1.5.4 Domain name service
The Domain Name Server (DNS) application resides on a separate
server machine, and its deployment can vary depending on the
installation requirements and customer configuration. It may reside on
the customer intranet and be accessible through the internet, it might
be internal to the Hub and be provided by the customer, or it may be
located on the internet.
1.5.5 Provisioning
Provisioning is the process of adding/removing mobile terminals
to/from the network. The network operator can add a VMT to the
system database through the NMS client interface to the NMS machine.
Typically, the provisioning is part of custom operating procedures.
Some networks may commission, test decommission, ship, then
commission (Carlsbad NOC). In that case when commissioning is done
after the VMT is installed the VMT doesn’t need to be added, just
commissioned again. So, provisioning consists of more than just the
addition/removal of VMTs, it also commissions them. Customers and
VMTs may be grouped in a variety of ways to enable easy management
by the network operator.
1.5.6 Status monitoring
Status monitoring is accomplished through the NMS client for VMT
status. TermViewer at the Support Server is used in a supplemental
fashion. NMS Client and SNMP OpManager monitor Hub equipment.
