The EDA system network may have up to 20 Access Domains. Each
Access Domain can have up to 2,000 IP DSLAMs. The maximum number
of end-users in the EDA system network is approximately 1000,000.
If the number of end-users exceeds the maximum, multiple EDA systems
can be deployed.
Figure 3 The Access Network
3.1.2 Domain Subnets and IP Networks
The Access Domain comprises one or more IP Networks each defined by a
Network ID, a Subnet Mask and a Default Gateway, and comprises one or
more Domain Subnets, see Figure 4 on page 10.
Each IP Network in the Access Domain is divided into a number of Domain
Subnets. The Domain Subnet contains the network elements that are the
EDA nodes like IP DSLAMs, FE-E1 converters, and EDA switches.
An IP range is defined in each Domain Subnet for network elements, which
dynamically receives IP addresses from a DHCP Server. (Component of
the Domain Server), unless the EDA network is based on the Ethernet
Access Node (EAN), where the Domain Server function is an integrated
part of the ECN330/ECN320.
