Broadband aggregation
for triple Play
Introducing triple play services
establishes new requirements for
the broadband-aggregation infra-
structure for both scalability and
the speed of service rollout. To meet
these goals, many service providers
are introducing Ethernet into their
broadband-access infrastructures.
This type of infrastructure allows
network service providers to progres-
sively integrate their triple play
services into a unified and homoge-
neous environment.
The Alcatel-Lucent 1850 TSS-320
can provide efficiently distributed
broadband service aggregation and
transport toward the broadband
service routers. The Alcatel-Lucent
1850 TSS-320 is a unified transport
platform, offering flexible support
during the transition from legacy
transport to Ethernet. The unified
aggregation platform supports any
multiservice business model and
protects infrastructure investments.
For distributing video, it is important
to broadcast these services from the last
possible point in the network to avoid
costs from duplicating services 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 Alcatel-Lucent 1850 TSS-320 can
use a combination of distributed Layer 2
and TDM switching, depending on
the option that suits the provider's
requirements and minimizes costs
ethernet Business services
Enterprises are increasing their use
of high-bandwidth applications and
they are more frequently intercon-
necting LANs and data centers within
a metro area. To address this market,
service providers need scalable, carrier-
class solutions that offer guaranteed
quality of service (QoS) levels, support
for differentiated service level agree-
ments (SLAs) and customer separation.
Service providers can build either
dedicated Ethernet networks or
multiservice networks able to provide
other services through the same
networking platform. The Alcatel-
Lucent 1850 TSS-320 supports both
of these network models.
