DCN example 11 - Using VC12 management channels through OM4000
network to reach remote OME6130 network elements in SNCP ring with
OM4000 and legacy OSI network elements. Transparent DCC used to
provided resilient OSI communications.
In this example (see Figure 10-24 on page 10-83 and Figure 10-25 on page
10-84 ), VC12 management channels are used to establish communication
between the external DCN and the OME6130 network element in a SNCP ring
of OME6130, OM4000 and legacy OSI network elements.
Note: This example is only applicable to SDH networks, as VC12
management channels are currently supported only for OME6130 network
elements provisioned in SDH mode.
Dual OM4000 network elements are connected to the external DCN via an OSI
only enabled port and act as the GNEs for the other OM4000 and legacy OSI
network elements.
Data communication to the remote subtending OME6130 network elements is
achieved using VC12 management channels through the OM4000 network
and are directly terminated on the routers. In order to provide resilient data
communication against any fiber breaks in the OME6130 system, two VC12
management channels are required from the routers to two OME6130 network
elements on the ring. Transparent DCC is provisioned on the OME6130
network elements to provide resilient data communications between the
OM4000 and the OSI legacy equipment.
Note: OSPF routing protocol will be used on the VC12 management
channels to the DCN routers.
The VC12 management channel can be terminated on a physical E1 interface
on the external DCN router. An E1 connection must be provisioned from the
OM4000 GNE to the router.
