2 The Shared DSL Solution
The Shared DSL solution is a new, cost effective, and secure way of
unbundling DSL, when the primary Access Provider is not the owner of the
EDA network. The secondary Access Provider (who owns the EDA
network) simply extends the EDA network through the primary Access
provider network. The Shared DSL solution is targeted towards data
services like Internet Access.
2.1 Shared DSL Concept
In a situation where another Access Provider owns the line to multi
dwellings, leasing a line for each End-user (subscriber) can be expensive.
The Shared DSL concept calls for leasing only one line, then creating a
remote EDA site. The connected End-users share the DSL line capacity,
while maintaining the EDA system security and benefits. For the Secondary
Access Provider, managing the remote site is almost the same as
managing nodes and End-users in a standard EDA network.
