Alcatel-Lucent 735x ISAM FTTB Product Portfolio 7
Distributed DSLAMs – 24x fewer nodes to manage
The 735x FTTB product family not only supports the
standard fiber and Ethernet aggregation technologies, it
also offers the unique “Distributed DSLAMs” concept.
With this approach to aggregation, the Alcatel-Lucent 7330
Remote Aggregator serves as a host for remote REMs and
SEMs. As a result, the number of nodes in a remote deploy-
ment is reduced by a factor of 24x. This is because the
remotes are managed, not as individual nodes, but as
remote host linecards. This brings three advantages:
• Low aggregation CAPEX — The number of costly
aggregation ports in the Ethernet MAN is reduced
by the same factor of 24x.
•Cheaper and faster operations — Alarm management,
software upgrades, and system configuration and mainte-
nance are reduced by the same factor, reducing required
staff and maintenance duration.
•Faster roll-out — Using the same line cards across the
ISAM family not only means that the same service can
be offered, but also results in faster qualification, easier
training, simpler stock management, and faster feature
availability roll-outs.
Virtual ONT – Consolidated management
of copper and fiber users
By incorporating the Virtual ONT concept, the Alcatel-
Lucent 7352 ISAM FTTB ONT lets service providers
manage QoS for fiber and copper users in precisely the
same way. Each VDSL copper user has the same QoS
management as FTTH/GPON users, and is treated, in
effect, as if each is a fiber user (i.e., with the same type
of GPON T-CONTs mechanism). As a consequence,
service providers enjoy significantly reduced OPEX.
Alcatel-Lucent Smart DSL –
Unprecedented line stability
Line stability is crucial for IPTV and streaming video,
because each technology is highly sensitive to errors.
Anything less than superior quality will meet with
subscribers’ complaints. To meet this challenge, the
Alcatel-Lucent 7354 ISAM FTTB RU, the 7356 ISAM
FTTB REM, and the 7357 ISAM FTTB SEM are designed
to take advantage of Alcatel-Lucent’s Smart DSL, an
innovative technology, which significantly increases DSL
line stability. Compared to the standard technique of
increasing the noise margin, which often leads to much
lost bandwidth, Alcatel-Lucent Smart DSL stabilizes lines
at as much as 30 percent higher bit rates.
Smallest MSAN on the market –
Reduced footprint and multiservice access
The Alcatel-Lucent 735x Product Family also boasts the
smallest Multi-service Access Node (MSAN) available
today. As such, the Alcatel-Lucent 7356 ISAM FTTB
REM is ideal for service providers rolling out Very High
Speed broadband services from remote deployments with
a smooth migration for existing ADSL and voice customers.
Its support for the P2P Ethernet line card also provides a
path toward mixed DSL/fiber deployments from the cabinet,
and also offers voice termination. For ease of deployment,
training, and stocking, the FTTB family’s DSL, fiber,
splitter and voice cards are the same ones as those being
used in the CO/FTTN members of the ISAM portfolio.
