4.6.2.3 DCC Links
The lines between nodes in the network view indicate DCC connections between the nodes. Active DCC
connections appear as green/solid or green/dashed. Solid means circuits can be routed through the link,
and dashed means circuits cannot be routed through the link. A gray link is in a fail state.
4.6.2.4 Link Consolidation
CTC provides the ability to consolidate the DCC, general communications channel (GCC), optical
transport section (OTS), provisionable patchcord (PPC), and server trail links shown in the network view
into a more streamlined view. Link consolidation allows you to condense multiple inter-nodal links into
a single link. The link consolidation sorts links by class, meaning that, for example, all DCC links are
consolidated together. You can access individual links within consolidated links using the right-click
shortcut menu.
In OSP installations, the ONS 15310-MA SDH cannot be monitored through a standard Ethernet/LAN
connection. So an alternate connection is established through the optical link of the aggregated client
traffic (SDH) and a supporting Network Element (NE). The support node (installed indoors) and the
ONS 15310-MA SDH OSP node are set up with a direct IP access to a far-end ONS 15310-MA SDH
OSP node over a Data Communications Channel (DCC) network.
Each link has an associated icon (Table 4-9 ).
Note Link consolidation is only available on non-detailed maps. Non-detailed maps display nodes in icon
form instead of detailed form, meaning the nodes appear as rectangles with ports on the sides. Refer to
the Cisco ONS 15310-MA SDH Procedure Guide for more information about consolidated links.
