Introduction to the EDA 1200 System

Figure 6 EDA 1200 Access Network

Some examples of utilizing different drop technologies and network elements

are shown in Figure 6 on page 9 . A second level aggregation switch (Ethernet

Switch) aggregates the traffic from the Access Nodes, and connects them to

the Voice Gateway and Edge Router.

The IP DSLAM supplies the End-users with Broadband services (BB services).

The BB services can include data, video, Telephony over IP and IP telephony.

These services can be supplied on top of existing Narrowband services (NB

services).

The Fiber Node supplies the End-users with BB services (the same BB services

as the IP DSLAM). The Fiber to the Home (FTTH) ensures a very high and

symmetrical bandwidth both upstream and downstream. Despite the name, the

fiber node (EFN) is also available as a CAT5 node.

An example of utilizing specific network elements is illustrated for the remote

site. In this example, vacant twisted pair copper wires are used as E1 or T1

using EDA 1200’s Fast Ethernet to E1 converter to transport the traffic. Other

vacant twisted pairs are used to supply the remote site with power (-48 V DC).

The power is then distributed to the nodes by an Ethernet Power Node (E

Power Node) over the Ethernet connections.

Most of the EDA 1200 nodes uplink connections facilitate both electrical and

point to point optical connections. The optical connection enables the use

of FTTx:
