8.2.7 Scenario 7: Provisioning the ONS 15310-MA SDH Proxy Server
The ONS 15310-MA SDH proxy server is a set of functions that allows you to network ONS 15310-MA
SDH nodes in environments where visibility and accessibility between nodes 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 nodes while preventing the field technicians from
accessing the NOC LAN. To do this, one ONS 15310-MA SDH node is provisioned as a gateway
network element (GNE) and the other nodes are provisioned as end network elements (ENEs). The GNE
tunnels connections between CTC computers and ENEs, which provides management capability while
preventing access for non-ONS 15310-MA SDH management purposes.
The ONS 15310-MA SDH proxy server performs the following tasks:
