CWDM capability on the same single platform. This establishes a clear lead for metro-access applications with escalating bandwidth requirements. The XDM-100 is compact and resilient, making it perfectly suited for both ♦ indoor and outdoor enclosures. Due to its extended operating temperature range, it is also most suitable for harsh environmental conditions.
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.
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.
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.
♦ 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.

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.
– 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.
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.
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.
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.
QoS demands. As a one-edge node platform, the XDM-100 supports data applications with Ethernet Layer 2 services via a special Ethernet module called the EIS-M (Ethernet Interface and Switching Module).
♦ Data and other digital services ♦ The XDM-100 also supports a wide range of I/O interfaces and Ethernet Layer 2 services, enabling its deployment in transmission networks, as follows: SDH: E1, E3, DS-3, STM-1 electrical interface, STM-1 optical interface, ♦...
Ethernet and SDH/SONET lines. Its modular architecture enables network operators to start small, and then simply and cost-effectively expand their systems to higher capacities as demand grows. This chapter describes the following XDM-100 component functions: Traffic and cross-connectivity, including: ♦...
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.
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.
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.
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.
The link is fully redundant at intershelf levels. Figure 4-4 illustrates the simplified XDM-100 overall block diagram. It provides an overview of both the physical and functional partitioning of the system. ECI Telecom Ltd. Proprietary...
The XDM-100 supports PIM modules for different bitrates: 2 Mbps (E1), 34 Mbps (E3), 45 Mbps (DS-3), and 52 Mbps (STS-1). A PIM module occupies a single I/O slot in the XDM-100 shelf, providing all the functionality required to deploy a transport network, including Performance Monitoring (PM) for PDH/Async interfaces, 2 Mbps retiming (for PBAX synchronization), and 2 Mbps/45 Mbps frame for data applications.
♦ 4.4.3 EIS-M (Ethernet Interface and Switching Module) The EIS-M is used in the XDM-100 to provide Layer 2 Ethernet services. By simply plugging in the EIS-M, carriers are ready to roll out a new array of revenue-generating services. The EIS-M's Ethernet interfaces are connected to the end user’s Ethernet equipment.
Ethernet service. Each packet can be delivered through several EIS-Ms before arriving at its final destination. An XDM-100 shelf can accommodate up to four EIS-Ms, either working independently or protecting each other. There are three types of EIS-Ms with different types of ports, as described in the...
System Design 4.5 OverHead Unit (OHU) Module The XDM-100 OHU module provides orderwire functionality for field technicians, supporting conference calls between up to 10 participants. The OHU can be accommodated in any of the shelf’s I/O slots. In addition, the module supports: Interface overhead access bytes towards the MXC card ♦...
DC power source lines. The XDM-100 features a fully redundant power feed subsystem with two external power inputs available. A redundant xINF unit is located on each MXC card. The filter can be connected to both power inputs and distributes the -48 to -60 V DC battery plant inputs to all cards and modules via fully redundant power buses.
The XDM-100 provides hardware protection to the electrical tributary modules with the Tributary Protection Unit (TPU). The TPU is an expansion shelf plugged on the top of the XDM-100. Connected to the control and power of the XDM-100 shelf, it becomes an integral part of the platform.
The system’s protection schemes comprise highly reliable trail protection arrangements, as well as equipment duplication on all units. The XDM-100 also provides protection for internal traffic paths. All traffic is fully redundant within the system and is routed via separate traffic paths and hardware units.
Path protection is supported by all aggregate and tributary I/O modules, and VC/STS trail protection may be selected from any two SIM/SAM interfaces. This flexibility enables the XDM-100 to integrate with other network nodes and provides end-to-end network path protection regardless of the network’s topology. This integrated path protection capability enables operators to smoothly integrate the XDM-100 into existing networks.
Route diversity protection ensures seamless protection integration and interoperability of XDM-100 systems with any other SDH/SONET equipment. Figure 5-1 shows a protection implementation when the XDM-100 is integrated with ECI Telecom's Optical Networks Division's XDM-1000, and Figure 5-2 shows another implementation with SYNCOM™ or third party SDH/SONET add/drop multiplexers.
Protection and Redundancy XDM® -100 Dual route path protection also allows the XDM-100 to work in conjunction with other vendors’ SDH/SONET equipment at various transmission rates, regardless of topology and equipment (see Figure 5-3). Figure 5-3: Integration with other vendors’ SDH/SONET equipment 5.1.2 SubNetwork Connection Protection (SNCP)
The XDM-100 supports MSP-L/APS in all optical or electrical SIM/SAM line modules (STM-1/OC-3, STM-4/OC-12, and STM-16/OC-48). MSP 1+1/APS 1+1 unidirectional and bidirectional modes are also supported. As in SNCP/UPSR and path protection, in the MSP/APS mode, the XDM-100 provides protection for both fiber and hardware faults. 417006-2005-013-A02...
Protection and Redundancy XDM® -100 Figure 5-4 shows a four-fiber star XDM-100 with all links protected. This ensures uninterrupted service even in the case of a double fault. In this case, the system automatically performs MSP/APS switching within 50 ms.
In the example in Figure 5-5, if there is a fiber cut between sites A and D, traffic is transported through sites B and C on the black portion of the fiber that runs clockwise. Figure 5-5: Two-fiber MS-SPRring/BLSR protection 417006-2005-013-A02 ECI Telecom Ltd. Proprietary...
