Management Interfaces and Connections of OptiX OSN 8800/6800A

Interfaces

For OptiX OSN 8800/OptiX OSN 6800A, the NM_ETH1/NM_ETH2 interfaces on the

TN51ETH1/TN51ETH2/TN16EFI boards are used for achieving inter-NE communication.

The ETH1, ETH2, and ETH3 interfaces on the TN51ETH2/TN16EFI boards are used to

achieve intra-NE communication. Table 1 provides the correct connections of these

network interfaces.

Connections

On a network where only OptiX OSN 8800 or OptiX OSN 6800A NEs are used, intra-NE

and inter-NE communication are achieved through fiber connections and network cable

connections.

NE Connections

Figure 1 and Figure 2 show the NE connection scheme. The figure presents

connections

between two NEs: NE1 and NE2. Each NE consists of three subracks, one of which is

the master subrack and the other two are slave subracks. The master and slave

subracks are connected using fibers and network cables.

Inter-NE communication:

l As shown in the figure above, NE1 connects to the NMS through the NM_ETH1 4

interface

on the EFI2/EFI board in the master subrack using a network cable, enabling the NMS to

manage the two NEs.

l Inside each NE, OTU, OADM/OA/OM/OD, OSC, and FIU boards are properly

connected

through fibers. The FIU boards are also connected to other NEs. ESC or OSC channels

are used to achieve inter-NE communication.

l The NM_ETH2 interface on the EFI1/EFI board in the master subrack of one NE is

connected to the NM_ETH1 interface on the EFI2/EFI board inside the master subrack of

the other NE using a network cable, achieving inter-NE communication over Ethernet

channels.

Intra-NE communication:

For each NE, the ETH2 and ETH3 interfaces on the EFI2/EFI board inside the master

subrack are connected to the ETH1 interfaces on the EFI2/EFI boards in the slave

subracks to achieve communication between the subracks.

Management Connections among OSN8800&6800A&3800A

On a hybrid network where OptiX OSN 8800, 6800A, and 3800A NEs are used, the inter-

NE communication and intra-NE communication are achieved through fiber connections

and network cable connections.

Connections

Figure 3 shows the NE connection scheme. The figure illustrates how three NEs (namely

NE1, NE2, and NE3) of different types are connected. As shown in the figure, NE1

consists of a master subrack (OptiX OSN 8800) and two slave subracks (OptiX OSN

8800 T16/6800A); NE2 and NE3 are two OptiX OSN 3800A NEs.

Inter-NE communication:

l As shown in the figure above, NE1 connects to the NMS through the NM_ETH1

interface

on the EFI2 board in the master subrack using a network cable, enabling the NMS to

manage all the NEs.

l The OTU, OADM/OA/OM/OD, OSC, and FIU boards inside NE1 are connected through

fibers. The FIU boards are also connected to other NEs. ESC or OSC channels are used

to achieve inter-NE communication.

l NE2 and NE3 are connected through their OTU, OADM/OA, OSC, and FIU boards

using

fibers. The FIU boards of the two NEs are also connected to other NEs. ESC or OSC

channels are used to achieve inter-NE communication.

l The NM_ETH2 interface on the EFI1 board of the master subrack inside NE1 connects

to

the NM_ETH1 interface on the AUX board inside NE2 through a network cable. The

NM_ETH2 interface on the AUX board inside NE2 also uses a network cable to connect

to the NM_ETH1 interface on the AUX board inside NE3. In this manner, all the NEs

communicate with each other using Ethernet channels.

Intra-NE communication:

For NE1, the ETH2 and ETH3 interfaces on the EFI2 board inside the master subrack 6

are

connected to the ETH1 interfaces on the EFI2/EFI boards in the slave subracks to

achieve

communication between the subracks.
