DCN example 12 - Using E1 and VC12 management channels to reach
remote OME6130 network elements in SNCP ring with OM4000 and legacy
OSI network element. Transparent DCC used to provided resilient OSI

communications.

In this example (see
10-90), E1 and 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.
The OM4000 network element is connected to the external DCN via two paths.
An OSI connection to the OSI router, and an E1 connection to the IP router.
The OM4000 acts as the GNE for the legacy OSI network element.
Data communication to the OME6130 GNE is achieved using direct E1
management channel to the external DCN router. Connectivity to the remote
OME6130 is achieved using a mix of E1 and VC12 management channels
through the OM4000 and legacy OSI network elements. In order to provide
resilient data communication against any fiber breaks in the OME6130 system,
management channels are required from the routers to both 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.
The VC12 management channel can be terminated on a physical E1 interface
on the OSI network element. An E1 connection must be provisioned from the
OM4000 GNE to the router.

Note: This example is only applicable to SDH networks, as E1 and VC12
management channels are currently supported only for OME6130 network
elements provisioned in SDH mode.
Note 1: OSPF routing protocol will be used on the E1 and VC12
management channels.
Note 2: If the iISIS protocol is used between the OME6130 NEs for DCC
communication, then OSPF cannot be used on the E1 management
channel. In this case, static routes need to be provisioned between the
router and the gateway OME6130 NE.
