Objective

Upon completion of the module you will be able to

§ explain in your own words the impact of Triple Play services on

a typical data network

§ explain why we need the ISAM

• what is the ISAM? – what can the ISAM be used for?

§ explain the main evolution steps the DSLAM has made in recent

years

Why the ISAM?

12

Impact of the need for speed on access

Multi-service from a single access platform is key.

• Triple Play : Data, voice and Video

New Service are bandwidth intensive:

• Increased switching capacity

• Increase capacity on last mile

Increased need for bandwidth results in …

• new BB access technologies :

o Multi-DSL: ADSL2+

o VDSL2 : symm and asymm

o FTTU : point-to-point and GPON

• deployment of deep fiber & remote devices

• upgraded capacity in the DSLAM
