Alcatel-Lucent 735x ISAM FTTB Product Portfolio  3
Brokering the  
new world of triple play 
Video has become a key agent of change. Service providers 
are being forced to innovate by offering competitively 
differentiated services and by exploring new business 
models based on targeted advertising, e-commerce integra-
tion, and revenue sharing with application and content 
providers. While services such as these are boosting ARPU 
(average revenue per user), they are also placing unprec-
edented stress on the traditional high-speed Internet 
infrastructure.  
Consider these facts: end users downloaded 100 billion 
Internet video clips in 2007; by 2011, streaming video content 
will increase from 0.3 Exabytes (EBs) to 10 EB. What’s 
more, analysts are predicting 55 million IPTV subscribers 
in three years time. Just as significant, Youtube currently 
accounts for 10 percent of all Internet traffic, while over-the-
top streaming comprises 20 percent. All of this, coupled 
with the fact that the top four user generated content (UGC) 
providers — Youtube, Google, Yahoo, and MSN — with a 
combined audience of 94 million, is driving service providers 
to provide not only the required bandwidth but also the 
necessary quality of experience (QoE) that their end users 
want and expect.        
To meet this challenge — to provide the scalability and 
quality that these video applications require — service 
providers need to determine the best strategy to meet 
escalating bandwidth requirements. Among other things, 
they need to identify the most economical point for fiber 
deployment, while also leveraging their existing copper 
assets. Put somewhat differently, they need to find a cost-
effective solution capable of assuring the QoE required to 
deliver triple play services in both high and low density 
areas. The good news is that, in combination with Alcatel-
Lucent ISAM portfolio, the Alcatel-Lucent 735x FTTB 
ISAM Product Family is letting service providers extend 
the triple play offer to all subscribers in order to achieve 
100-percent coverage.
The Alcatel-Lucent 735x ISAM FTTB Product Family 
is the newest addition to the ISAM family, and gives 
service providers the flexibility and scalability neces-
sary for the successful delivery of triple play services. 
By allowing operators to deploy DSLAM equipment 
closer to the subscriber — typically in building, curb, 
or cabinet deployments — the Alcatel-Lucent 735x 
ISAM FTTB Product Family enables cost-effective 
delivery of triple play services. Besides the standard 
Ethernet and GPON aggregation technologies, the 
735x family also supports the unique Distributed 
DSLAM concept, which allows operators to manage 
small DSLAMs as remote linecards of a central host, 
resulting in low aggregation CAPEX and low OPEX.
