Figure 31 Linear (point-to-point) ADM configuration
The ONS 15327 supports a full range of line rates as well as TDM and Ethernet/IP
access tributary interfaces at every node in ADM configuration. The
cross-connect helps to maximize bandwidth allocation by making it possible to
map any tributary STS channel to any eastbound or westbound SONET span or to
any other access tributary interface.
You can set up an ADM configuration in a few steps using CTC. At turn-up,
identify the ONS 15327 network element as part of a linear (non-ring) ADM
configuration. The ONS 15327 auto-detects connected network elements through
any established transport spans. You can modify default settings as needed.
Terminal Point-to-Point
In terminal point-to-point configuration, one node is physically connected to
another node with no intermediate nodes. The add-drop multiplexing feature is
usually provided but not used in this configuration.
