Management Domain Components
The following illustration shows the components of the network management
domain. Note that the router between the MCC card’s 10BaseT interface and the
DCE Manager is optional. The MCC card, as previously noted, provides
consolidated management for the DSL cards and HotWire 5446 RTUs from
SNMP workstations or its VT100 interface.

Ordinarily, when DCE Manager
is on a separate subnetwork, it
will not be in the 135.1.3 or
135.1.2 subnetwork.
To facilitate management of the DSL cards and HotWire 5446 RTUs through the
MCC card:
 Assign IP addresses to the internal backplane interfaces of each DSL card
and each HotWire 5446 RTU interface in the same subnet as the MCC card’s
backplane (as shown in the previous illustration).
These IP addresses are stored in the Entity MIB on the MCC card where they
can be accessed by the DCE Manager.
 Provide IP addresses on the router’s interface attached to the MCC card for
both subnetworks, so that the router appears to be directly connected to the
MCC card’s Ethernet interface as well as the HotWire DSLAM system
backplane.
