In 2005, to show operators how the technology
behaves and what services it supports,
Ericsson deployed EDA with VDSL2
in live networks. Some features of EDA
worth highlighting in the context of VDSL2
are scalability, advanced single-ended line
test (SELT) and double-ended line test
(DELT) capabilities, QoS, and greater capacity.
Vital objectives of the early deployments
were
• to verify VDSL2 performance advantages
in real network conditions; and
• to enable an early start of VDSL2 interoperability
activities.
