The Alcatel-Lucent 1850 Transport Service Switch
(TSS)-100, a new class of multiservice transport
platform for metro-core and regional applications,
supports any mix of traffic, from all-circuit to all-
packet. This universal switch uniquely addresses
the transition from TDM/circuit to packet transport,
eliminating the problems encountered when tra-
ditional platforms face data-traffic increases. The
functional versatility of the 1850 TSS-100 allows
operators to support current network demands,
while positioning their infrastructure for the future
growth in advanced service delivery and traffic.

Transforming transport networks
To stay profitable, operators must focus on new revenue-generating services
while carefully controlling their cost structures. At the same time, new band-
width-hungry services, such as triple play and Ethernet virtual private networks
(VPNs), are redefining the underlying transport-infrastructure requirements.
These changes are driving the move from circuit-based transport, using TDM,
to packet-based transport, using Ethernet in MANs and WANs.
Driven by end-user demand for new services, operator network capacity is
growing rapidly, with these networks transporting a wide variety of traffic.
Operators all need to assess how their existing metro and core networks will
accommodate trends and transitions in traffic patterns.
The new-services introduction is probably the most critical factor to an operator’s
success. The increasing demand for bandwidth to deliver new services is not
reflected in comparable increases in revenue, presenting a significant business
challenge. The Alcatel-Lucent 1850 TSS-100 helps operators maximize their
profitability by transporting any service mix while keeping tight control on costs.

The 1850 TSS-100 is a multiservice
transport platform that supports
any mix of traffic, from all-circuit
to all-packet. Its unique, technology-
independent universal matrix switches
packets or circuits in their native for-
mat and transports them as they are,
optimizing overall network efficiency
and applicability. This capability al-
lows operators to address transitioning
from TDM/circuit-based transport
to packet transport with the flexible
provisioning of carrier Ethernet/trans-
port, SONET, wavelength division
multiplexing (WDM) and optical
transport networks (OTNs).
The 1850 TSS-100 supports current
and future traffic requirements by
eliminating the scalability issues
encountered by traditional multiser-
vice provisioning platform (MSPP)/
multiservice transport platform (MSTP)
solutions. The 1850 TSS-100 is the
ideal building block for evolving trans-
port networks, allowing operators to
flexibly split increasing traffic demands
among any combination of carrier
transport technologies. See Figure 1.

The universal switch
The Alcatel-Lucent 1850 TSS-100 offers operators a
powerful tool for operating future-safe transport networks,
with total freedom in planning network resources to support
the delivery of new broadband applications such as triple
play, video, mobile and Ethernet business services. It also
ensures seamless interworking with the legacy transport
assets that support existing revenues, while fully addressing
the optical-packet transport convergence, as demanded by
operators. This offers the following advantages:
•SupportsanymixofEthernet,TDM,WDM,OTNand
future services with only a simple change of interface
cards, eliminating the need for future switch investments
as new services or protocols emerge.
•Offersatechnology-independentuniversalswitch,
capable of switching packets or circuits in their native
format and transporting them as they are, without costly
mapping of circuits into packets or packets into circuits.
The universal switch provides scalable switching capacity
regardless of the traffic type.
•Deliverstechnology-dependentlinecards,packet,circuit
or wavelength, where traffic is properly processed according
to its native format. The line cards provide native
traffic processing.
•Eliminates,byinnovativelydemarkingbetweentrafc
processing and traffic switching, the cost penalties
traditional transport-node architectures incur with
their technology-dependent processing performed in
the switch (matrix). Packet and TDM traffic processing
resides on the relevant line cards, allowing gradual
investment to meet growing traffic requirements.
The concept of a single transport-aggregation platform
is a breakthrough in operator networking. Instead of
investing in several network layers to provide the required
service mix, operators can now choose one platform
that delivers all services. By deploying the 1850 TSS-100
as a unified transport platform supporting any mix of
services, operators can:
•Simplifynetworkoperations,signicantlyreducing
operating expenditures (OPEX) and increasing the
network flexibility and scalability
•Lowertheriskofcapitalexpenditures(CAPEX)invest-
ments that may vary over time, depending on service-
demand changes
•Shortentime-to-revenuefornewservices

Migrating to a packet
transport network
Leveraging its universal, open architecture, the 1850 TSS-100
allows operators to migrate their transport networks from
all-circuit to all-packet. It integrates a full set of SONET
features to support traditional transport-network architec-
tures and to interwork with a large, existing installed base
of equipment.
In addition, the platform supports transport packet switching,
such as packet Operations, Administration, Maintenance
and Provisioning (OAM&P), and integrated G.709 Optical
Transport Hierarchy (OTH) trunk cards. The 1850 TSS-100
provides a cost-effective solution for implementing resilient
metro and aggregation networks. This solution uniquely
transitions from TDM/circuit to packet transport by smoothly
migrating toward the delivery of packet-based services,
maximizing return on investment over the network lifecycle.
The 1850 TSS offers Fast Ethernet (FE) and Gigabit
Ethernet (GigE) interfaces for interconnecting with
customer equipment or operator access equipment, deliv-
ering carrier-class circuit and packet services. It also sup-
ports stacked unidirectional path-switched rings (UPSRs)
and bidirectional line-switched rings (BLSRs), with non-
blocking aggregation and TDM traffic switching, or Layer
2 Switched Ethernet. These features offer cost-effective
solutions for implementing resilient metro and aggregation
networks and switched Ethernet-to-Ethernet.

CombiningcircuitandpacketinterfacesandusingEthernet-
based traffic management, the 1850 TSS-100 supports
multiple Quality of Service (QoS) levels to provide a
migration path toward the delivery of advanced packet-
based services. It also ensures a smooth network evolution
by enabling hybrid networks with totally flexible resource
allocation between circuit and packet data services while
fulfilling the roles of traditional MSPP/MSTP platforms.

Triple play over optical
Introducing triple-play services establishes new broad-
band-aggregation infrastructure requirements for both
scalability and the speed of service rollout. To meet these
goals, many operators are introducing Ethernet into their
broadband-access infrastructures. This allows network op-
erators to progressively integrate their triple-play services
into a unified and homogeneous environment.
The 1850 TSS-100 can efficiently provide distributed
broadband service aggregation and transport toward the
broadband service routers. It is a unified transport plat-
form, offering flexible support when transitioning from
legacy transport to Ethernet. The unified aggregation
platform supports any multiservice business model and
protects infrastructure investments.
When distributing video, it is important to broadcast
these services from the last possible point in the network
to avoid duplicating service costs inside the network. With
a dedicated Ethernet network or a multiservice network,
the multicast can be done efficiently at either the TDM
or Ethernet level. The 1850 TSS-100 can use a combina-
tion of distributed Layer 2 and TDM Switching, depend-
ing on the option that suits the provider’s requirements
and minimizes costs (see Figure 2).

Supporting business services
Enterprises are increasing their use of high-bandwidth
applications and they are more frequently interconnecting
LANs and data centers within a metro area. To address
this market, operators need scalable, carrier-class solutions
that offer operators guaranteed QoS levels, support for
differentiated SLAs and customer separation. Operators
can build either dedicated Ethernet networks or multiservice
networks able to provide other services through the same
networking platform. The 1850 TSS-100 supports both of
these models.
Wireless network traffic is increasing significantly with
growth in subscriber usage and the introduction of new,
wireless data services, such as video telephony, music, Internet
surfing and live television, along with video-on-demand
(VoD). Price-based competition makes profitable growth
a challenge. Nevertheless, operators are forced to invest
in new infrastructure to serve their customers’ needs. Should
they expand with TDM technology for more capacity now
and worry about strategically evolving to 3G and all-IP
later, or can they expand innovatively, making the net-
work better now, while anticipating future requirements?
The 1850 TSS-100 helps operators introduce new business
services, either by leveraging the installed base, or by
introducing a single platform to replace multiple tradi-
tional systems. In both instances, providing a fully flexible
and reliable transport platform that meets today’s growth
requirements for both Ethernet- and TDM-based traffic
opens the door for a strategic move toward an IP-based
infrastructure.

Network management
Operators need to focus on the service, rather than the technology, where it is used, how the
network scales and how complex it is. By migrating from a technology-based network management
model to a service-oriented one, the complexity of managing services is greatly reduced. Alcatel-
Lucent offers two management platforms for operators, depending on their network requirements
and planned evolution: the Alcatel-Lucent 1350 Open Media Suite (OMS) and the Alcatel-Lucent
1340IntegratedNetworkController(INC).
The 1350 OMS management suite eliminates the need to deploy multitechnology element and network
managementsystems,reducingCAPEXandOPEX.Itoffersahighlymodulararchitecturetoproperly
