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

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
