3. DSL Card Configuration
8000-A2-GB26-50 April 2001 3-3
Domain Types
To monitor and control the overall system, the Hotwire Access Network should be
partitioned into two distinct domains:
Service domain(s) (Layer 2, MAC Bridging)
Management domain (Layer 3, IP Routing)

Service Domain

A service (or data) domain is comprised of all clients and s ervers (grouped
physically or virtually) that communicate across a common WAN or LAN
connection for Internet or intranet access. This is the Layer 2 bridging domain of
the NSP. The Access Node cards and the Service Nodes are the Hotwire
components of this domain. The service domain also encompas ses an NSP and
all end-user systems that subscribe to that NSP.

Management Domain

The primary function of the management domain is monitori ng and configuring the
DSL cards and service domains served by the DSLAM. The management doma in
should reside in a mutually exclusive domain from that of the service (data)
domain(s). The MCC card functions as a service router and is the primary tool for
configuring and diagnosing the management domain.
It is recommended that the management domain reside in a separate domain fr om
the service domain(s) for security purposes and to improve download
performance.
Minimum Configuration
The minimum configuration of the DSL port card differs, depending on the type of
SN used.

Minimum Configuration When Using the 5620, 6310, or 6350 SN

When using either the 5620, 6310, or 6350 SN, the DSL port card is in c ontrol of
the connection. At a minimum, you must configure the following:
VNIDs on a DSL card (see

Configuring VNID(s) on a DSL Card

on page 3-20)
The active VNID and the Next Hop Router on each DSL port/interface (see

Configuring the Active VNID and the Next Hop Router on each DSL

Port/Interface

on page 3-22) when using DHCP
Static users (see

Configuring Static Users

on page 3-23) if you have static
users on your network, fixed addresses, or subnets
