19.2.7 Scenario 7: Provisioning the ONS 15454 Proxy Server

The ONS 15454 proxy server is a set of functions that allows you to network ONS 15454s in
environments where visibility and accessibility between ONS 15454s and CTC computers must be
restricted. For example, you can set up a network so that field technicians and network operating center
(NOC) personnel can both access the same ONS 15454s while preventing the field technicians from
accessing the NOC LAN. To do this, one ONS 15454 is provisioned as a GNE and the other ONS 15454s
are provisioned as end network elements (ENEs). The GNE ONS 15454 tunnels connections between
CTC computers and ENE ONS 15454s, providing management capability while preventing access for
non-ONS 15454 management purposes.
