  • Page 17: Applications

    This has brought about exceptional growth in the demand for more bandwidth at reduced costs. One of the XDM-100's key features is its Layer 2 Ethernet capabilities, which offer carriers a clear migration path from pure TDM-based, legacy services to new value-added data services.

  • Page 18: Figure 2-1: Typical Ethernet Application

    As many customers insist on a fully guaranteed QoS, the XDM-100 enables you to provide a range of QoS levels for different customers, as well as several service levels for the same customer, if required.

  • Page 19: Metro-Access Applications

    PDH/Async, SDH/SONET, Gigabit Ethernet (GbE), and Fast Ethernet services at local Points of Presence (POPs). The XDM-100 also provides a service layer, which terminates WAN links and consolidates Ethernet traffic arriving from the local access network. Traffic can be carried to local GbE interfaces or routed to the metro-core network.

  • Page 20: Cellular Applications

    ♦ additional data services provided by cellular operators Functioning as both an ADM and a small cross-connect, the XDM-100 can easily convert from an aggregation component to a multi-ADM. This is performed once cellular operators decide to migrate from leased lines at the RAN to building their own infrastructure.
  • Page 21 The XDM-100 is designed to meet today’s growing network needs, such as the cost-reduction requirements needed in metropolitan and cellular applications. Optimized to meet the demands of today and tomorrow, the XDM-100 is the key building block for achieving highly competitive solutions. It enables operators to cater to unpredictable growth while avoiding the need to restructure their network.

    Ethernet, and the QoS, scalability, and survivability of SDH/SONET. Used in many subnetwork topologies, the XDM-100 can handle a mixture of point-to-point, hubbed, and meshed traffic patterns. This combined functionality means operators can benefit from improved network efficiency and significant savings in terms of cost and footprint.

  • Page 24: Metropolitan Transmission Networks

    – the need for additional bandwidth to meet constantly increasing telecommunication requirements. Designed to meet the demands of metropolitan access markets, the XDM-100 is a reliable and scalable network platform that helps providers minimize initial investment and adjust their growth to future demands.

  • Page 25: Tdm Configuration Options

    It operates at the STM-1/4/16 or OC-3/12/48 line bitrates. To operate the XDM-100 as a TM, a single aggregate is required. To operate it as an ADM, two are used. Any service can then be provisioned by adding the relevant I/O modules.

  • Page 26: Multi-Adm And Multi-Tm Modes

    The multi-ADM configuration is ideal for hub sites that close several rings. When configured as a multi-TM, the XDM-100 replaces several TMs, terminating the SDH/SONET line and delivering lower-rate services to end-users. This configuration is suitable for dual or multiple homing applications.

  • Page 27: Mxc Functionality

    Figure 3-2: XDM-100 cross-connect scheme In the redundant configuration, MXC-A and MXC-B cards operate in parallel. Each XDM-100 matrix permits full nonblocking connectivity at all VC or STS levels. The matrices are connected to all I/O modules, providing 1.25 Gbps capacity to each of them.

  • Page 32: Control And Communication

    4.1.1 Internal Control and Processing The MXC card provides central control, alarm, maintenance, and communication functions for the XDM-100 network element. It also communicates with the control processors of the various cards using a master-slave control hierarchy. The MXC can be protected with an identical MXC card. A faulty MXC (control function) card does not affect traffic even if only a single card is installed.

  • Page 33: Ne Software And Configuration Backup

    The XDM-100's control subsystem is separate from the traffic subsystem. In case of a failure or extraction of the active MXC card, traffic is not impaired if an MXC protection card exists.

  • Page 34: Timing And Synchronization

    System Design XDM® -100 After the XDM-100 is switched on, a BIT program is automatically activated for both the initialization and normal operation phases. The operator can stop its execution (and also restart it) from eNM LightSoft™. BIT testing covers general tests, including module presence tests and periodic sanity checks of I/O module processors.

  • Page 35: Figure 4-2: Timing Distribution Block Diagram

    These outputs can be used to synchronize any peripheral equipment or switch. The operator can remotely manage network synchronization using the EMS-XDM, and can select and determine the priority of each XDM-100 timing source reference. These sources can include any external reference clock, PDH/Async line signal, SDH/SONET line signal or internal clock, as described previously.
