1.2 XDM®-100 – A Genuine MSPP in a Compact
Package
Today's cellular and access networks demand add-on service capabilities for a vast
array of systems, such as 2G, 2.5G and 3G base-station traffic, SDH/SONET optical
rings, chains, point-to-point connections and radio links. At the same time, operators
and service providers are expected to be able to provide broadband services to their
enterprise customers over the same infrastructure, while reducing power
consumption, space requirements and overall cost. ECI Telecom's XDM-100
miniature MSPP is the answer to all of these requirements – and more.

XDM® -100 Introduction
417006-2005-013-A02 ECI Telecom Ltd. Proprietary 1-3
MSPPs have begun to play a critical role in the journey from legacy to
next-generation networks. The XDM-100 MSPP enables carriers to leverage their
SDH/SONET installed base while offering an increasing mix of services to their
customers. With its high modularity and flexibility of interfaces, the XDM-100
MSPP preserves the high availability and quality of networking services.
Designed to provide a swift response to evolving network requirements, the
XDM-100 brings greater levels of flexibility to metropolitan and cellular networks,
and has emerged as a solid solution for these focused and highly cost-sensitive
markets.
1.3 Features and Benefits
ECI Telecom's XDM-100 miniature MSPP delivers a cost-effective and affordable
mix of Ethernet, SDH/SONET and PDH/Async services, resulting in new
revenue-generating opportunities. It offers a wide variety of features and benefits,
including:
♦ Gradual in-service capacity expansion based on service provisioning needs.
An optical connection operating at a specific STM/OC rate can be upgraded
from STM-1/OC-3 to STM-4/16/OC-12/48 without affecting traffic. This
high adaptability and "build-as-you-grow"™ architecture translates into
significant savings in both OPEX and CAPEX.
♦ Sublambda grooming enables high utilization of existing fibers and top
efficiency in transmission of different types of services.
♦ Multi-ADM and cross-connect functionality make the XDM-100 ideal for
deployment in flexible network topologies, such as ring, mesh, and star.
♦ The XDM®-100H cost option supplements all of the above-mentioned
features with 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.

Applications
The XDM®-100 is a flexible MSPP that can be deployed in various applications. Its
exceptional capacity and modularity, combined with its small footprint and
economical cost, make it ideal for metro-access and cellular networks.
The XDM-100 boosts service provisioning, aggregation and transport from
metro-edge to metro-core, converting it into an essential element in today’s
networks.
2.1 Data Applications
Ethernet services have been the driving force in the telecommunications industry in
recent years, providing a new approach to data service provisioning and
connectivity. 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. The XDM-100 Ethernet capabilities enable carriers to
provide services, such as Ethernet Private Lines (replacing traditional TDM leased-
line services), Ethernet Virtual Private Lines using shared Ethernet rings, and
Ethernet Virtual Private LAN services, extending corporate LANs over the WAN.
All services can be offered with Quality of Service (QoS) and Service Level
Agreement (SLA) assurances, controlled and managed by ECI Telecom's Optical
Networks Division's multidimensional eNM LightSoft™ Network Management
System (NMS).

Figure 2-1: Typical Ethernet application
The XDM-100 polices and queues traffic to ensure QoS and manages bandwidth
resources at the packet level. 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.

XDM® -100 Applications
417006-2005-013-A02 ECI Telecom Ltd. Proprietary 2-3
2.2 Metro-Access Applications
Metro-access networks are characterized by an increasing demand on the part of
residential and business customers for higher bandwidth to support voice, data and
video services.
The compact XDM-100 offers scalable STM-1/4/16 or OC-3/12/48 aggregation of
access traffic in multirings and point-to-point topologies. The platform adds/drops
various 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.

2.3 Cellular Applications
As the cellular market continues to boom, it is essential for operators to deal with
constant increases in traffic, changes in connectivity demands affecting network
topologies, and migration to new technologies (GSM to GPRS to 3G). All of these
changes require scalable and flexible optical infrastructure expansions down to the
RAN (Remote Access Network).
When placed in hub RAN sites, the XDM-100 supports:
♦ Aggregation of low-order traffic generated at BTSs (Base Station
Transceiver Stations)/Node Bs into higher link rates
♦ Consolidation of data traffic with TDM traffic for shared infrastructure
♦ Point-to-point rings and mesh topologies
♦ Closure of multiple STM-1/OC-3 rings (BTS/Node B collector rings)
♦ Closure of higher bitrate rings towards remote BSC or RNC centralized sites
(STM-4/16 or OC-12/48 rings)
♦ Efficient handling of advanced data services (WLAN and IP migration) and
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.
