Access Platform – Network Scenario
High-End Unit- Located Close to PoP- Interconnection With Existing Networks – Circuit Switching, Packet,
CATV Source etc.- Connected to One or More Remote Terminals- Abbreviation - OLT – Optical Line Terminal
Remote Terminals- Located in: Basement or Street-Side- Connection: Copper, Fiber, Coaxial or Wireless to the Subscribers- Abbreviation:
- ONU – Optical Network Unit- ONT – Optical Network Terminator- ENT – Electrical Network Terminator- DRP – Distribution Remote Points- ISU – Integrated Service Unit- IAD – Integrated Access Device- IAU – Integrated Access Unit

Access Bottleneck Issue
- Development of broadband access systems standards and technologies
- Demand for bandwidth and a scalable network infrastructure.- FTTH infrastructure as an alternative to less-scalable xDSL, cable mo
dem and fixed wireless access deployments.- Governments - From the bandwidth-limited information society of toda
y and the bandwidth-rich information society of tomorrow.- Governments - FTTH deployments

米米 Slide 22
Access Network Issue
- Development of broadband access systems standards and technologies
- Service providers - Detailed plan for migrating the different subscriber segments from circuit-switched to pure packet-switched access infrastructures.
Service providers - Ethernet carriers that start to claim a stake in the telecommunications services market.

米米 Slide 23
Access Network Issue
- Development of broadband access systems standards and technologies
- Fiber technologies - Edge of access networks. Home and desktop. - Incumbents - Business models segment by segment.Internet Protocol-based and asynchronous transfer mode-based
access solutions.Competitive operators - Conservative when forecasting payback
periods for new technologies and select their target customers carefully.
