ACI:

Windows NT-based graphical userinterface including support forvarious languages

Client-server architecture withdistributed processing

Optimum scalability for small andlarge networks

Completely object-oriented usersoftware

Standard interfaces for integrationinto higher-ranking networkmanagement systems

Network Management

The entire network is presented andcan be adapted with the network editor to the real network topology.

Configuration Management

Specific software is loaded on eachunit. The element and path parame-ters can be configured for operationand also for test purposes.

Performance Management

Performance data can be recorded onthe screen or in log files.

Fault Management

The entire network and each fault isdisplayed down to the smallestelement. With permanent errors the correspon-ding functional unit is switched offand a report is issued via the TMN.

Security Management

Access authorization with subdividedauthorization classes meet today'ssecurity requirements.
