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.

2.1Shared 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.
